Hi. I can't receive or make calls. Phone is saying MM SIM 1 NOT ALLOWED but SIM 2 slot is working. I've tried everything. S21 ULTRA.

Your phone has been blocked, it will take CellC on sim 1 and Sim 2 will take all sim cards

Check it could be carrier locked, try stopping the simcards, using the carrier from which you brought phone from on sim 1

Still experiencing this issue on a S21+; I contacted Samsung but none of their suggestions worked. I noticed that sometimes MTN is working on SIM 1 slot for minutes or hours, then it stops working
