iPhone 13 started saying Invalid SIM and I have lost cellular connection and all SIM services
All of a sudden last night my iPhone 13 started saying Invalid SIM and I have lost cellular connection and all SIM services. I’m travelling and on unlimited roaming package and never opened my SIM tray since I bought my iPhone. I tried all the quick fixes mentioned on Apple support but none worked.
