My iPhone 7 is showing no service in upper left hand corner. Just updated the phone to 12.1.4
mavJR,
Being able to count on your phone is crucial. We never want to see you unable to get a signal or use your device. We're glad to help. When did this issue begin? What are the city and nearest cross streets to where you are having this trouble? Is there any sort of physical or water damage to the device?
