How to work: 

  • *The unlock code is "NCK" or "Network" code. Except in the special case when you get "Phone Freeze" message you will need "Defreeze" or "MCK" code.
  • *This way you can check which code you need:

Model : Samsung from 2011 and newer:

  • 1. Insert a non accepted SIM card,
  • 2. Phone will ask to insert code if it doesn't ask for code it means your phone is unlocked.

Model : Samsung from 2010 and older (Galaxy S and older)

  • 1. Go to your phone dial type: *#7465625#  (*#SIMLOCK#)
  • 2. A new menu will be displayed:
  •   [ ] Network lock
  •   [ ] Subset lock
  •   [ ] SP lock

3. ON=locked , OFF=Unlocked

  • 4. If you have displayed [ON] Network Lock - you need to use NCK/NETWORK Code with the instructions below.
  • 5. If you have displayed [ON] Subset Lock - you need to use SCK code if provided
  • 6. If you have displayed [ON] SP Lock - you need to use SPCK/PROVIDER Code.
  • 7. If everything is [OFF} it means your phone is unlocked.
