The codes are dubbed to the Holy Grail as there is no way consumers can get their hands on them. However, thanks to the leaksters, we now have the unlock code for the Samsung Galaxy S3, S4, Note 2 and Note 3.
If you’re a user of any of the carrier-locked device mentioned above, you can now unlock them with the code below. Doing so will take out the pain of switching telcos and even selling the smartphone when you don’t need them. Just perform as per instructed.
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
We do encourage you to unlock your device as soon as possible. After all, there is no telling on when Samsung might roll out an update which will cancel these codes.
