Remove and reinsert SIM card to keep using FaceTime
I have switched providers keeping my phone number but keep getting iPhone messages to remove and reinstall my SIM to use iMessages and FaceTime. I have done that and checked phone number in settings but the message has reappeared. I have had a series of SIMS whilst away which may have contributed? I see others have experienced this but I can’t find a solution. Using iPhone 13 and iOS 17.3.1
