Having read a few messages on the forum already this appears a common theme.
I ported over my number to a new mobile telephone with ID.
It worked for first few days but now cannot send text messages or phone anyone in my contacts.
I have an Iphone 14.
I checked my phone in settings and it is showing the temporary number for this phone and not my mobile telephone number.
I have tried to change it but it is not saving and reverting back to temporary number.
Please help.
