Help MCK - Unlock code???

Newbie
After a long long story, I got the unlock codes for my Galaxy.

They sent me the NCK code (that the system prompts with a SIM from another carrier).
I have inserted the NCK code and my phone looks unlocked.
But sometimes it continuously show the roaming icon in the status bar.

They also sent me a MCK code.
Where and for what is this code? Does anyone know?
Is the MCK not informed that's causing the "roaming"?

Thanks! :confused:
 
I had, but most of the results (if not all of them) are just ads of unlock services.
Or its just my bad english... :^(

One of these ads had a procedure of unlocking and it was exactly what I did with my Galaxy.
And it does not use the MCK code...

I just know that the MCK is an unlock code...

NCK = Network Control Key
MCK = ?????
 
How about that (although it's for different Samsung model)

Unlock code is composed like this: #0149*MCK# or #0111*NCK#

1. Press the # button on the keypad 1 time to display #
2. Type the 4 digit code which corresponds to your lock type (in most cases the MCK code will work with code:1)
3. Press the star (*) button on the keypad 1 time
4. Type your unlock code which corresponds to your lock type
5. Press the # button on the keypad 1 time
6. phone should now be unlocked
7, If phone is still locked, you have a 2nd lock activated so please check locks and enter 2nd code

You should consider contacting Samsung Customer Support.
 
I got it from a Samsung employee.

MCK is the code you should input when you locked your phone trying too many times typing the wrong NCK.

So it's kind of the unlock for the locked unlock screen... (!!?!?!?!?!) :^O
 
Hello, NCK is Network Code Key, MCK is Master Code Key. The MCK allows you to unlock the phone when it goes on the block for any type of incorrect code that is inserted

Hi Andremuller, sorry to bother you, I know your post is an old one, but, where did you buy your cellphone, and who provided you with the NCK and MCK codes?

(thanks in advance)
 
i tried calling AT&T but they gave me the NCK only. Then I purchased the MCK code for my Galaxy S10 from UnlockBoot they delivered it to my email in few hours. It worked fine. Hope this will help!
 
I contacted AT&T but they said can't provide MCK. After that I tried UnlockBoot and yes it worked they send me the MCK and NCK in few hours now my phone is unlocked. I'm glad to share that with you guys.
