My o2

[Junayd]

It won’t let me log into the app and I’ve had my sim in for two weeks

Sometimes the app can get itself in a twist.

Can you access your MyO2 using your browser:  https://mymobile.o2.co.uk/ ?

If web version works, force-stop the MyO2 app and try again - or uninstall the app and reinstall, then try again.

Good luck.
