Metropcs P769 not working with Tmobile Sim card?
I might have somewhat of a convoluted situation/problem:
I have a MetroPCS LG Optimus L9 P769 which I flashed with Tmobile V20H_00.kdz to get root, and I did. Now I have a Tmobile nano-sim card which I bought new a few days ago, and switched SIM to, and tested working on another two phones. I put it in a microsim adapter to use with my Optimus L9, but when I start the phone with the SIM in, it says "searching for network" but never finds one. If i remove the sim card, the phone says no SIM card but lets me make emergency calls. I kind of expected this whole thing to work, but it didn't...
What could be wrong here?
1. MetroPCS phone not accepting a Tmobile SIM? (will I need to unlock?)
2. Nano SIM via Adapter not working? (but phone recognizes a SIM card and says "searching for network")
