iMessage and Facetime Number Has Expired
I have this notification that asks me to remove and reinsert the sin card to keep using my number that apparently has expired but nothing happens when I do so. Also, I’m not able to register this phone number for iMessage and Facetime, but any other sim card that I insert immediately offers me to activate as iMessage contact number.
Q: How do I re-register my original phone number?
iPhone 8, iOS 14
