Kind of a dumb question iPhone 12 question here. My wife and I are Sprint customers. With Sprint becoming TMobile, we were sent new SIM cards. I swapped mine out easily, no issue took about 30 seconds. Figured I'd change my wife's as well. Couldn't get the new SIM card to fit in the holder. I think it the perforated edge on the card is to blame, but I also don't want to fuck with it too much or jam it in and cause other issues. So instead of messing with it in the middle of the day I decided to put the old one back in and deal with it later. The old one fit right back in, but her phone isn't reading it. She can't make a phone call, everything fails.
Any ideas on how to resolve this? I tried restarting the phone, taking the card out and putting it back in, etc. No dice. She made an appointment to go to a TMobile store this evening to have them straighten it out but if there's anything I can do to avoid that hassle, I'd appreciate any guidance.
