Now mobile unlocking with unlock code. Below are the
types of unlocking codes for various Samsungs gsm cell locking and unlocking.
1) Network
unlock codes /nck which is most widely used. These codes are Samsung
imei unlocking codes as they are generated from imei no.
Keep in mind for samsung galaxy dual sim phone. There might be two different imei no for two sim slots. You can check this by go to phone
setting – about phone –status - imei related information –
imei no (slot 1)=15 digit no, imei no (slot 2)=15 digit. In two imei no
last 5 digit of imei are changed first 10 digits are normally the same.
so
it may possible that there are two mobile imei unlocking/ unblocking codes for
two different sim slot. So be carefully which generated unlock code. Provide
proper imei no of the slot for which you are trying to unlock.
2) Service
provider unlocks pin/code or spck.
3) Deep
freeze unlock code / mck which is used for hard locked Samsung Smartphone.

applied.

unlock codes you need following information
Imei no of your
Samsung smartphone,
Serial no of
