A few more tips on this issue:

 
If the correct unlock code, some models of Samsung displays a message that the code is invalid. In this case, enter the unlock code (NCK or Network) and click Done/OK/OK. After that, enter the code again and Freeze unlock code. Pre BACKUP and do HARD RESET (Settings> Privacy> Factory data reset> Reset phone> Erase all). Specify whether the phone sews and/or modify any ROM (in these cases, even the correct code will not work).
 
Some models may have a specific (other) sequence.
 
The most common problem encountered with Samsung S4 Europe based on Jelly Bean. To solve them, remove the firmware, install the original and try again to make DEFREZE. Record version 4.2.1, although 4.2.2 should not cause any problems.

Samsung - the general information about the unlock from the operator

Samsung mobile phones can be unlocked from any operator of cellular connection of any country.

For USA Samsung phones, please order NCK code using this service: Samsung USA

Ordering the code by the common database Samsung USA, you get 2 codes: Unfreeze code//Network code - NCK

To get the unlock code, you have to specify the model of the phone, IMEI.

Buy the unlock code Samsung Europe (any GSM European operator)

Buy the unlock code Samsung USA (USA operators: AT&T, T-mobile, etc...)

Unfreeze codes are provided in addition to NCK codes as possible, but they are optional, not required ones!

We advice you to think before entering into the phone so that you don't need additional Unfreeze code.

We provide 4 codes by the common database of Samsung!

They look something like this:

NCK: 84174637 Unfreeze: 35390660 SCK: 54279635 SPCK: 49581464

More than 90% of locked Samsung phones under the operator have only NCK lock, but there are some that require SCK/SPCK code as well. It is not possible to order the Unfreeze code separately from NCK code!

Enter all the fields carefully!

If you make a mistake filling the form, you will get the wrong code, the return of credits is not discussed in this case!
