This service supports many AT&T, Cricket, Xfinity and Spectrum Samsung models such as:
NCK (Network) and MCK (PUK) Unlock codes are provided by this service.
All codes are 100% correct, coming directly from the Samsung database.
For refund requests for non-working codes video proof will be required.
In case of a server delay/maintenance some orders can take up to 5 business days.
NOTE: If you get something like "Network lock unsuccessful" it means that the phone has the unlock counter locked.
SOLUTION: Enter the MCK code to unfreeze your phone first (this will also state it was unsucessful) followed by entering your unlock code NCK and it will unlock your phone or enter MCK code power on/off phone and try again NCK code. UNLOCK DONE.
