A 500MB data plan will allow you to browse the internet for around 6 hours, to stream 100 songs or to watch 1 hour of standard-definition video.

Nowadays, the key difference between mobile phone price plans is how many gigabytes of data it comes with.

If you're looking for a mobile phone plan with 500MB of data, prices currently start from £4/month in the UK. With your 500MB of data, you'll be able to browse the internet for approximately 6 hours per month, to stream 100 songs online or to watch 1 hour of online video in standard definition.

In this article, we'll discuss what you can do with 500MB of data and how long you can expect your 500MB allowance to last for. We'll also discuss 500MB data plans, where you can find one in the UK and how much you can expect to pay.

How Much Is 500MB Data?

In the UK, a number of mobile networks currently offer 500MB data plans. There's a choice of 5 mobile networks if you're looking for a Pay Monthly SIM card, and a further choice of 5 networks if you're looking for a more flexible Pay As You Go bundle.

Pay Monthly SIM Cards

If you're looking for the lowest possible prices, you can get a Pay Monthly SIM card with 500MB of data from £3.99/month. The following table shows a list of currently available deals:

iD Mobile150Unlimited500MB£3.99
1 month
ASDA Mobile200Unlimited500MB£5.00

Virgin Mobile500Unlimited500MB£6.00

Contract lengths will vary when taking a Pay Monthly contract. You'll normally need to undergo a credit check when taking out a Pay Monthly contract.

Pay As You Go SIM Cards

If you're looking for a bit of extra flexibility, a Pay As You Go bundle allows you to have this with 500MB of data from £5.00/month. There's no commitment to renewing your bundle every month. You can also increase or decrease your data allowance at the end of each month if you find you're on a plan with the wrong amount of data.

The following table shows Pay As You Go bundles with 500MB of data per month:

ASDA Mobile200Unlimited500MB£5.00
iD Mobile150Unlimited500MB£5.00
Tesco Mobile250500500MB£7.50
There's no need to undergo a credit check when taking a Pay As You Go bundle. It's normally possible to order a free Pay As You Go SIM card: you'll then simply need to top it up with credit to get started.


Instead of choosing a 500MB data plan, it may sometimes make sense to choose a plan with more data. This is especially the case when special offers and promotion are available: you might be able to get a larger allowance of data for the same or for a very similar price:

Amount of DataPay MonthlyPay As You Go
250MB Data£13.00 £9 more£5.00
500MB Data£3.99£5.00
1GB Data£5.00 £1 more£7.50 £2.5 more
2GB Data£5.00 £1 more£7.00 £2 more
3GB Data£7.00 £3 more£10.00 £5 more
4GB Data£8.00 £4 more£10.00 £5 more
6GB Data£10.00 £6 more£10.00 £5 more

20GB Data£14.00 £10 more£15.00 £10 more
40GB Data£23.00 £19 more£20.00 £15 more
100GB Data£15.00 £11 more-
Unlimited Data£18.00 £14 more£25.00 £20 more

Some price plans include a data rollover feature giving you a second opportunity to use your data allowance. Alternatively, an unlimited data plan could also be worth thinking about if you'd like a worry-free plan where you never need to think about how much data you're using.

How Long Does 500MB Of Data Last?

When figuring out how much data you need, it's important to think about your own individual usage requirements.

If you choose a plan with too much data, you could be overpaying for lots of data that you don't actually use. On the other hand, choosing a plan with too little data could mean being cut-off from the internet in the middle of the month.

The following table gives you an approximate guide to what you can do with 500MB of data:

Activity500MB data is equal to...
Accessing web pages300 web pages (approx 6 hours browsing)
Basic e-mail/instant message175,000 messages
Rich e-mail/IM (with attachments)1,000 messages
Downloading or streaming music100 songs
Downloading or streaming video (SD)1 hour
Downloading or streaming video (HD)15 minutes
Skype voice call15 hours
Skype video call2 hours
Listening to online radio8 hours
Downloading or updating apps13 apps

We've made a number of assumptions in coming to these numbers. You can read about these in more detail here.

As of 2019, the average UK consumer uses around 3GB of mobile data each month. This has been growing rapidly in the past few years (e.g. it was only 1.9GB in 2017 and 0.2GB in 2012). This makes a 500MB data allowance is a little smaller than average. However, if you find yourself mainly using a wi-fi connection when at home or at work, it's possible you won't need as much data as the average consumer.

  • Hi Ken…I rue the day I introduced my mother to words with friends. She is addicted and plays hours everyday. I have her on our shared plan, 3 phones with 60 gigs. Should be plenty but several times she has used up our gigs(I refuse to buy additional) my husband & I can & do use wi fi when at home or available. My question is how many hours of game play is one gig? Can’t find that info anywhere. I’m about to switch her to her own plan & she can deal with it. Thanks.

    • Hi Kyleen,
      Unfortunately, there isn’t a simple answer to this as it depends very much on the game! The best way to find out is by following the instructions here. That should allow you to see a breakdown of how much data each application is using, and how much is being used by Words with Friends. You can then divide that the number of hours she spends playing the game, to get an approximate “data usage per hour” if required. I must say, however, I’m incredibly doubtful that Words With Friends would use 60GB per month – it’s possible you’ll find another culprit when you look!

  • Hi Ken,
    I have just bought my first smart phone (I’m a very old girl!) and a monthly SIM card, both online. The plan said 2GB data – I didn’t have the faintest idea what that actually meant! But now I do. I thought about going into my local phone shop but couldn’t face the pitying looks of the staff.
    But now I don’t have to thanks to your wonderfully clear explanation. Thank you, Ken!
