Top up

[Shelby67xx]

I got £15 big bundle first time.. 

And I received my 16 digit top up code. So I entered the code.. and it gave me £15 credit...  Not bundle!!

Possibly your £15 credit will disappear and your BB will have started now, as O2's systems update overnight, and behave somewhat irrationally in the wee small hours, @Shelby67xx

Guide How to Top Up (PAYG) has all the ways to top-up next month, if needed.

Otherwise contact O2 on 4445 or via Social Media using either of the links just below. Good luck!

Take a look in MyO2 @Shelby67xx at the expiry date and time of your current Big Bundle.

Your new Bundle won't start until immediately after your current Bundle expires. If you have run out of data and want your new Bundle to start sooner, that needs a call to 4445. 👍
