Hi, I cannot use O2 app

Try uninstalling the app, rebooting the phone and reinstall

We’re just customers like you but it sounds like you’ll need someone to access your account which can’t be done from here. If you message O2 using the links below, they should be able to help you with this
or give them a call on 202  or 0344 809 0202

As an alternative, you could try logging into MyO2 using the link at the top of this webpage.
