Samsung - How to input the unlock code

Samsung Unlock Code Instructions

Nearly 90% of samsung model can be unlocked in this way

1) turn on the phone with the sim from another network
2) Phone will show which code you need to input (NCK, SCK, SPCK)
3) Input the unlock according to which one the phone requested
4) Phone unlocked

If those above don't work to you. Eg Samsung Z105 Z107, ZX10, ZX20, A707, A437, X497, C417, L700, try these two alternative method

Method A

 
1 - Switch ON your phone with a not Accepted SIM Card,
2 - Compose : #7465625*638*CODE#

PS - Code = unlock code which I suggest u input from NCK first where most provider locks the phone on this level

Method B

Switch ON your phone without a SIM Card,
Type : #0111*CODE#

 PS - Code = unlock code which I suggest u input from NCK first where most provider locks the phone on this level

Sometimes, if you have input the wrong code many times, you could get PHONE FREEZE. Then you will need to input the unfreeze code first and then input the unlock code after that. Then it will show "NETWORK UNLOCKED" message on screen (ie. Phone unlocked)
