Did you know there are like, tons of things you could do with your phone if you have it unlocked? If you’ve always wanted to switch to another carrier because your current one is not as promising as you thought it would be, or that you’re travelling abroad and want to be able to use their foreign SIM cards, you could do so, only if you have your phone unlocked.
Good news to the people who own the Samsung Galaxy Note 3, Note 2, S4 and S3, because apparently, there has been a leaked code that’s been making rounds in the Internet. Here’s what you can do if you’d like to unlock your phone to be as free as a bird (not literally), since it’s a code that engineers have been using on handsets belonging to Samsung:
1. Insert a new SIM card into your Galaxy Note 3, Note 2, S4 or S3.
2. Turn off your device then turn it back on again.
3. Head over to the keypad and enter the following: *#197328640#.
4. Choose  UMTS >  Debug Screen >  Phone Control >  Network Lock > Options  Perso SHA256 OFF.
5. Wait for around 30 seconds before heading back to the main menu by tapping on “back”.
6. You’ll be able to see “Network Lock” in your main menu. Next, choose  NW Lock NV Data INITIALLIZ.
7. And you’re now all ready to use your Samsung device being officially unlocked.
Yes, you’re very welcome.
