Old Phone Number in Settings\Phone\Mynumber
IPhone 13 and 14 (both have same issue); IOS 17.0.3.
Changed service providers and were given temporary number on new SIM. After porting old number, the temporary number remains in Settings\Phone\Mynumber. I can edit the number, but it won’t save.
Also, I have a warning message in Settings\Messages\Send and receive that my ported number is registered to my Apple ID but “not associated with this phone” and will expire in 30 days.
How do I get my phone to recognize the correct (ported) phone number?
