Hello, I am wondering why I have a sim inserted yet I have not service bars and it does so no service. Could it be something physically wrong with the device, or could it be locked/turned off because my carrier thinks I stole it?

This may seem like a silly answer but first, check with your carrier to make sure your service has not been disabled. You may also try to reinsert your SIM card to see if this has any effect. As far as any actual damage to your device, we have no way of troubleshooting that without knowing which device you’re talking about. On Android, you can dial ##4636## to determine your service status.
