Anyone who owns a Samsung handset, such as the Samsung Galaxy Note 3, and the device is locked, will be pleased to hear about an unlock code that is used by engineers at Samsung to unlock devices. When the handset has been unlocked the device can then be used anywhere in the world with any SIM card.
Anyone wanting to unlock their handset should remove the SIM card and insert one from another carrier. The device should then be turned off and back on again.
Open up the dial pad on the device and input *#197328640#. Go to your main menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3] Perso SHA256 OFF. Wait for 30 seconds or a minute before going back to your main menu and choosing “back”. You will now see a “Network Lock” message. Choose [4] NW Lock NV Data INITIALLIZ.
If you typed in the sequence right, it should read: “Asterisk Pound One Nine Seven Three Two Eight Six Four Zero Pound”. Remember that some people call the asterisk “star”, and the pound button “hash”.
By now the Samsung Galaxy Note 3 should be unlocked and the handset can be used with any carrier. The Samsung engineers have used this code for some time and there is no reason why it shouldn’t work with other handsets belonging to Samsung.
