MCK code

[Tommy0007]

Hello, I've recently bought a secondhand Samsung Galaxy Note 20 Ultra 5G on eBay. Unfortunatelly, the phone is locked to AT&T network. I contacted AT&T and I was told the NCK (Network Unlock Code) which is a 16digit number. Well, because I am a clamsy guy I managed to enter the code several times wrong due to number misclicks and now the phone asks me for MCK (Master Unlock Code) - the code asked when multiple incorrect network unlock codes are entered. Great. I contacted AT&T again and I was told that they do not have MCK code on record and that this code can be obtained only from Samsung. So, I am here.

May I get some advice what are the requirements for obtaining MCK code, which form should I fill in order to request it or who to contact in order to get it? As far as I searched Samsung website and various other resources so far I did not find any suitable information on this matter.

Thanks in advance.

Ask the support directly. It is possible that no one from this community represents Samsung for such an official gadget unlocking.

Thank you for the comments, everyone.

I figured it out after all. The solution for getting an MCK code is to fill the complaint with FCC and BBB against the carrier. This is the only way how to get in touch with people from higher executive offices who will get in touch with Samsung directly and request the code which is then emailed back. So it is solved. Too bad one needs to go through such a hassle in order to unlock a phone which he legitimately owns and that it's not possible to fill out a simple form to receive all the codes at once if conditions are met.
