What is mobile data?
Whenever you use the internet on your mobile or tablet, you’re using data. Most of our tariffs come with a monthly data allowance in megabytes (MB) or gigabytes (GB). Once you’ve used your allowance, you have three options:
One way to make your allowance go further is to use wifi whenever you can. That way, you save your data allowance for when you're on the move. We've got 1000s of free hotspots across the UK where you can use as much O2 Wifi as you want – without paying a penny. Find your nearest O2 Wifi hotspot.
If you need more data, you can upgrade your tariff or get a one-off Bolt On in My O2.
Where does my data go?
Downloading films or TV shows eats the most data. Sending and receiving emails with large attachments can use just as much. Here are a few examples, to give you a rough idea.
We don't recommend using your phone as a personal hotspot. Sims on standard mobile tariffs are designed for calls, texts and general use, like daily browsing. They're not made for being used as or in a mobile broadband device, as this eats up a lot of data.

Keeping up to date with your data usage
You can download the My O2 app. Sign in, go to My Allowances and choose Data. You'll see a breakdown of all the data you've used and what's left. Alternatively, sign in to your My O2 account online.
To help you stay on top of your data usage, we'll text you when you've reached 80% of your allowance and again when you've reached 100%. Once you’ve used up your monthly allowance, you’ll need to buy more to get back online.
You could buy a one off Bolt On through My O2 to keep you going until your next bill date. Or increase your monthly data package so you don’t have to worry about running out of data again.
Top tips for saving data
Nothing can be more frustrating than getting a top-up of data each month, only to see it disappear within days, or sometimes hours. We’ve looked at all the daily data eaters and come up with some suggestions around how to look after that precious mobile data of yours.
