Once the device has been unlocked you can then take it to whichever carrier you want, or even gift the handset to a friend overseas.
If you have a Samsung Galaxy handset you can go ahead and unlock it free of charge by checking out the steps below.
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
This is code that has been used for some time and chances are it could lock many of the Samsung Galaxy handsets, so give it a go. Of course we don’t know how long the code will last, now that it is out there.
