iPhone no service.
Hello? My phone has been disconnected from service, for 2-3 days now. I have iPhone 7. Whenever I open up my phone, it keeps saying "no service"; "disconnected" etc. I have already backed up my phone and even changed my sim card for a new one. I tried several things like turning off my phone, and restarting network service, etc. If possible, is there any way of checking my phone. How should I fix my phone?
iPhone 7, iOS 14
