Pay & Go mobile top up
You know how it is. You're just about to run out of credit and you really need to send a text saying you're going to be late. Or perhaps you need to make an urgent call about tonight's party. That's why, if you've got less than 50p on your phone, we'll lend you a quid until you next top up.
All you have to do is call the O2 Top-Up line on 4444 free of charge from your mobile and select the 'Lend Us a Quid' option. The service is free as long as you top up £10 in the next seven days and the £1 is repaid from that top-up, after which a charge of 25p is applied. You can find out more about it in our Terms and Conditions
You can now top up your mobile automatically – either when your balance gets low or on a certain day every month. You decide when, and how much. We'll do the rest.
