IPhone 5c cannot send SMS urgently.

Card cutting problems may not directly prompt SIM card errors, and a small part of them will have various minor problems. Can you dial out when the text message can't be sent out? Anyway, there is a similar situation in one of the places I have been. The phone can only be dialed a few times, and the short message is simply a failure to send. In this case, a base station of China Unicom has a cramp. If you can't send text messages in several places, it's not the base station. Better try someone else's card. Anyway, if there is a problem, we usually use the elimination method to find the reason. View the original post "";
