Mobile Internet: How Much Data is 500MB or 1GB? Download Limits Explained

April 2nd, 2014

Mobile phone contracts often have a limit on how much you can download. In the real world, what can you actually do with 500MB or 1GB?

Smartphones Consume DataWhen using a smartphone, you’ll need to have a suitable tariff with a large enough data allowance.

Almost all of the functionality on a modern smartphone requires data to work. Data is consumed when browsing the internet, sending instant messages, reading e-mails, watching YouTube videos, updating Facebook and Twitter and calling friends over Skype. Every activity consumes data at a different rate.

In the UK, there’s a wide range of tariffs with varying download limits. Most contracts give you around 1GB of data per month but there’s a large variation depending on the network you choose. On lower-cost tariffs, you’ll often get 500MB per month. If you’re willing to pay more, you might get an allowance of up to 20GB per month. There’s also a network offering all-you-can-eat data.

In this article, we explain the real-world meaning of mobile download limits. We’ll ask what 500MB and 1GB of data actually correspond to in real life. We’ll also outline figures for average data consumption and we’ll explain how to measure your current data usage. Finally, we’ll provide a few tips on how to choose the right data allowance.

How much data is included on my mobile contract?

If you’re choosing a tariff for your smartphone, the chances are it’ll come with 1GB of data or more every month. For entry-level tariffs, you might have as little as 250MB or 500MB of data. This can be suitable for occasional and light users. On higher-end tariffs, you can get as much as 20GB of data every month. There’s also the option of all-you-can-eat data on Three (unlimited downloads).

The following table show typical data allowances offered by UK mobile networks:

Network Typical Download Allowance Other Tariffs
EE 4GB 4G tariffs: Between 500MB and 20GB
giffgaff 1GB £7.50 Goodybag: 250MB
£10 Goodybag
: 1GB
£12+ Goodybags: Unlimited
4G Goodybags: 500MB or 2GB
Gigabags: 500MB, 1GB or 3GB
O2 2GB O2 Refresh: Between 500MB and 8GB
Tesco Mobile 500MB Pay Monthly: Up to 8GB
Three 1GB Pay Monthly: 2GB or Unlimited
Vodafone 1GB 3G Plans: Up to 4GB
4G Plans: Up to 13GB

As the amount of included data depends on your tariff, we strongly recommend verifying details with your network via the following links:

Relationship between KB, MB and GB

data-binaryThere are 1,000 kilobytes (KB) in 1 megabyte (MB) and 1,000 megabytes in 1 gigabyte (GB).

This means if you see a tariff advertising 500MB of data per month, you can only download half as much as you can on a 1GB per month tariff (500MB = 0.5GB).

You may occasional come across terms such as terabyte and mebibyte. These terms are rarely used within the mobile industry but Wikipedia has a good explanation in case you ever come across them.

What can I do with 500MB or 1GB of data?

It’s hard to give an exact figure. For instance, web pages differ substantially in size. Some websites are incredibly simple (mainly text with a few images) whilst others are much complex (with photos and videos embedded which increases data consumption). In order to produce the table below, we’ve taken a few averages. It should provide a rough guide on what you’re able to do with 500MB or 1GB.

500MB corresponds to… 1GB corresponds to…
Accessing Web Pages 900 pages 1,800 pages
Basic e-mail/instant message 150,000 350,000
Rich e-mail/IM (with attachments) 1,000 2,000
Downloading/streaming music 100 songs 200 songs
Downloading/streaming video 1 hour 2 hours
Skype voice call 15 hours 30 hours
Skype video call 2 hours 4 hours
Listening to online radio 8 hours 16 hours
Downloading/updating apps 40 apps 75 apps

Approximate figures for what you’re able to do with 500MB or 1GB of data. See the table below for a list of assumptions.

Please note that we’ve listed what 500MB and 1GB correspond to: this isn’t a shopping list of what you can download with a 500MB or 1GB allowance. In other words, viewing 900 web pages, watching 1 hour of video or downloading 40 apps would use up the entirety of a 500MB allowance (a 500MB allowance does not allow you to do all of them in the same month). Realistically, you’ll do a bit of everything so each activity would contribute towards your total data usage.

How much data does the average user require?

We would typically recommend choosing a tariff with at least 2GB of data per month. This is based upon statistics for average data consumption and also allows for some data usage increase over the next 24 months.

In July 2012, Three reported that the average customer used 1.1GB per month. More recently, the CEO of EE announced in a speech that average data consumption was 1.4GB per month (statistics from February 2014). Based on these figures, 2GB per month should be ample for most users. For heavy smartphone users, consider an even larger allowance: perhaps in the region of 4-5GB per month.

At present, our recommended deal is Three’s all-you-can-eat unlimited data plans. Compared to other networks, you’ll pay a lot less and you’ll never need to worry about how much data you use (other networks offer around 1GB of data for the same price as unlimited data on Three).

How do different activities contribute to data consumption?

iPhone Apps

Almost all activities on a smartphone will consume data.

Almost all activities on a modern smartphone will consume data – the main exceptions being making a phone call and sending a text message.

Activities consuming data include: browsing the web, reading and sending e-mails, browsing Facebook and Twitter, sharing photos, updating your status, downloading applications, downloading music, listening to online radio and watching videos on YouTube. Instant messaging and voice over IP apps (Skype, WhatsApp, BBM, Facebook Messenger, etc) also consume data when in use.

Your phone will also consume data in the background when you’re not using it. For example, your e-mail application automatically checks for messages periodically throughout the day. Also, the weather widget on your home screen updates itself automatically by downloading the latest forecast from the internet. Your phone could also be downloading application updates automatically in the background. When choosing a data tariff, you should always allow extra for background data usage.

Table: Rates of Data Consumption

The following table gives a rough guide on how different activities contribute to data consumption:

Mobile Data - Messaging Basic E-mail or Instant Message (e.g. Gmail, WhatsApp)
0.003MB per message (3KB, no attachments)
Mobile Data - Rich Email Rich E-mail or Instant Message (with attachment)
0.5MB per message (500KB)
Mobile Data - Browsing Web Browsing
0.6MB per web page (600KB), approximately 35MB per hour of web surfing
Mobile Data - Music Downloading or Streaming Music (e.g. MP3 files, Spotify)
  5MB per song
Mobile Data - Apps Downloading or Updating Apps
  13MB per app
Mobile Data - Skype Voice Skype Voice Call
  35MB per hour
Mobile Data - Online Radio Listening to Online Radio
60MB per hour
Mobile Data - Skype Video Skype Video Call
240MB per hour
Mobile Data - Online Video Downloading or Streaming Online Video (e.g. YouTube, iPlayer)
500MB per hour

How do I find out how much data I currently use?

Android 4 Data Usage Monitor

Android handsets include a ‘Data Usage Monitor’.

There’s two ways to find out how much data you’re currently using: either ask your network or find out from your smartphone’s data usage monitor. In general, the most reliable figure will come from your mobile network. The easiest way to get hold of these stats is to log in to your mobile network’s website:

  • EE (My EE, includes Orange and T-Mobile customers)
  • O2 (My O2)
  • Three (My 3Account)
  • Vodafone (My Vodafone)

There may also be an app from your network: it’ll often show how much data you’ve used. Compared to the online version, the application can often be more convenient.

The second method of measuring data consumption is through your smartphone’s data usage monitor. It’s available on most Android handsets (including Samsung Galaxy, HTC One, Sony Xperia and LG handsets). Within the Settings app, choose the Data Usage option.

The data usage measured by your phone may differ slightly from your network operator’s measurement. Your charges will be based upon your network operator’s measurement. For this reason, we normally recommend consulting your network operator.

Note: If you’re buying a new phone, your current data consumption may not be a good indicator of how much data you’ll use in the future. Newer handsets often have more advanced functionality so you should expect data consumption to increase after the upgrade.

How can I reduce my data consumption?

If you’re running out of data, you can reduce your data consumption by following these tips:

Data transferred over wi-fi does not count towards your download limit.

Data transferred over wi-fi doesn’t count towards your mobile download limit.

  • Use Wi-Fi whenever you’re at home. Whenever you’re in range of a wi-fi internet connection, connecting to it will help to reduce your mobile data consumption. As your data will be routed over wi-fi, you’ll save precious mobile data for when you actually need it. You can often find free wi-fi internet at coffee shops and restaurants.
  • Avoid using bandwidth-intensive apps. If you’re not connected to a wi-fi network, refrain from streaming music and video from the internet. Applications such as Spotify, BBC iPlayer, YouTube, NetFlix and TVCatchup will very quickly exhaust your download allowance. You should also avoid tethering and using voice-over-IP or file sharing applications.
  • Disable automatic application updates. Application updates can use up a large proportion of your monthly download allowance. If you receive 10 application updates per month, this would use around 130MB. Within Google Play (Android), press the menu button followed by Settings. For the automatic update setting, either choose “Auto-update apps over Wi-Fi only” or “Do not auto-update apps”.
  • Use bandwidth saving apps. Applications such as Onavo and Opera Mobile can reduce your data consumption. They do this by compressing data before it is transferred to you over the network.
  • Disable bandwidth-hungry apps. On Android, it’s possible to see how much data each app is consuming. To do this, navigate to Settings > Data Usage. Consider removing bandwidth-heavy apps. Alternatively, restrict their ability to use background data.

Frequently Asked Questions

Does data transferred over wi-fi count towards the monthly download limit?

No: your mobile network operator will only count data transferred over the mobile network. When using wi-fi, data bypasses your mobile network entirely. As such, it won’t be counted towards your download limit. To better preserve your mobile download allowance, it’s always a good idea to use wi-fi at home. This will save some of your allowance to be used later when away from the home. Wi-fi can also give a more reliable experience for data-intensive apps (e.g. listening to online radio, making a Skype video call or watching TV online).

How much data is used by tethering or portable hotspot?

TetheringTethering or “portable hotspot” refers to the process of sharing your phone’s mobile internet connection with other devices. It’s often used to connect devices such as a tablet or laptop.

When tethering, any data consumed on your tablet or laptop will also count towards your mobile download limit. The figures given in the table above should still be broadly accurate when using other devices (simply include all of the content accessed from a tethered device). As an extra point, please bear in mind that tablet and laptop users more often use data-intensive apps (you might be watching more videos on your laptop). Also, keep an eye out for automatic updates on your PC: they can quickly use up large amounts of data. Consider disabling automatic updates before tethering from your phone.

To monitor data consumption on a tethered PC, we recommend using the free tbbMeter app (Windows only). For Mac and Linux computers, you can use the free BitMeter OS.

Does listening to radio count towards my download allowance?

iPlayer Radio

Yes, but only if the radio station was received over the internet. If you’re listening to radio through an app or through the browser, it’s likely to have been received over the internet. A 500MB allowance will allow you to listen to 8 hours of online radio.

To listen to radio without consuming data, it’s sometimes possible to tune in to a FM broadcast. As FM radio is received over public airwaves, listening in will not count towards your download allowance. Unfortunately, many new smartphones lack support for a FM radio tuner (neither the iPhone 5s or Galaxy S5 support FM radio).

Can I use my download allowance abroad?

In general, your download allowance can only be used within the UK. If you’re using a smartphone abroad, there may be extra charges for connecting to the internet. Data roaming charges will depend on the network and also the country you’re visiting. In some cases, you can expect to pay up to £10/MB. To reduce the costs of using data abroad, consider taking advantage of one of the following deals:

EE

EE Euro Roaming Data Add-On – 100MB Of Data in Europe (£3/day)

    Hello~ I have been looking at my son’s data usage and everyday he has been using at least 106.7000 MB’s and sometimes even higher. Can FACETIME use this many MB’s? Websites??

      Ken replied:

      Hi Karen,
      Thanks for your comment. If you’re using FaceTime over mobile/cellular data, it will consume data at a very fast rate (around 3-4MB per minute). Expect to use around 240MB for every hour spent making a FaceTime video call. With regards to web browsing, this can also play a significant role in mobile data consumption. Expect to use around 35MB for every hour spent browsing the web. To reduce your data consumption, it’s always worth using FaceTime on a wi-fi connection. It’s also good to browse over wi-fi if the phone is being used at home.
      Hope this helps,
      Ken

    I stopped in a Sprint store. They gave a wi-fi box for 100 dollars with 50 dollars rebate. You can have 1GB or up to 12 gigs. The 12GB package is 80 dollars a month. Now AT&T has a hotspot. Its data is what is in your Family share plan and is 15 dollars a month just to own.
    It sounds to me like the Sprint has something going here. Or am I wrong… what is the difference between wi-fi and data usage? What’s the difference between wi-fi and a hotspot?
    thank you, patty

      Ken replied:

      Hi Patricia,
      Thanks for your comment. I’m not 100% clear how the two deals compare: from the sounds of your comment Sprint is providing a mobile broadband service complete with a portable wi-fi hotspot whereas AT&T is simply allowing you to tether from your phone. They’re slightly different things (on the latter option, you use your existing data plan & the smartphone you already have) but achieve the same outcome i.e. being able to use the internet whilst on-the-go. The two guides I’ve linked to should help to explain the difference :)

    very useful summary, thanks Ken.

    I’m starting from the other end and have an idea for an app. I need to calculate likely data use from a hosting POV. Any thoughts on best way to do this?

    1. Ken Lo
      Ken replied:

      Hi Pat,
      Thanks for your comment. It’s really difficult to say the likely data usage when hosting an application: it really depends on what resources will be downloaded from the server (presumably, the app itself will come from elsewhere e.g. iTunes or Google Play). To gain an estimate, I’d probably run the app a couple of times and then multiply the data usage by the expected number of users.

  4. Geraint Williams said:

    Many thanks for your reply I will certainly try that. Not being such a tech whizz will I be able to switch off the automatic updates?

    1. Ken Lo
      Ken replied:

      Hi Geraint,
      If it turns out that Automatic Updates are indeed responsible for the high data usage, you can turn it off using the instructions here. I would only recommend following this guide if you’re sure the automatic updates are causing the data usage (otherwise, it’ll make your laptop less secure and won’t actually reduce the amount of data used).

    Need some help! I have a lap top but no phone line so connect to the internet through a mobile wi fi device with O2. I have a monthly data allowance of 3gb. When I connect the lap top to the mobile wi-fi I start using lts and lots of data straight away even before accessing pages or apps etc. it can use between 50mb and 100mb within minutes! My mobile wifi device shows that only my lap top is connected so isn’t another device using the data. Any ideas? Are there apps automatically updating? I’ve used 1.2gb of data in 4 days! I work all day and only use it for hour or so at night and not even been streaming videos or music, where is my data going!?

    1. Ken Lo
      Ken replied:

      Hi Geraint,
      Thanks for your comment. One danger of tethering or using mobile broadband is that your laptop will often use data without you doing anything. Common culprits are automatic software updates (e.g. Windows Update, anti-virus definitions, Firefox or Chrome) and cloud storage sync (e.g. OneDrive or Dropbox). The easiest way to find the offending application is to press Ctrl+Alt+Del followed by “Start Task Manager”. On the “Performance” tab, click on “Resource Monitor”. Underneath the “Network” heading, you’ll see a list of applications currently using data.
      Hope this helps!

    Great and very informative article, thank you! I have a few questions.

    I am in the process of buying a new phone (samsung galaxy S5) off of a contract. The two available options of data usage are 1gb and the 3gb per month. I’m wondering whether 1gb is enough for a whole month, or if it’s worth paying more (around 200$ more) for 3gb?

    I always use wifi at home, & I don’t use apps such as spotify, skype, facebook etc. Also Most of my time on the internet is spent reading articles or watching short vids etc.

    Thanks

    1. Ken Lo
      Ken replied:

      Hi lelouch,
      Thanks for your comment. It’s difficult to know without seeing exactly how you use your phone – I’d say if you’re using wi-fi at home and if you’re not using data-intensive apps, 1GB per month should be sufficient for your usage. That said, you mention you often watch videos. This can quickly deplete the amount of available data (two hours of video per month or 4 minutes per day will use up the entirety of 1GB). Perhaps the best indication is to see how much data you currently use on your old plan? See the heading “How do I find out how much data I currently use?” in the article above.
      Hope this helps!

    I have just bought a Garmin Satnav which links to my smartphone with an app called Smartphone Link. This allows live traffic updates, weather etc. Obviously it needs to connect to the internet but I’m not sure how much data it uses. I’d only be using it infrequently.

    I spoke to a Virgin Media rep who told me I’d need unlimited data (expensive tarrif) whereas someone else told me it uses very little data.

    Does anyone have any advice or information on this?

    Thanks.

    1. Ken Lo
      Ken replied:

      Hi Roger,
      Thanks for your comment! My feeling is that a Garmin Satnav will use very little data – it’s only downloading information related to traffic and weather. At most, it’ll only use a couple of megabytes so you don’t need to have an unlimited data tariff.
      As a rule of thumb, most apps will use small amounts of data. Large data consumption only comes when downloading multimedia e.g. photos, videos, music, games, etc.
      Hope this helps!

    Hi Mr Ken,
    Thanks for all the information useful to smartphone user.
    I have recently bought a htc one smart phone. I connect my laptop using the smartphone number to viber to make calls through my laptop. If I make a call using viber through my laptop from home will use any of my data allowances.
    Please respond.

    1. Ken Lo
      Ken replied:

      Hi Alok,

      Thanks for your comment. If you’re tethering via your smartphone (e.g. via wi-fi hotspot or a USB cable) then use of Viber will count towards your download limit. You can avoid this by connecting your laptop to a different wi-fi network (e.g. your home network, a work network, coffee shop network, etc).

      Hope this helps!

    Hi Ken

    Thanks for this great, informative and very helpful article. I currently have a PAYG mobile with Virgin Mobile and am looking at going for their ZTE Blade 3 phone on a monthly contract at £13 per month which includes 500MB of data but was worried about going over the limit (Virgin do let you know when you approach your limit). Having read your article, using the phone at the Virgin Broadband service through the router at home would be a good way forward, leaving the phones own connection for when away from home. How easy is it to set a phone up to work on both? And is it easy to remove automatic checking / updating to save usage?

    1. Ken Lo
      Ken replied:

      Hi Malcolm,

      Thanks for getting in touch. It’s very easy to get your ZTE Blade 3 to use the home broadband connection. As long as you have a wi-fi network set up at home, simply enter the details of the wi-fi network and save it on your new phone. You can do this through the Settings > Wi-Fi menu. Make sure wi-fi is toggled to the “On” position and then tap on the relevant network and enter your wi-fi passcode. Providing you leave the wi-fi turned on, your phone will automatically connect to home broadband whenever it’s available.

      With regards to your applications, open Play Store from the main menu. Tap on the Menu button followed by Settings. Make sure the “Auto-update apps” setting is either set to “Do not auto-update” or “Auto-update over Wi-Fi only”. This ensures your data allowance is preserved for other things.

      Hope this helps!

    Most interesting article, many thanks. Can you confirm that I could, if I purchase an iphone 4, tether to my iPad 2 when in Europe and in Australia. Or do I have to purchase a SIM card for data in the relevant countries. It’s not always convenient to locate a WiFi Hotspot when travelling. Also do Apple permit the use of a ‘foreign’ SIM card to be used in their phones.
    Thanks for any information you can provide.

    1. Ken Lo
      Ken replied:

      Hi Steph,

      You can tether your iPad 2 to an iPhone 4 as long as your network provider has enabled it for your phone. I’d recommend against using your UK SIM card – the data costs will probably be quite high. To reduce the cost, try one of these low cost SIMs for browsing in Europe – alternatively buy a SIM card locally in the country you’re visiting. A foreign SIM card can be used but you’ll need to unlock your iPhone. There’s more details here.

      Hope this helps!

    Very informative. Have just bought my first smartphone (PAYG) and have kept it on WiFi only for data. I don’t make many phone calls but use WiFi hotspots a lot. There is not always a convenient hotspot however. I have now opted in to Vodafone’s Text and Web. I did wonder what 500 MB actually represented but you article has explained it nicely. Many thanks

    Dear Ken found your article interesting and informative. Can you, however, shed any light on why I am incurring “multimedia” charges on my Samsung S2 on Panther 26 with Orange even though ,this month, I have deliberating not used the internet through my mobile phone?

    1. Ken Lo
      Ken replied:

      Hi Michael,

      Thanks for your message. My guess is that these are not data charges – perhaps they’re MMS or picture message charges. On the Orange Panther tariff, MMS messages are charged at 30.6p per message. If you’ve been sending picture messages, this will explain the charge you’re seeing on the bill. If you haven’t, it’s still possible some of your text messages were converted to MMS before they were sent. The Galaxy S2 is prone to do this – when a message goes over a certain length (usually the equivalent of 3 SMS messages), the SMS will be converted into an MMS. You can avoid this by looking out for the “Converting to multimedia message” notification when writing your message.

      Hope this helps,

      Ken

    We’re planning a trip to the UK (from the US) later this month and I’ve had a hard time finding out about tethering in the UK. Your explanation of the rules, who and how, is very clear and useful. In the US, the providers charge extra to use the hotspot function, meaning you pay twice for the same data package and are forced to buy more than any reasonable person would ever use. In addition, they have made the use of third party tethering apps difficult. A ruling last year said Verizon can no longer block the tethering apps, (like PDANet) but there is an uneasy peace. :-)

    Your various articles on mobile subjects in general and in the UK in particular have been a great help. THNX

      Hi Mella,

      Greetings from the UK! :-) I’m afraid I don’t know of any Australian sites, though the information above about what 500MB/1GB correspond to should be the same everywhere. You can apply this information to your cellphone plans in Australia (multiply/divide the figures as required).

    your information is incorrect. 1024 kilobytes make a megabyte, & 1024 of those make a gigabyte.

    1. Ken Lo
      Ken replied:

      Hi there,

      Thanks for the comment! According to the IEC definition, a megabyte is 1000 kilobytes whereas a mebibyte is 1024 kilobytes. See http://en.wikipedia.org/wiki/Mebibyte for more information.

      Unfortunately, usage of 1000 and 1024 is inconsistent within the industry and many people use a megabyte to mean 1024 kilobytes. For the purposes of mobile data, I use the IEC/ISO definition of 1 megabyte = 1000 kilobytes and 1 gigabyte = 1000 megabytes. The reason being that it's better to err on the side of caution and to choose the smaller definition. This should reduce the probability of exceeding your download limit (however your network operator chooses to define it). In practice though, it's probably an academic argument as the probability of data usage being exactly between 1000MB and 1024MB in a given month is quite small.

      Many thanks,

      Ken

      Hi there,

      The SI definition is to have 1000KB in 1MB and 1000MB in 1GB. There are binary prefixes for the 1024 definition – see http://en.wikipedia.org/wiki/Binary_prefix although you’re right in that most people don’t follow this. In terms of data allowances, I think it’s better to use the lower definition just to be safe.

    There are not 1000kb in a mb there are 1024 and there are1024mb in a gb. Computers work in binary which is powers of 2. 1000 is not a power of 2 which is why it is 1024.

    1. Ken Lo
      Ken replied:

      Hi Jim,

      The figures listed for Skype should be fairly representative for other VoIP applications such as Viber! Bear in mind these figures are rough however: it depends on things such as the quality of reception and the bitrate of your phone call.

    I have a question I can't find answered anywhere. Next week (5 and 6 June, 2012), we want to broadcast a live event for 24 hours via the Livestream website. We did this last year for 12 hours and it was brilliant. We did that one from our house, over our own broadband with a dinky webcam. This year we are doing the event from a public place where there is no internet available, so we are considering a dongle. However, we can't work out how much MB's this will use and we do not want to pay a lot. We only want the dongle for one day, so were considering a one-month plan, but the usages they offer seem so low.

    Any suggestions (rather quickly!) what we can do? Thanks!!!

    1. Ken Lo
      Ken replied:

      Hi there,

      It very much depends on the bitrate that you choose to broadcast with! My recommendation is to download a bandwidth metering programme for your PC (e.g. tbbMeter) and then doing a test run for 15-20 minutes. Multiply this up to find out the amount of data that it'll consume. As a rough guide, you could use the figure for Skype video calls in this article, though this isn't reliable as it'll be substantially more if you're doing HD video streaming.

      Hope this helps,

      Ken

    Hi Ken, great article!
    I recently got a Samsung Galaxy Ace from vodafone with 250mb limit. (however, they did say I will have it 'unlimited' for the first three months…) I've only had it for about a week and a half, two weeks top, and they already texted me that I've used up all my allowance! (even though it was supposed to be unlimited!) I was really surprised because all I did was watch a few videos on the 'Workout Trainer' App, update some of the present built-in apps and software (apart from the workout one, I haven't downloaded any new apps to the phone), played with the google maps for 5 minutes and then just used google talk to chat with my friends. I know it's not nothing but I'm still surprised at how quickly this has, apparently, run out. I realise videos and updates might have played a vital part but what about google talk? How much data does it approx use when it's on 24/7? I don't chat that often but even if I exit it, it still stays on so my friends can see me as available or idle. I was convinced this shouldn't take much of the data also as I don't seem to be able to completely switch it off so I'd really appreciate if you could roughly estimate how much data such an IM would use? thanks,
    Mal

    1. Ken Lo
      Ken replied:

      Hi Mal,

      IM shouldn't really use very much data at all – off the top of my head I'd say a maximum of 0.5MB per day even if you're using it very heavily. This assumes you aren't doing things such as sending voice messages, sharing photos and other files through IM, etc. I suspect that the videos and perhaps automatically updating apps could be leading to the heavy data usage. I don't know what the quality of the videos on Workout Trainer are like, but the figures for YouTube videos in the article above should be roughly comparable.

    hi Ken, nice info.

    My wifes plan says this:

    Your Price Plan:
    Your Plan comes with 300 minutes, 500MB mobile internet, 1GB BT Openzone Wi-Fi and unlimited texts, whats the difference between 500mb mobile internet and 1gb BT open zone? i thought it was the same thing.

    1. Ken Lo
      Ken replied:

      Hi there,

      Thanks for your comment! 500MB mobile internet refers to data transferred over 3G whereas 1GB BT Openzone refers to data transferred when connected to a public wi-fi hotspot maintained by BT Openzone. Typically you'll be making use of the 500MB over 3G: the separate 1GB allowance only applies when you deliberately connect to an Openzone hotspot.

      Hope this helps!

    O2 do not automatically charge you a pound a day if you exceed you allowance, the £1 a day charge is for pay and go customers who don’t have any data bolt-on. The allowance with pay monthly is capped, if you reach 80% of your data o2 will send you a text, if you run out of data you will not automatclly be charged, you can add a one off monthly bolt on to keep you going. Otherwise use wi-fi whenever you can, if you get into the habit of connecting to wi-fi this will save you monthly data for when your out and about, 1GB is a lot of data 100,000 web pages roughly.

I'll use my new phone mostly to call/text and I will be editing documents. This is going to be my first smartphone. Can you pease help me work out the data I need? I usually check my emails about 4 times per day, go on facebook 4 times/day and upload 5-10 videos and 20-30 pictures every week. I google information, looking at maybe 50 pages/week. I don't know yet if I'll use any apps, I don't think I'll be interested that much in them (say I'll get 2-5 apps a month on average). I'll also use some sat-nav on it (same 2-3 times per month for 15-30min each). There are plans out there for 100Mb, is that enough or should I get more?

      Hi Flo,

      I'd recommend getting more than 100MB – this may not be enough for your usage. Try a 500MB data plan – this should probably be OK unless you upload a lot of photos and videos. If you upload *a lot* of photos and videos, I'd recommend having a look at Three's all-you-can-eat data plans!

I'm afraid I can't really comment as I don't know the details of the situation nor am I a lawyer, but I'd say the best immediate course of action is to contact Vodafone – I'm surprised that the credit limit on the account was high enough for the bill to be able to reach £9,300. The next step would be Ofcom and consumer rights organisations such as the CAB if there is no luck pleasing your case with Vodafone.

    By popular demand, this post has just been updated with two additional stats:

    1. Many people ask about Skype calling. According to Skype, a typical call has a 50kbit/s bitrate. Our testing on a Galaxy Nexus showed it showed it used around 70kbit/s. A bit rate of 70kbit/s would amount to 0.55MB/minute and hence 500MB = 15 hours.

    2. Many people ask about downloading applications. Applications vary in size quite a lot, but we downloaded the 20 most popular free applications on Android. In total, they came to 121MB. For this reason, we've taken the average app to be 6.1MB in size. Hence 500MB = 80 apps.

    1. Ken Lo
      Ken replied:

      Hi Ankh,

      Thanks for the comment! It's a little known fact that the IEC (International Electrotechnical Commission) standardised on 1MB = 1000KB and 1GB=1000MB in 1998. They also defined some binary prefixes so 1024 bytes = 1 kibibyte, 1024 kibibytes = 1 mebibyte, etc. Though you are correct in saying that usage isn't consistent across the industry so it could actually mean either! I'd say the definition of 1,000 is more useful for this purpose – sticking to 1000 rather than 1024 means you won't inadvertently exceed your download limit!

      You'll get an icon in the notification bar at the top of the screen to show when wi-fi is connected, and also the signal strength. As well as this, the name of the wi-fi network should be displayed on the home screen. If you see this, you can rest assured the internet traffic is going over wi-fi rather than 3G.

      The link between time online and data usage isn't exact but I'd say you should be fine with 500MB/month unless you download/stream music or video or make voice over IP calls (e.g. Skype). The average user consumes around 250MB per month.

I purchased an iPhone 4s from apple, telephoned orange and got them to send me the micro sim. I wonder if could advise, does the iPhone use up more mobile data than an android phone? My normal usage for a month on the htc was just over 100mb I noticed on checking my usage on the iPhone after 3 days that I'd used 70mb. Does it matter that I don't have wifi bt openzone when out and about. Thanks for taking the time to read my comment/questions. SP

      Hi there SPaterson,

      No, there shouldn't be any substantial differences between iPhone/Android – it's more what you do with your phone that counts. So the increased usage is probably due to the fact your iPhone is so new and you're spending a lot of time playing with it and downloading new apps (whereas most people settle down after a while of having the same phone and download fewer apps).

      Hope this helps,

      Ken

    Hi, I hope you can help clear some things up for me as i'm a little confused!

    I got a samsung galaxy on my first ever contract (with orange) last week with 750mb internet usage. ive mainly used the internet for facebook, twitter and the occassional browse but not constantly or for downloading music, watching youtube videos etc. (Luckily) I thought I should see how much i've used and found that i've already used up the allowance and my usage now totals £2.75. I don't think I've used the internet that often to use it all up but what i wanted to check is whether the additional charges are, for example, an additional £1 per day if I continue to use the internet or if i stopped using it until it resets, whether it will add on a £1 a day regardless?

    So in other words, is it £1 per day charge for going over the allowance and therefore a massive charge at the end of the month on top, or a £1 per day extra on top of the normal monthly charge to use the internet if you wanted to once the allowance is reached?

    I'd really appreciate some advice on this, and also how not to go over the allowance again!!
    Many Thanks!

      Hi Kingfisher,

      If it is indeed data usage you're being charged for (I'd be surprised if you managed to go over 750MB in a week with that usage pattern), it's a charge of £1/day for the days which you use the internet. If you turn data off on your Galaxy, there will be no charge.

    Can anyone help , Im on o2 100mins unlimited uk texts for £15.32 per month. When i log onto "My o2" it tells me that my daily limit (Data Usage) is 100MB it also says that i can use data at my standard rate (What is this?) but i will never be charged more than £1 per day. Yesterday i deleted all my APPS, turned off background Data Usage in the settings and finally turned off my phone. When I checked at 11pm last night I had used 1.4MB of Data and had been charged 85p. Today I have already been charged another 85p (Phone is turned off exept when checking data) my Bill for last month was £52 ? Does this sound excessive. The phone is an LG Optimus. If i am going to be charge 85p (+vat I expect) for not using anything then why is this offered as a £15p/m tarriff?

      Hi there,

      It sounds like you don't have a data package with your contract which explains why you are being charged up to £1/day for internet usage. Best thing to do would be to call up O2 and switch to a tariff with inclusive internet!

    my contract is supposed to be £20 a month but for the last 3 months it has come in at £60. I rang vodafone up to ask why it was this price and they said my blackberry makes an update every night at 12 and becuase internet wasnt a part of my contract i was having to pay 89p every time. I was not made aware of this when i brought the phone..am i entitled to ask for the money back?

      Hi Robert,

      I'm afraid I'm no expert on consumer law – sorry. Vodafone have a valid argument in that your phone was using data services and so you should be charged. You may also have an argument in that you never authorised the use of the data service and that you were unaware of the use. My suggestion is to disable the automatic update at midnight to prevent further charges – whether you want to go further and to dispute the additional £40 worth of charges is something I cannot advise on!

    Thanks for the kind words! It shouldn't do no: GPS positioning alone shouldn't use up any data – that said if the application does things such as automatically downloading maps of your current location that would eat into your allowance.

    Hi Ken, I've recently got a contract phone, £20 per month with 250 mb. My monthly bill was over £41 last month but I barely use it. I do receive about 25 emails a day but have only ever replied to one and have looked at FaceBook and internet a couple of times. Not sure why my bill is so high, perhaps I have something switched on that is using up all my mbs? I checked my usage this month after one week and had already used up my allowance!

    Michelle

    1. Ken Lo
      Ken replied:

      Hi Michelle,

      Sorry to hear about the problems you're having. My first recommendation is to make sure you use wi-fi at home: this should cut your data usage substantially. Secondly, monitor your data usage using something like 3G Watchdog (for Android devices). You can set up this application to alter you or automatically disable your internet connectivity when you reach a certain point (e.g. 225mb). Hopefully this application will help you to work out why you exceeded your data allowance last month: for example it could be that you've downloaded a software update or several large applications from App Store/Android Market over 3G.

    I just got my new phone and i have 750mb data allowance a month,

    Am i right in thinking this will be ok to use Facebook daily, read the few emails i get and occasionally check cinema times?

    I have wifi in my home so at home it will connect to that. But out and about will it eat into my allowance as its a smart phone?I.e, be connected to the internet all the time, or will i have to keep turning it off and on again?

      Hi Meme,

      Yes you can… if those are the things you use your smartphone for, and especially with wifi at home, no need to worry about a 750mb data allowance. Things like online radio, YouTube, music downloads, etc. are the only things you really need to worry about – those are the things which eat up your data allowance very quickly!

    Yeh really helpful, good to get some figures actually in front of you and in black and white.

    I'm planning on upgrading to an I-Phone with 750mb allowance but just need to make sure im not getting conned. My current contract for my vivas is consistantly high but i reckon this may be down to the fact that no data charges are even considered in my contract, and standard data charges are given? I only really use the internet for facebook and football scores, so i'm slightly puzzled as to how my bills are often quite expensive.

    Thanks, Stu

      Ken replied:

      Hi,

      If you don't have an inclusive data allowance in your package this would mean you're paying standard rates for data – it could be as high as £4/MB in some cases – or sometimes £1 or £2 per day depending on your tariff. If you've got an inclusive data allowance, you shouldn't have to worry about data costs providing you keep within the 750mb allowance :)

    Hi Ken. Really helpful articale.
    would like to bounce a few questions off you if that is ok. My 14 year old daughter has a SIM ONLY Orange 12 month contract for £10 a month giving 300 minutes plus UL text per month, She wants to buty a Blackberry Curve (has an LG350 currently) but i am a little out of my depth re data (i have a company iphone so do not get any costs). So after speaking to Orange i am not able to change her current contract for another 7 months(seemed like a good idea at the time). The only option i think i have is to add a £5 per month 500MB bundle to her current contract and buy a Blackberry. thats the story so far the questions i have are. Can BBM only be sent to other Blackberry users and are they FOC. She is an strong user of TEXT messaging but i do not believe that BBM is a full replacement of this. In the house she can use the WiFi FOC but will stream data for Facebook, tumblr Utube and Skype when out an about. After reading your article FB is ok however Skype and Utube are an issue due to data use. can you confirm all this for me please? any advise is greatly recieved. Thanks Bill

    1. Ken Lo
      Ken replied:

      Hi Bill,

      Thanks for your comment. Adding a data bundle sounds like a reasonable solution – however make sure it's a BlackBerry data bundle. BlackBerry devices cannot be used with any old data bundle – more info here.

      BBM messages can only be exchanged between BlackBerry users. They are free of charge. SMS messaging is still important for contacting friends who don't use BlackBerry. An alternative application called WhatsApp is similar to BBM but can be used on Android and iPhone devices too.

      And you are correct :) Skype and YouTube will use up 3G data allowances *very* quickly; but Facebook and Tumblr should be fine. If Skype and YouTube are used over wi-fi, it doesn't count towards the 500MB limit on 3G.

      Hope this helps,

    Would just like to ask, i have been thinking about getting the i phone 4 on a 3 mobile contract and unsure if 500mb would be enough. as im going to uni in september i can easily connect to the wi-fi on campus and also connect to the wi-fi at home and therefore not use up and of my 500mb a month. The only places i would use my MB up would be on a bus or out and about where wi-fi isnt available. Is this correct? And do you think in my case, it would be wise to go for 500mb?

    Thanks a lot

    1. Ken Lo
      Ken replied:

      Hi Gemma,

      Thanks for the kind words! In general, 500MB per month should be plenty providing you don't download/stream music or video over 3G – you'll need to save those things for when you have wi-fi on campus or at home. Things like Facebook, Google Maps and browsing the web alone shouldn't take you anywhere close to 500MB so I would say it's fine! That said, it might be worth looking at The One Plan if you're looking for some reassurance with no download limits.

      Ken replied:

      Hi Billie,

      Yes – your phone will have an option to turn off "mobile network data" or something. Turn this off if you are billed for mobile internet – typically your phone will automatically switch to 3G for data if it loses the wi-fi connection (e.g. you stray outside the range of the wi-fi hotspot, connection temporarily lost due to microwave interference, etc.)

      Hi Susan,

      Facebook/Twitter/E-mail probably will use some data even when you're not using it (e.g. your phone might automatically download new e-mails). That said, I really wouldn't worry about Facebook, Twitter or E-mail taking you anywhere close to your download limit if you only use your smartphone for these things. It's only really things like music, video, downloads, radio, Skype, etc. where you need to worry about download limits.

    Hi Ken

    Great article and very helpful (even to an ex-IT guy!)
    Having worked in the industry for many years I'm appalled that there is still confusion about GB as Giga Bytes and GB as Giga Bits/Sec. I'm never really sure myself when the mobile providers (or general ISPs for that matter) quote GB whether they are talking about bits or bytes!
    What's your understanding?

    Also, on a related subject, many mobile Internet users can log into office systems at their place of work using Citrix (or GoToMyPC). Since these systems only transfer changes in the bit patterns of the office screen (or it's pseudo version in a server) down the line and mouse movements, etc up the line wouldn't it be cheaper to access the Internet this way (always assuming their company policise allow them to do this)?
    What do you think?

      Given the overhead of creating the session – I strongly suspect this would be much more bandwidth intensive.

    Hi
    Thanks for this article. I am a bit of a technoilliterate and it has been hugely helpful in explaining some basic terms. I want to upgrade my phone to an iphone 4. However, I want a £35 tariff that I currently am on and I really don't want to pay very much for the phone. I notice that Three is offering a 1GB deal on an iphone 4 for £35 a month and only charging £35 for the phone which looks pretty good to me. I wonder if there is a catch – what do you think?
    Also if i download applications such as games and have them stored on my phone – will I use up any MB's when I play games etc.. etc..

      Hi Anna,

      Thanks for your comment! For a review of Three's £35 tariff (called The One Plan), see our review here.

      With regards to games… *normally* they don't use very much data. Some games will use data but this varies depending on the game and what kind of features it incorporates. However, I would say that you most certainly shouldn't worry about data usage from playing games stored on the phone – it won't eat up a significant amount of data. Probably 1MB tops.

    1megabyte is actually 1024 kilobytes. If you didnt know that then i am skeptical about what else you may be wrong about in this article

    1. Ken Lo
      Ken replied:

      Hi Connor,

      Technically a megabyte is 1000 kilobytes whereas a mebibyte is 1024 kilobytes. More info at http://en.wikipedia.org/wiki/Mebibyte. However, usage is inconsistent within the industry and many people use a megabyte to mean 1024 kilobytes. For the purposes of mobile data, we suggest using the ISO definition of 1 megabyte = 1000 kilobytes and 1 gigabyte = 1000 megabytes. The reason being that because it's ambiguous what your mobile operator actually means, confining yourself to the lower limit will ensure that you don't exceed your download allowance & incur extra charges. In practice, this is mostly an academic argument as the probability of data usage being between 1000MB and 1024MB in a given month is very small.

      500MB should suffice for Facebook and instant messaging applications. If you're looking to listen to online radio or watch online video, it might be worth considering the all-you-can-eat package instead.

      Hi,

      For more info on mobile broadband & using The One Plan for mobile broadband see my write-up here.

      On the whole, home broadband will offer a much better speed – you will probably find it cheaper to take line rental at roughly £11/month plus a basic broadband package at ~£7.50/month. This adds up to £18.50/month which compares well with mobile broadband given you'll get much better speeds & download limits with home broadband. The One Plan is £25/month.

    I may sound really dumb by this but my partners sister has the HTC wildfire and her phone often shows a little 3g symbol near her signal bars (she is on tmobile). I myself am on 3 but get the letter 'R' showing, and as far as I am aware have the data roaming settings turned off. How do I know when my phone is connected to the mobile internet? (how do i do this even?) As I am paying monthly for threes text 500 (500 mins, 5000 text, 1gb internet), so far I have only connected to my home WI-Fi but am now worried that i'll get charged a lot extra due to this 'R' symbol which I am presuming means roaming, yet as mentioned I have turned off the data roaming facilities. I have downloaded various free Aps, visited websites using the browser and have my two email accounts setup, as far as i know using wifi only. I have the HTC Desire. Help! – thanks in advanced!

      Ken replied:

      Hi Marie-Louise,

      Thanks for your comment. I'm unsure about the exact reason – but does the R symbol correspond to the fact you're roaming on Orange 2G? Although they've begun turning it off in some areas, there are still many places where it's active.

    when it says 500mb mobile web does it mean that you can have unlimited time on the internet until the 500mb runs out or you have to pay for the internet ?

    1. Ken Lo
      Ken replied:

      Hi Tony,

      Mobile web is charged by the amount you download rather than the time you spend on it. So the amount of time you spend on the internet doesn't directly affect your data usage: only what you do in that time.

    What would be really interesting is to correlate speed of downloads along with data limits. All the major networks 'throttle' their networks according to the price you pay, although none of them publicize their actual or even theoretical 'Upto' speeds.

  139. Mark said:

    Hi. Can someone help me. I have just got the new I phone 4 and within the network section there are options to enable 3G, mobile data and data roaming. Can someone tell me what these are and the differences between them?

    Thanks

    1. Ken Lo
      Ken replied:

      Hi Mark,
      The 3G toggle determines whether you can use 3G/HSDPA high-speed data on your phone. This sometimes uses more power than 2G but you'll get much better download speeds.
      The mobile data toggle determines whether you can use data over the mobile network at all – I'd turn this off only if you were on a tariff without inclusive data (otherwise you can still use wi-fi networks)
      Finally, the data roaming toggle determines whether your iPhone can connect to the mobile networks whilst abroad. Be aware that this will often cost ~£6/MB so it's strongly recommended you have this OFF.
      Hope this helps,
      Ken

    Thanks for the very useful guide. I'm a low user on 02's Simplicity 100MB a month tariff. You didn't mention using Google Maps as a satnav – how much data would that consume on, say, a one hour journey?

    1. Ken Lo
      Ken replied:

      Hi Gerry,

      Thanks for your question. As I understand it, Google Maps GPS navigation on Android downloads road information in vector format (e.g. it just downloads the route and information on where the roads are, rather than image files of the map itself like some older version of Google Maps do. Hence I wouldn't expect it to use very much data – maybe a rough on-the-order-of estimate 0.1MB per mile. You could download the 3G Watchdog application for your phone, run it on a journey and let us know what you find out though!

    Great article. I just got a new blackberry with a new network, it has a 1gb data allowance. My old BB had BB unlimited, but I only use my mobile for emails and occasional facebook/twitter. I have connected to my home wi-fi and the wi-fi icon is on my mobile. I decided to download the apps I used on my old BB, had a few emails and tried a bit of web browsing, and afterwards I checked my allowance and it says I have used my whole 1gb in 1 day, even though I have been at home and connected to my home wi-fi. I tried calling the network up but after being on hold for 15 minutes and having my call answered by someone who couldn't understand my query, I gave up. Is it correct that my allowance is all used up in one day while connected to my home wi-fi?

    1. Ken Lo
      Ken replied:

      Hi Jen,

      This is very strange: data through your home wi-fi connection won't count towards your 1GB data allowance. The data allowance applies only to downloads over the mobile network. Please do let us know if you find out what caused your entire download allowance to be used in a day: I don't have any ideas at the moment.

      Hi Paul,

      Unfortunately it does yep. You should assume that streaming radio uses roughly the same amount of data as downloading music – around 1MB per minute of online radio.

      Online radio is encoded in 128kbit/s = 16kbyte/sec = 960kbytes/min = approx. 1MB/minute

      Hard to tell as applications can vary in size a lot – Angry Birds is 17MB for example whilst many other apps are <1MB. Data downloaded over a wifi network doesn't count towards your 500MB data limit so you're in luck!

    I've just upgraded to my first smartphone, a BlackBerry with 500 MB of data usage. Your table suggests this equates to anywhere up to 500,000 emails a month, but does this mean both incoming (which I can't control) and outgoing mail (which I can)? And if I receive a mail with an attachment but don't open the attachment, does that save some capacity? Sorry to be so ignorant – I'm new at this game!
    thanks

    1. Ken Lo
      Ken replied:

      Hi Susan,

      Yes, this refers to both incoming and outgoing mail. However, chances are your phone won't automatically download every single e-mail – spam e-mail will probably be in a different folder for example and won't automatically be downloaded onto your phone. With regards to the attachment, the attachment isn't normally downloaded unless you open it. Of course, your mileage may vary depending on how your phone & e-mail application is configured.

      Hope this helps,

      Ken

      Hi Claire,

      Yes, radio station apps will typically stream audio through the internet connection and this will count towards your download limit. There is a great discussion of radio stations & data usage at James Cridland’s blog. In short, 2GB would allow you to listen to a 64kbps stream for 64 hours a month.

    1. Ken Lo

      Hi Goldie,

      Sorry to hear about the huge bill… but 13 songs alone would not have taken her over the 1GB allowance. One song is roughly 4MB to 5MB so I would expect 13 songs to weigh in at around 65MB absolute tops – a long way from 1,000MB (1GB). Is this definitely a data charge as opposed to an expensive phone call?

    1. Ken Lo
      Ken replied:

      Hi Robert,

      I've had a quick Google around – it looks like TuneIn radio is an internet radio application so the answer is yes it would. The data usage would be in the order of that for downloading music tracks (listed above)… maybe slightly less depending on the quality of the streams that TuneIn uses. Bear in mind that when you're at home and connected to wi-fi, it doesn't count towards your download allowance… only when you're on 3G.

    1. Ken Lo
      Ken replied:

      Hi Floss,

      With a smartphone such as the HTC Wildfire, you'll need an internet package to be able to use most of the features on the phone. For example reading your e-mail, updating Facebook, downloading and using applications, using the maps functionality and the turn-by-turn GPS navigation which is included in your phone. So even if you never open a web browser, you'll still need an internet package.

      If you really don't use any of those functions, you could disable internet connectivity on the device but you should be aware that most of the functions which set the Wildfire apart from a cheaper handset will not work correctly.

      Hope this helps

    I have a 1GB data allowance on my mobile plan and have never gone over it until last month. I use my home internet for most things, only use my phone occasionally for checking bank balance, maps (very rarely), checking sports scores, etc… Youtube and facebook are free (not counted towards the data allowance) and I dont download apps (at least not in the past 4 months) or use skype. I dont use email on my phone, dont stream radio…

    Could anybody tell me how i could possibly have used over 400mb in one go, on three seperate occassions?? I'm adamant that there is no way it happened but my phone company reckons it did. I wasn't doing anything new or unusual so i dont understand how this is possible..

    In the 3 weeks since my last bill i have been tracking my usage closely and only used a total of 140mb. Is it possible the phone company screwed up? And any ideas on how i could prove that i didnt?

    Any insight would be greatly appreciated. Thanks.

    1. Ken Lo
      Ken replied:

      Hi Jimmy,

      Sorry to hear about your situation but unfortunately it would be difficult for you to prove so now afterwards. If you've got an Android phone, download the "3G Watchdog" app (a similar app should be available for other platforms). It will allow you to view information on how much data you're using from your phone. You can set it to notify you when you reach a certain threshold, compare the stats from that with your networks stats and diagnose any problemaic apps.

      My inclination is that it might be to do with your YouTube usage… as far as I'm aware all networks count YouTube usage towards the data allowance and it's possible this could have pushed you over the 1GB allowance. And whilst Three allow free Facebook but this is only to 0.facebook.com… all other Facebook usage is metered. However, Facebook usage alone is unlikely to use up very much data.

      Hope this helps,

        Hi twilight,

        Sorry for the slow response… I was taking some time off for Christmas! Skype is a real bandwidth-hog. I'm not sure what the bitrate of Skype calls (and I've struggled to find a definitive answer anywhere). The audio quality of Skype calls is lower than that of music but bear in mind that during a phone call you are transmitting audio data both from the internet and to the internet. As a good approximation, you should consider Skype usage to be about the same as downloading music (maybe a bit less). My quick guesstimate is that an hour of Skype calls would use about 100MB so using Skype for even 10 hours a month would use up the entirety of your download allowance. This probably explains why you ran out of internet so quickly.

        Bear in mind that using Skype is also against the terms of use of most UK networks. The only exception is Three.

      No. Data downloaded over the wi-fi connection doesn't go through your network operator at all. There are no charges for using wi-fi from your phone except from the normal charges you incur for your home broadband service. If you use a public wi-fi hotspot, same again… no charges except from any charges which might be charged by the hotspot provider.

        I work at Three and the reason for the change is not that the limits have changed but instead a decision to stop using the word unlimited when it is subject to a fair use policy.

    And if ou know the answer to this it would be appreciated too :) … How much does Internet radio use

    I have 1gb internet usage and i frequently – stream Youtube, watch tv via BBC i-Player, stream worldwide internet radio, use google maps, google street maps, check google for quick answers, wikipedia, about 5 push emails per day, download music tracks, heck oi networks in the day time and once tethered (use mobile as a modem) for about 5 hours and didnt go over.

    I’d recommend 250mb for light users, 500mb for regular and 1gb for heavy users. if you’re unsure just ask before you sit down and agree to anything.

    500mb gets refreshed every month. general internet and facebook will be fine. be carefull with games you download as 1. you have to pay for the actual game itself. If its £3.00, add £3 onto the bill. if the game is free thats ace! 2. Downloading a game will use more data than normal because your downloading it to your phone. 3. some games you can download BUT they connect to the internet to work, even tho you’ve downloaded it you wont physically have it. Just be carefull, read everything before you click on something.

    Nothing wrong with 500mb on an i phone 4 at all. If there was, a mobile provider wouldnt give you an i phone with 500mb of internet in certain package (usually occasional to frequent users) Ive worked in a phone store for 2years.

    bbc website is light usage. internet radio is streaming. depends on how often you’d be doing it. to be safe you’d need 500mb. you’re network should provide 500mb, 750mb or 1gb depending on your provider.

    Guess i cant be seen as being ‘too’ helpful lol.

      Thanks for your contributions – we really appreciate it! Yes there is definitely a lack of knowledge about download limits here in the UK and I commend you for outlining to your customers what they mean. It's a shame that not all mobile phone salesmen do the same!

    I once worked in a store where 1GB (1024mb) package was available for £5 ($8) on top of a monthly contract but many people didnt want it as facebook and youtube wasn't the "in thing". We pitched it to most customers because it was part of our job. Low and behold a customer ran up an EXTRA £75 ($119) on their bill for about 300mb of usage because they didnt want the add-on. They came in to complain but the customer was responsible for their own usage.

  181. Das Phone Wunderkind said:

    I would just like to add that as a mobile phone sales person, i have (for the past 2years) broken down what 500mb, 750mb 1gb internet usage actually entails then relating it to that customer asking what they may use the internet for so they know what they can/cant use and what they will be limited to. I too find it strange when instore colleagues and other phone store staff dont know this info. I found it out off my own back, we've had this product in the U.K for about 2 years.

    Hi – thanks for the very informative article. Currently I spend a fortune monthly on internet usage and all i actually do is browse facebook. I never spend long on there and can't actually get much of the app up – it's just really status updates etc. I also have 300 mins and unlimited texts in my contract and i stay within these limits. Now i want to go over to an iphone and am wondering if 500mb will be enough. like i say – all i do is browse the odd page or two of facebook a few times a day. i very occasionally look up something on google. that's it. at the minute it's extortionate the extra i pay so i want to make sure i'll be covered. any ideas anyone?

    1. Ken Lo
      Ken replied:

      Hi Aileen,

      Yep – 500mb should be plenty for you if you only check Facebook and use Google occasionally. It's usually pretty difficult to exceed 500MB unless you download music, videos or a lot of photos.

    I bought a prepaid vodafone internet package that allowed me up to 1GB over the course of 90 days. I bought it 2 weeks ago and it told me I had no more time left and had used my GB. I am abroad in Spain so I Skype with my parents a lot and watch TV on the internet and do research, but it seemed a little ridiculous. I went to ask the people at the department store I bought it at and they didnt really have any idea. Is it possible its incorrect or did I go through my 1GB using roughly 5 hours of skype and 10 hours of television and more hours of internet? Thanks for all the info!

    1. Ken Lo
      Ken replied:

      Hi Annsley,

      Yep – if you're doing phone calls and television, you'll use up your data allowance really, really quickly. See the guide above, and our article about watching online video from your mobile.

      I must say though… if you're abroad in Spain I would have thought that your internet allowance probably wouldn't cover data usage in Spain anyway.

    Thanks Ken – this is really useful – actually very reassuring as starting a new contract and was told about the 1GB limit which was concerning at the time, but now it's not!!

  185. simon said:

    I dont seem to have any mention of limits on my contract with orange but when I returned from a US trip recently i saw my bill mentioned £3.80 for internet data usage. I queried this & said I have never connected to the internet via a mobile phone. they told me I may have accidentlly pressed a wrong button! And this resulted in a £3.80 fee? YIKES! ( they did refund the money)
    How can anyone afford to do internet stuff by mobile? It could cost me £150 to check my emails!
    I have a Nokia 6700 BTW, maybe smart phones are much cheaper to connect?

    1. Ken Lo
      Ken replied:

      Hi Simon,

      The chances are you probably do have fair usage limits on your contract but this is not why you've been charged this time. It's more likely that you've been charged for roaming internet which costs a fortune. We've got some more info over here and info about how to stop it happening.

  186. Camel said:

    Hi, thanks, this is very helpful. But I have one more question… How does 1GB correspond to skype calls? I.e. How much of my 1GB allowance is used in a one-hour skype call? And is this different depending on whether I am using WiFi connection or a 3G connection? Thanks very much!

    1. Andriy replied:

      It's about 2 hrs of Skype = 500MB of your data

      1. Ken Lo
        Ken replied:

        Hi Andriy,

        2 hours of video calling on Skype will use up approximately 500MB. Voice calling should use up a lot less :)

  188. Drake said:

    Hi, I'm only 17 (new to tariff phones and just bought one last friday) and my dad pays for my tariff but i'm scared to use my internet cos i might over use it. My tariff is 300minutes calls, unlimited texts and unlimited internet (but it came up to be 500mb monthly). Now, i've read what it says above but i'm still a little confused about the 500mb internet part. Is this means i can use my Facebook/Internet/Games i downloaded, for 'free' for a month (everyday) and when my first monthly tariff bill is payed i can use it again for another month for free and so on?

    Plese could somebody reply to this! Thanks!

      You can use up to 500mb of data every month,check list above for what you can downlaod.

  189. mazel said:

    Thanks fr ur article. I have few questions. I just got a new blackberry 8520 contract, the data usage allowance is 500mb.

    If I turn off Mobile O2 Network in my Manage Connection settings and turn on wifi instead, and use wifi to browse and download webpages, will that also contribute to my monthly 500mb allowance ?

    Are there ways in which I could track my internet usage ? like, just to check how much MBs do I have left to use?

    thanks much.
    cheers

    1. Ken Lo
      Ken replied:

      Hi mazel,

      If you connect through your wi-fi network, it won't count towards your 500MB download allowance. With regards to your second question, you can find out by logging in to the "My O2" section of the O2 website.

      Hope this helps,

      Ken

      In your third question, there is a app you can download called 3G Watchdog, it lets you know how much you are using.

      Hope this helps.

    When you actually watching the stream video you downloaded, will it separately use up your free GB for downloading and then for watching it?

    1. Ken Lo
      Ken replied:

      When we say that "download", simply think of that as "data transferred". If you're streaming video from the internet, data is being transferred from the internet onto your mobile phone. This counts towards your data usage limit regardless of whether you are streaming the video or saving it to memory.

  191. Caley said:

    Thank you very much for this! I had no idea that when it says 'unlimited' there is still a secret limit on usage….i was going to take a more expensive contract as i thought 'unlimited' meant just that. I definitely wont be doing that now! Cheers for really good article!

  192. Internet Noob said:

    ok, i hate to be so dumb and i know that it sais that with 1GB corrisponds to 3,000 rich web pages. but i am not downloading the web pages so why 3,000, is it a restriction or something?

    1. Ken Lo
      Ken replied:

      Hi,

      When you browse a web page your computer/phone must download it before it can view it.

    2. Hjalle replied:

      Theoretically whenever you load a web page you 'download' the content so that you can see it, so you are downloading it. I hope i helped a little bit

    500MB a month will be terrible for the iphone 4 i think! does it affect if u want to download apps

    1. michael replied:

      download them on itunes on your PC then sync them onto iphone would do the trick

    2. jase replied:

      or you could use a wi-fi connection to do all of your downloading and streaming and save your 3G for when you cant remember whats-his-faces name from that film you saw and get that strange urge to find out that instant…. tehe :)

      1. Roger replied:

        yh i know what you mean – that always happens! a lot of the time, if you are around a town or city, you can usually connect to a nearby wi-fi hotspot in a coffee shop or something for 'emergency googling' :D
