Check your device's user guide for the correct way to insert/remove your SIM.

Have you inserted the SIM correctly? Turn off your device. Take your SIM out, give the gold contacts a rub and put it back into this device. Do you have a case or cover on your device? If so, remove this and try again.

If you are still having issues, turn Flight mode on briefly by doing the following:

Settings > Connections > Flight mode > Tap the toggle to enable/disable this. Please note: if you are currently on a call, putting the device in flight mode will end the call. After a few seconds, turn flight mode off again.

I've tried all of that I've checked everything it is still not working even the person trying to repair couldn't figure it out

@melyxx Who inspected your phone? Was this done via Samsung directly?

[melyxx]

Yes and it still wasn't fixed

Did you get this fixed as I am having the same issue. I also sent it to Samsung and they said they found no issue.
