Can’t log into account

[Mitch3]

Used email I receive statements to try and log in, when entering the code from my phone it says another account is registered and won’t let me log in.

Getting a lot of this as O2 try to implement their new billing system

If you are trying to log in to the My O2 app

Instead try the web version 

https://accounts.o2.co.uk/signin

If that works then delete the app, reboot phone and reinstall 

If none of that works then 

You can call O2 on 202

Or use the social media links below

Message them on Social Media. Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG)
