I have a Nokia 3650 and I have tried to unlock my phone. It's through T-Mobile service here in the U.S. I took out the sim card and entered the codes from the code generator on this website. I also took a Cingular sim card (to make sure it wasn't already unlocked) and put it in my phone and it told me wrong sim. When I enter the codes it either says: not allowed or wrong code. Please help. Kinda new to this and trying to learn, thanks!
