We sell unlock codes for the Samsung Galaxy S2 that is currently locked to any European, US or Brazilian network, as well as a number of other worldwide networks. Enter the code to unlock the phone so that you can insert any active SIM card and use the Samsung S2 on that network.
Note: If you have ever entered any incorrect unlock codes in the past, you will need to use the MCK (defreeze code) we sent you for your Galaxy S2. If the above method doesn't work, then go through the steps again, but the first time an unlock code is requested enter the MCK (defreeze code). Then when a second unlock code is requested, at that point enter the NCK (network code).
With all Samsung orders we deliver 4 different codes. The majority of orders will only require the Defreeze code and the Network code. The others are only required where the network that the phone is being unlocked from works differently that the main ones. In the same email that includes your unlock code, you will also receive complete instructions on how to enter it.
