It is not a given that those codes will on every Samsung device. What firmware are you on?

The above list was on a forum I found which states these should work on the S23.

I have the same exact phone and I was on the phone with my carrier for 45 mins. I spoke with 2 reps and would not believe, they had no clue what mmd codes were. And they work for a mobile phone company. And if that wasn't bad enough, I called samsung and he too did not know what a mmd code was. He insisted I meant mck (used to unlock phones from carriers. ) I finally just got fed up and gave up after an 1hour of wasted time. So... samsung.... are you going to respond and fix this?
