You can do it via either My o2 on the website or via the o2 app.
Guide: My O2 - Bills section
If you have any issues then you need to contact o2 on 0344 809 0202 or 202 (from your o2 phone).
This is not customer services and we dont have access to your account
I do not work for o2 or any VMo2 /Telefonica/Liberty Global Company
