Unlock ATT Note 3
Find this one online anyone try that? can someone confirm if it works? ATT note 3 coming tomorrow. but i want to use it on Tmobile.
first take out the SIM from the Galaxy Note 3 and put in its place a SIM from a different carrier, then turn the device off and on.
After you do this, enter into your dial pad *#197328640#. Then, at your main menu of your device: >  UMTS >  Debug Screen >  Phone Control >  Network Lock > Options  Perso SHA256 OFF. Pause about 30 seconds, then go back to your main menu and select back. Once you’ve done this, you ought to see the words “Network Lock.” Select  NW Lock NV Data INITIALLIZ.
If you’ve done everything correctly, you should see the words “Asterisk Pound One Nine Seven Three Two Eight Six Four Zero Pound”. That’s all there is to it!
