Thats not good and I can understand that this can be very frustrating. Have you tried the steps listed in this link If you see No Service or Searching on your iPhone or iPad - Apple Support ? If that does NOT help then your iPhone 7 may be part of the iPhone 7 Repair program and you can check whether you qualify by using the information in this link iPhone 7 Repair Program for "No Service" Issues - Apple Support .

You an also, as always, take your iPhone 7 to an Apple Store and have it examined. Good Luck.

According to the screenshot provided, upper left telling you're using "hotspot." You ever try with real WiFi? Like previous post wrote, take your iPhone 7 to Apple Store, or Authorized Apple Service Provider to have it checked out. They probraly can find out what's really going on.

Clarification, I'm not Apple employee, only user of Apple products like everybody else. So you're own your own.
