A 8GB data plan will allow you to browse the internet for around 96 hours, to stream 1,600 songs or to watch 16 hours 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 8GB of data, prices currently start from £7/month in the UK. With your 8GB of data, you'll be able to browse the internet for approximately 96 hours per month, to stream 1,600 songs online or to watch 16 hours of online video in standard definition.

In this article, we'll discuss what you can do with 8GB of data and how long you can expect your 8GB allowance to last for. We'll also discuss 8GB data plans, where you can find one in the UK and how much you can expect to pay.

How Much Is 8GB Data?

In the UK, a number of mobile networks currently offer 8GB data plans. There's a choice of 6 mobile networks if you're looking for a Pay Monthly SIM card, and a further choice of 2 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 8GB of data from £7.00/month. The following table shows a list of currently available deals:

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 8GB of data from £10.00/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 8GB of data per month:

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 8GB 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:

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 8GB 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 8GB of data:

Activity8GB data is equal to...
Accessing web pages4,800 web pages (approx 96 hours browsing)
Basic e-mail/instant message2,800,000 messages
Rich e-mail/IM (with attachments)16,000 messages
Downloading or streaming music1,600 songs
Downloading or streaming video (SD)16 hours
Downloading or streaming video (HD)4 hours
Skype voice call240 hours
Skype video call32 hours
Listening to online radio128 hours
Downloading or updating apps200 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 means a 8GB data allowance should comfortably cover the average UK consumer's monthly data usage.

    If your using any social medias like it ig FB etc. Then you should make sure when you are watching videos you are putting the resolution to sd and don’t open social medias that much also if you are using zoom that may be why because zoom takes minimum 1gig per hour on a 1on1 call and minimum 2 gigs per hour on group meetings

    I’m burning up 1gig+ of data per day on my ipad, how is this possible? i purchase load for my tablet and use up only one gig in the eight days it lasts, and I use the tab for the same reasons as the ipad.

    • Turn off background app refresh, in fact turn everything off that talks to the internet in the background. Also watch and upload HD videos on WIFI and not mobile data networks. Also do not update your apps while on mobile network, 5 app updates will use up 1G per day no problem!
