First hit menu then back. Then I hit menu-select-4 and and then hit menu then back and it gives me a list of options. Never messed around in there but I just looked around to see what was there. I tried 1,2,3 and phone just rebooted but nothing really happened.

Hm...
I do *#9090# and see:
DIAG CONFIG
[1]DM/DUM over HS-USB[]
[2]DM/DUM over HSIC[]
[3]DM/DUN/RmNET over HSUSB[]
[4]DM over UART(*)
[5]DBG MSG ON(*)
[6]DBG MSG OFF(*)
Could someone check what the defaults are?
Ok did the sequence and found it
What is "blocking mode enabled"? Did I push something wrong?

How to SIM unlock Samsung Galaxy S4 SGH-M919 (tested - works)
Hi Everyone,
I'm a long time lurker and benefited greatly from the postings here at xda.
So I'd like to contribute something back.
After trying many methods and reading all the posts in the various S4 forums, I finally found a way for SIM unlock that works for me.
I have tested it, and it works on my T-Mobile S4.

This thread on how to unlock
chavxxx's post pointing to the right final step
Here are the steps:
Goto phone dailer, and enter *#27663368378# for the debug service menu.
In "ServiceMode", select [1] UMTS
In "UMTS MAIN MENU", select [1] DEBUG SCREEN
In "DEBUG SCREEN", select [6] PHONE CONTROL
In "PHONE CONTROL", select [6] NETWORK LOCK
In "NETWORK LOCK", select [3] PERSO SHA256 OFF
It should show:
SHA256_ENABLED_FLAG[1]
SHA256_OFF => SHA256_ON
Now touch the first line SHA256_ENABLED_FLAG[1]
It should show:
MENU NOT EXIST
PRESS BACK KEY
Current Command is 116631
Now press the menu button and select "Back"
It should show:
SHA256_ENABLED_FLAG[0]
SHA256_OFF => Not Change
Again, press the menu button and select "Back", and you're back in the "NETWORK LOCK" screen
Press the menu button and select "Back", and you're in the "PHONE CONTROL" screen
Press the menu button and select "Back", and you're in the "DEBUG SCREEN" screen
Finally, press the menu button and select "Back", and you're back in the "UMTS MAIN MENU" screen
Select [6] COMMON
In "COMMON" screen, select [6] NV REBUILD
Now you are in the "NV REBUILD" screen, you should see the following text:
------------------------------
Golden-Backup exist
You can Restore Cal/NV
------------------------------
Now for the final step.
In "NV REBUILD" screen, select [4] Restore Back-up
The button lights for menu and back should come on, and the phone will auto reboot in a few seconds.
Note: chavxxx's post of selecting "[1] Load default NV" DID NOT work for me.
Congratulations, your phone is now unlocked.
Stick in a sim card from a different carrier and try it out.
Please post followups of your experience with this unlock method.
Thanks, and good luck!

Can't verify with the SIM card yet but the sequenses worked for S4.
What are the additional steps for S3?
I can't test because I got my sim unlock all ready by paying 25 for it when the phone came out
