iMessage no phone number.
Hello, I have a problem. I have iPhone 11pro (iOS 14.2) When I insert SIM card to it, there is no phone number in Phone settings-> Phone -> my number. Its empty frame. I Can't change it, or add this number. Well, it affects to iMessage, because it is not working with phone number, just with email... I tried to log out from iMessage / FaceTime on Mac and iPhone, then log in, change Apple ID password, but its not working either.
If I insert different SIM card from different mobile operator, it works great.
Problem is with mobile operator - "Lajt mobile" in Poland.
iPhone 11 Pro, iOS 14
