OK, you ned to get the unlock code from ATT, once you have your phone unlocked, you need to update the OS with the Tmo version. Just check the tmo website for the software upgrade section. DL the OS you need, and it is straightforward as any other OS. Or should be. Once you get that far you *should* have voice and text. I'm not positive as I was using "incompatible" hardware when I did mine. Let me know if you need any more help.
