Hello!
My restored iphone 7 displays “unavailable sim” problem. Earlier it could be fixed by reloading sim out and in, but now my cellular works for only several seconds and then crushes again. I checked if the sim is ok, and the sim card slot also works without problems. I’ve heard that Apple support can fix it on some soft level. Is that so?
iPhone 7, iOS 13
