Answer 2

First, you would need to contact the person/company where you got the code from, and if they can, they should recalculate the unlock code that was processed. You also have to make sure that the information,like the IMEI # of the phone and the carrier that the phone is locked to is correct as the code is calculated off of those information. On the other hand, there is a small percentage of phones that can't be unlocked using the unlock code, but that can't be determined right off the bat.
