IPhone 14 pros have sim card problem. This problem indicates that the phone is not accepting the sim card. I watched videos of it. It's on RU-vid, but it doesn't work. My biggest advice to you is to go to an operator, just like me, and get a new generation SIM card and insert it into your phone. Even if you are using both, I recommend you to get one of these sims as my wife and the other one, it works very well
