Top up

[Speckz]

I have applied £15 to my O2 balance but for some reason don’t give me the option to pay for my top up with it and asks me for bank details how can I pay with the £15 I topped my account up with ?

Did you sign up for a Rolling Plan, @Speckz? That PAYG option needs to take payment from a registered card only, you'd be better switching to a Big Bundle to use your credit then re-register a payment card later that month to move back to the Rolling Plan: Pay As You Go: Introducing "Rolling Plans" 

Changing tariffs

You can switch between Rolling plans and Big Bundle tariffs once a month by visiting My O2.

If you decide to switch from a Rolling plan to one of our Big Bundle tariffs, we’ll cancel your next Rolling plan payment. You’ll be able to carry on using the Rolling plan allowances you have until that was due. Then, when the plan you have expires, we’ll switch you to the Big Bundle you chose.   When that happens, you’ll need to have enough top-up credit on your phone to buy your bundle. Until you do, any calls, texts or data you use will be charged at the standard rates. 

You can choose to switch to a different Rolling plan any time. When you do, we’ll take the payment for your new plan amount straight away – and when your current plan ends, we’ll start you on the new one automatically. After that, your Rolling plan payment will renew as normal each month. 

Good luck!
