Ok i've got a motorola ROKR E1 and its on t-mobile. I bought a new t-mobile simcard and i put it an and it registered fine. However i tried to call 150 to register my top up card and i got this message : Call failed Not allowed?
I then put the sim card into my N-Gage and tried 150 and it worked perfectly. Can anyone offer any advice please? Thanks Frank Archer
