Owners of the Samsung Galaxy Note 2 and Samsung Galaxy S3 who have a device That is locked to a carrier May be happy to knowthat They can unlock the handset for free. When the device is unlocked it can then be used anywhere in the world, Providing of course you are not tied down to a contract.
For instance if you recommended for the AT & T version of the handset in the U.S., you are only able to use the handset With that carrier. If you unlock the device you would be free to move to another carrier. You could even send the device to a friend or relative overseas And they would be able use it with whatever carrier They wanted. So here is how you unlock your handset.
This Applies to the Samsung Galaxy S3 alongwith the Samsung Galaxy Note 2nd
Put a SIM card into the handset That is not from your carrier. Turn the device off and on while the SIM is still in place.
Open up the dialpad and key in * # 197328640 #. Go to Main Menu> [1] UMTS> [1] Debug Screen> [8] Phone Control> [6] Network Lock> Options [3] Perso SHA256 OFF> then wait for 30 seconds or so. Then hit Menus and choose Back. You should now see Network Lock. Then choose [4] NW NW Lock Data INITIALLIZ.
To make sure you did not make a mistake, the sequence you shouldhave typed in is: Asterisk Pound One Nine Seven Three Two Four Six Eight Zero Pound. However some people call the asterisk the star button and the pound button is sometimes called hash.
You should now be the owner of any unlocked version of the Samsung Galaxy S3 or Samsung Galaxy Note 2 and you will be able to use any SIM card in the handset. Samsung has been using this code for sometime so it May work on other types of devices too.
