I need a new SIM in my iPhone 13 as it says NO SERVICE. How do I save anything on my SIM and transfer it to a new SIM?
iPhone 13 - I have a No Service notice so no WiFi connection. I have tried the SIM card from my wife's iPhone 11. It connects perfectly in my phone. I tried my SIM card in my wife's phone - NO SERVICE. So the SIM card is at fault. I have a couple of new, unused SIMs from previous iPhones (where I have just swapped the SIM from an old phone into a new phone). So, what info is on my existing SIM card and what do I need to do before replacing the SIM with a new SIM card? Thank you.
