Cannot access my 02 on app

[NJM]

Am unable to access my account

Try deleting the app, rebooting the phone and then reinstall the app

Otherwise :

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

@NJM 

Have you tried logging into MyO2 via the web ? 

There's a link at the top of this page.
