This service supports many AT&T, Cricket, Xfinity and Spectrum Samsung models such as:
- Galaxy S20/S20+S20 ULTRA
- Galaxy Z FLIP
NCK (Network) and MCK (PUK) Unlock codes are provided by this service.
All codes are 100% correct, coming directly from the Samsung database. Verification not accepted.
NOTE: If you get something like "Network lock unsuccessful" it means that the phone has the unlock counter locked.
SOLUTION:Â Enter the MCK code to unfreeze your phone first (this will also state it was unsuccessful) 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.
