Problems topping-up

If you're a Mobile Broadband customer, you'll need to buy an Add-on to use the internet in the UK. If you're roaming abroad, you'll be able to use existing credit to get online.

If you’re having problems with your credit or debit card, there are a few things to check:

• Make sure your card’s registered to the same UK address as your account
• Check if your card has expired
• Double check you’ve entered all your details correctly
• Make sure you have enough funds in your account

Still having issues? Chat with your card issuer, or you can grab a voucher top-up instead. Just so you know, we have a limit on how much you can top-up a day. This is just to protect you from fraud.

There’s a couple of reasons why you might be having problems with a voucher top-up:

• Make sure you’ve entered the voucher number correctly
• Try turning your device off and on again
• Check that the voucher hasn’t already been used. It can’t be activated more than once, nor cancelled once it’s active.

Remember, we can’t give refunds for vouchers.
