Number porting

[B-S]

I've recently switched to O2 and set up an account. Today my old mobile number ported but the my O2 app is still logged in on the new mobile number that came with the new SIM. Now I can't access my information correctly. How do I change my mobile number in the my O2 app?

It will probably update itself eventually.

You need to delete and reinstall the app.
