So I have an iPhone 11. All of a sudden, just like other users, I randomly have no service bars (literally none) and can’t make or receive calls or messages unless they are iMessages through wifi. I tried resetting my phone, I tried removing the SIM, I tried resetting network stuff, even chatted with Verizon forever. What is the issue. I know it’s not my phone because of so many others with the same problem. Do I need a NEW sim?
