New phone can’t change to old number

[N00la]

I have new phone - all transferred - closed old phone. Kept old number 02 bil shows old no. The new phone won’t display my old number - I’ve tried changing this on settings but it won’t save it.

Hi @N00la 

It will update itself in a few days when the system has caught up. If not then contact O2 on any number in this guide Guide: Coronavirus Community Help and Support
