One response mentioned reinstalling iOS, but I don't see an option for that anywhere. It just takes me I have the most current version.
When I have "full" WiFi and no service, my phone just says No Service and I can't make or receive calls. It used to say iD Wifi (or something similar).
I've already tried restarting the phone. I have an iPhone 7+, on iOS 12.1.2 (the latest version), & iD 35.1
