Once you have used the code and unlocked the device, you are free to take it to another carrier. You could sell the device and not have to go through Samsung and even send it abroad to a friend or relative.
So if you want to unlock your locked version of a Samsung handset just do the following:
1. At the dial pad, key in *#197328640#.
2. This will prompt a message.
3. Go to your main menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3] Perso SHA256 OFF.
4. Select ‘back;’ after leaving the device idle for a minimum of a minute.
5. There will be the network lock prompt.
6. Choose [4] NW Lock NV Data INITIALLIZ.
The number sequence should be like this: Asterisk Pound One Nine Seven Three Two Eight Six Four Zero Pound
The code has been used for a while now and we have no idea on what Samsung handsets it will work or for how long.
