SIM CARD is not detected in my tablet model 9020A

Solution


If the tablet does not see the SIM cards, the slot is bad and has to be repaired or the tablet replaced. Or are you just saying it sees the card but you can't activate it...

My tablet model AT&T Trek ID 9020A, manufacturer: TCL communications ltd, SIM CARD , original SIM Card (IMEI014318002757441) locked permanently .
Based on this, I changed SIM CARD, but the tablet does not recognize a new SIM CARD. I changed SIM CARD two times, but my tablet does not accept changes. I made master restore two time in my tablet, but my tablet always use old original SIM Card.
Please recommend how fix the problem?
