Have you taken the SIM card out and reinserted it? If not,it could fix it. You need a small paper clip to pop the sim tray. Take the card out carefully and put it back in,power the phone off and on.
If this still doesn’t work,you could reset network settings or fully erase and reset the phone to fix software issues…which I doubt would work because it’s probably damaged.
phones have a special chip that’s soldered to the logic board. It processes cellular/phone service. Or even a power chip to provide it power. They usually have balls of solder they flatten when soldered on…they sit on the balls. When you drop it,it can break a solder joint. This requires micro soldering.
It’s not as easy to find people to repair hatch phones. It’s usually iPhones or Samsungs.
Hopefully it’s just a nudged SIM card.
