I phone 7 no service issues in status bar

Had that happen to mine back in Oct of 2020 and was greatly concerned that an update caused it. I run a small IT business and rely on my phone for communication with clients. I was "dead in the water" and had to quickly switch to an old iPhone I had in a drawer. Communicating with my cellular provider I was quickly referred to Apple support and the expedited the repair via mail-in service. I upgraded during the repair process (1.5 weeks before I received the repaired phone back). I had no idea of the "repair program" that Apple had going.

Just a few days ago the same thing happened to my wife's iPhone 7. I located the webpage that Apple has set up for this "No Service" repair and proceeded to go through the process of setting up a repair for her. Long story short, I was set up with an appointment at our local Best Buy store (45 miles from my residence), drove there later that day and was told that Apple no longer is covering her phone. Wasted trip and angry that they did not tell me the repair service date had run out on this phone, I called Apple and it was confirmed.

I know how you feel. I was never sent an email advising me of this repair program because these phones were purchased used. Luckily, I had the one fixed in October and was able to switch it out for my wife. As for the old phone, a cellphone shop might purchase it for parts.

You failed to get it repaired during the designated time frame.
