I have a cingular bb 8800 and i was able to unlock it. However, when I put a T-mobile sim card in, theres a tmobile logo, but for some reason i can't make calls. I can send and receive text messages though. When i try to place a call i get "Emergency Calls Only." My tmobile sim card is working perfectly fine, i checked, i tried doing a reset on the phone, but still same problem. Can anybody help, PLEASE? thanks
