I just purchased the galaxy s2x from koodo mobile. I want to unlock it to the telus network so I went and bought a telus sim for it. I have not used the phone at all, have not used the koodo sim card at all. I attempted to unlock the phone by putting the telus simcard in there, but it does not ask me for an unlock code. It recognizes that an unregistered sim is put into the phone, but it still won't ask me for an unlock code. Any help? This is really driving me crazy.
