My blackberry Z10 003 t-mobile unlocked says phone not allowed mm#6.I can't ring or text,rejected Sim. What does this mean and how can i fix it? Help needed
Has it said this ever since you unlocked it? It sounds like it is not accepting your SIM card. Are you able to try another SIM card in the device?
Generally the mm#6 error appears if your phone is NOT unlocked and you are trying to put in a different carrier's SIM. #mm6 can also appear if your phone is "barred or blacklisted". If you bought the phone from a private party and it was stolen, and the legal owner reported its IMEI, it will be blocked on all networks.
