iPhone - cannot edit / save new number in 'My Number'
Last week I moved mobile network provider and transferred my old number via a PAC code etc.
The phone works when calls made to the transferred number.
The iPhone recognises the new network number and has put it in 'My Number' but, when I edit this number to the old transferred number, I can edit the number but it will not save the edit. So I am stuck with the new network number, which impacts iMessage.
I have iMessage turned off and FaceTime turned off. iMessage says my transferred number is not registered.
Any help would be appreciated.
PS - my wife changed to the same mobile network at the same time, same iPhone model(7) and I edited her 'My Number' and iMessage, with no issues.
