gonna be hard for anyone to say what is wrong because we cant see what you have written or not written but voice service depends on a few things mostly mdn,min,sid,prl and mmc/mcc check those first.

i figured it out.. it was the A key.. i never wrote the A key because i figured it wasnt needed.. but soon as i wrote that the phone was able to make calls and receive texts.. so must be the A key is verified with the network each and every time you make a call or text i assume.
