Reasons Why Your iPhone Says ‘No Service’
There’s no single reason why an iPhone may report it has no service, so you need to troubleshoot the problem, trying the easiest and most likely solutions first.
Service interruptions may be caused by a simple setting change, such as Airplane Mode or carrier settings. In a few cases, the iPhone needs to have its cellular settings updated through a software update from your cellular service provider. Less often, you need to reset or replace the phone’s SIM card. It’s also possible that there’s a problem with your cellular service plan.
