Hi need help with log in

[JJ22]

Need help to sign 

[pgn]

Sign in to MyO2, @JJ22?

Guide: How-to guide for My O2 and the web version, if app is broken, is https://accounts.o2.co.uk/signin

The app sometimes needs a complete refresh: uninstall, reboot handset, reinstall app from your phone's app store, @JJ22 - good luck!
