Buying an Add-on.
You’ll be prompted to get an Add-on after you’ve topped up but you can get one at any time. It doesn’t cost extra to get an Add-on, you just use the top-up credit and choose the Add-on that will be most useful for you.
There are two ways of getting an Add-on:
Check your balance & Add-on allowances.
If you're not sure when you'll need to top-up again, you can find out by checking your balance. Checking your balance will let you know how much credit you have in your account. If you're using an Add-on, you'll be able to find out how much of your allowance you have left and when the Add-on is due to expire.
Check your balance on your phone.
You can find out your remaining balance by visiting your My3 account for free from your phone:
You can also access your My3 account from your computer. You’ll need to register your My3 account if you haven’t already done so, then:
Or you can download the Three App for iPhone or Android phone for instant access to your My3 account.
All-you-can-eat data on Pay As You Go.
If you want all-you-can-eat data on our current Pay As You Go tariff, you'll need to buy an All in One Add-on. It gives you all the internet use you need when you’re in the UK. With all-you-can-eat data you can use as much data as you want. This means you can use your smartphone as you like - so you can download apps, browse the web, look at maps and check your emails as often as you like without worrying about going over your data allowance.
You get all-you-can-eat data when you buy an All in One 15 or an All in One 25 Add-on. Our All in One Add-ons are a great way to get more minutes and texts than you’d get with a regular top-up.
