I recently got a new phone on contract and I'm new with O2.
How would I go about changing the date of which I pay for my phones contract?
Or when would I be able to change my payment date?
I got the phone from an O2 Store on the 25th Of July, I get paid on the 26th of each month and want to change my payment date to the 26th to guarantee I have the money in my account.
