I've seen users with a similar issue when they insert the SIM card backwards, which will damage the phone. You could repair the phone with PCC

Sir, i had the same problem and i found a solution today itself.
Step1: go to setting > mobile networks> select the preferred network type for that sim which is working. I did to LTE though sim was GSM. And select the preferred network type to GSM for non working sim.
STEP2 : then interchange the preferred network types and you will see that, your sim will work as previous.
