My MTN sim keeps showing invalid IMEI. I got a used android phone(Tecno L7), I did a factory reset and when I was done, I kept getting invalid IMEI message, I did what I did and I was able to validate the IMEI numbers on both sims (GLO & MTN), now the problem I am having is that I reset the phone again, did the IMEI thingy and now my MTN sim shows invalid IMEI when put in the sim slot, I tried other networks and it came up immediately so the problem is with my MTN sim. I have tried other MTN sims and the invalid IMEI persists, has the phone blocked MTN sims?
Pls what can I do to validate its IMEI or how can I make MTN sims work on the android phone?
