But, they told me that since i cancelled the service in sprint, they can do nothing to unlock my phone, even with a unlock code.
they said that i should unlock my phone before cancelling the service.
So, what can i do now with the unlock code? how to unlock my phone with the code? is there any post here that can solve my problem? many unlocking posts seem too professional for me, and i'm really in a hurry.
i bought a familymobile sim card, and it just show that "invalid sim card", when i insert it in my phone.
