Mobile top up - online

There are lots of different ways you can top up your mobile phone. Choose the one that suits you best, or chop and change depending on where you are, and what's easiest.

Tip: Before you can top up using your mobile or online, you'll need to register a debit or credit card. It only takes a few minutes and as an added bonus, we'll add £2 credit to your balance the first three times you use your card to top up £10 or more.

It's quick and easy to top up in My T-Mobile from anywhere in the world - all you need is a computer with internet access and your My T-Mobile username and password.

Topping up in My T-Mobile is particularly useful because while you're there you can also:

  • See if your account has been credited
  • Check your itemised use for the past 90 days (if you're the account holder)
  • Send a webtext (charged at your price plan rate)
  • Do lots of other useful stuff

How to top up online

First, you'll need to register your credit or debit card details in My T-Mobile. Topping up is part of the card registration process.

Next time you need credit, simply log in to My T-Mobile and select 'Top up now'.

Make sure you have a registered card handy because you'll need to enter the last four digits and the three-digit security code on the back.

Tip: When you register a card, our system checks whether the address you entered when you signed up to My T-Mobile matches the card billing address. If the addresses don't match, the maximum you'll be able to top up online in a 30-day period is £30.

If you want to top up more, register a card with a billing address that matches the address in our records.
