Repeated SIM card failure, and now iphone XR can't make or receive calls
I have had an iphone XR for about a month. It repeatedly has SIM Card Failures. Each time this happens, I have to shut the phone off and reset it. I have taken the SIM out and cleaned it, nothing seems to work. Today after the SIM failure, I reset the phone, and "Boost" comes up as the provider, but I cannot make or receive calls. Calls I try to make say 'call failure', calls to me ring to voice mail. Please help. Is the SIM faulty?
