Not allowed to use my o2 app

[Lowrilou]

I am unable to long into my o2 app.

I am also having issues with upgrading my phone early because “there are changes” on my account - I have not made any changes…

I have been having issues with my o2 account for the last few years, and it’s to they point now that I am tempted to leave and find a new provider if things can’t be sorted

Try online https://mymobile.o2.co.uk/
If using the app, try deleting, rebooting phone and then reinstall the app.
This is a customer to customer community, not O2.
You need to contact O2.
Message them on Social Media. Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG) or give them a call on 202 or 0344 809 0202 

Try in store.

Or you can call sales on 0800 081 0255
Thanks
