Hey man sorry to bother you, I have just recently learned about these code and I found this guide. I was wanting to give them A try, just from quriosity. But upon me trying even this code I keep getting this message that pops up, saying saying "connection problem or invalid mail code. (For my galaxy s21 ultra 5g.) This also b is not my first obe trying I also had tried another one but it said you may want to try codes for your specific phone. That's what landed me here in the first place. Do you have any idea what I'm doing g wrong? Or is there something something I have to do prior to this?

This is not working my Samsung galaxy S21+ factory unlocked One UI 4 Beta, what could be the reason? or there is alternative code

Secret codes do not work on Verizon so I guess it don't matter if you own the unlocked phone or not either way you don't really own the phone apparently Verizon thinks they do pretty stupid

This never works for me. Always says no connection or invalid MMI code. What gives?

S21 Ultra on Verizon

FYI - from what I can tell, newer Verizon Samsung phones have these pieces of functionality disabled out-of-the-box. However, I was able to successfully activate them on my S21 using instructions here:

I think it is fair to say, though, that neither Verizon nor Samsung either countenance or support doing this, and you probably do so at your own risk, possibly voiding some kind of protection or warranty offered by either in the process.

That said, it is a pretty simple procedure (at least on a Windows computer); just be sure to install the Samsung USB driver for Windows before you start.
