If your model number is one of those listed (you can find your model number on the back of your iPhone 7)
If your model number is one of the ones discussed on the web page above make sure you have a recent back up via iTunes, or iCloud, and call Apple support (1800-apl-care) to schedule an appointment for a Apple retail store or Apple authorized retailer.
Goodluck,
Alexis
try plugging your device into your iTunes computer using a USB cord and checking for an update.
Why is my phone saying no service but is paid for ?
