If it is locked due to wrong lock code entry then u required to reset the phone to its original state when u bought. Want to reset the phone ? All ur user data will be erased. Reply if agree. I will let u know the reset process.

You can purchase such code from any vendors online and you can also have a lookup at this free guide

do you want the unlock carrier restriction or unlock screen?
Samsungimeiunlock.com is unlocking your phone in 10 minutes.
If it's a screen lock I am afraid you have to hack it somehow.

You'll need to contact the carrier, manufacturer, or purchase one online to receive the unlock code.

Hi, You may contact your carrier provider Samsung SCH-U650 Unlock Code to unlock your phone. I suggest you can visit Samsung Unlock Code site, they will provide you an accurate code fast with easy to follow instructions on how to unlock your phone.
