Have you purchased the Samsung S400 phone which is locked to a particular network and country? We can provide the correct unlock for your Samsung S400. Once the phone will be network-free you can use the default as well as other carrier SIM cards. Unlocking a device by code is the easiest method. We provide all sets of codes including NCK, SPCK, Unfreeze/MCK (if in the server only one set code will be available then you will receive only NCK code).

Depending upon the service you choose, you may get the following types of codes for Samsung S400 :
NCK – Network unlocking code is used to remove the simlock.
Unfreeze/MCK – Used to reset the unlock code counter. If you have already tried with too many wrong codes, then it will help you to reset the simlock counter. Once restriction removed, you can again unlock it.
