The MCK doesn't come from AT&T. That comes from the phone manufacturer. That's why it's called "master" code key.

You won't get it asking for it on a public forum that is mostly for other users like you and me.

Oh, and don't bother trying to ask Samsung either. We've been through this a bunch of times around here. Samsung will just automatically assume the device is stolen and will tell you to "call your carrier".  Because they can't be bothered by this kind of thing. It's cruddy customer service, I know. But that's what they do (in fact, they are known for it).

What you can try to do is filling out an FCC complaint. Sometimes that will force AT&T into getting it from Samsung. Harder for Samsung to just blow AT&T off.

Otherwise, you can try one of those online unlocking sites. Some say they can get the master code too. But, it'll cost you. And some of those sites aren't legit, so you kind of need to check them out a bit. Look for other online reviews - not reviews on their own site.

If you don't want to do that, either keep the phone on AT&T, or toss it.

If you bought this phone from a third party seller and you aren't in the US to use AT&T, try returning it and get your money back. Because it'll be even harder if you were never an AT&T customer to begin with.
