No Sim Card Error on S9+ TMO running Android 10

[eklisiewicz]

Overnight, I started getting a No sim card error. I did a bunch of online searching on this, but the only thing that "fixes" the problem is restarting the phone. I doubt the SIM card has gone bad, but i suppose it is possible. i did not load any new applications on the phone overnight. In fact, nothing in my environment has changed! Has anyone experienced this? I know the advice is to remove the SIM card and reinsert it, possibly that some dust may have gotten in. But I did not remove my case, which is tight to the phone case. Any help is appreciated since I now have to reboot multiple times per day. Thanks.

Can open up the Sim card tray inspect your sim is sitting flush in it , can also monitor in safe mode for a while see if it happens there .
