You probalby need the unlock code call motorolla they should give it to you no problem

Well if its a tmobile phone you need to contact tmobile , if its att im not sure

With that I'm not exactly positive but when I called motorolla one of the options was to ask if you needed a unlock code it may or my not be the same thing but it's worth a shot

You have to have AT&T unlock the handset so that you can use the T-Mobile sim card

T-Mobile although can unlock the handsets (with requirements like having 90 days of active svc) cannot unlock handsets purchased outside of the US and handsets through AT&T
