Unlock galaxy note 2 (easy steps)

All you have to do is enter a code from your devices’ menu; there’s no need to send information to a website, pay anything or wait for an unlock code.
Note that this method may not work for all Galaxy S III or Note II variants. Also keep in mind that this could void your warranty, so proceed at your own risk. Here are the steps you need to take:
1) Insert the desired SIM card you want to use unlocked into your device, and restart the phone.
2) Enter the code *#197328640# into the keypad and press send.
3) Go to Main Menu -> [1] UMTS -> [1] Debug Screen -> [8] Phone Control -> [6] Network Lock -> Options [3] Perso SHA256 OFF (after choosing this option, wait for at least 30 seconds)
4) Go back one step by pressing the Menu button, select back, which should bring you to [6] Network Lock, then choose [4] NW Lock NV Data INITIALLIZ.
If you followed the above steps correctly, your device should now work with the new SIM card!

i've just tried this procedure and i was able to follow and complete all the steps just waiting to try with a different sim card. phone supplied by tmobile, have not faced issues as others have in other posts where some of the menu functions were not visible. will update when have tested with different sim card.

i dont get that last step [6] Network Lock, then choose [4] NW Lock NV Data INITIALLIZ.
the NW Lock NV Data INITIALLIZ doesn't show up what could it be ? is it because i did the update to 4.1.2 ? Help Plz

[Q] Unlock AT&T Galaxy S3

I tried to use the following route several times to unlock my GS3 with no luck. It is still saying no SIM Card. Any other ideas on what I can do?
Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > (after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in [6] Network Lock then choose [4] NW Lock NV Data INITIALLIZ
Thanks..

You need an unlock code if you are trying to unlock it for another network, don't know what the steps in that method you showed is about but I believe you need an unlock code to unlock it as there is no software that can unlock it yet.
Here is a topic about the available unlocks.

It might not work with AT&T S3 as it says : " Please note that due to different hardware, US Qualcomm based GS3 (SGH-T999, SCH-I535, SCH-R530, SPH-L710, SGH-I747...) are currently not supported. Don't leave bad feedback, I can't do much without one of these phones in my hands ! * "

[Q] Help! Unlock Bell Mobility Note 2 - Canada version

Hi everyone,
I need assistance with unlocking my Bell Mobility Note 2 on Android 4.1.2. I searched all over for a solution and have been seeing many duplication of the same solution which didn't work for me. That being said, I tried this:
"Dial the following keys *#197328640#
Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > (after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in [6] Network Lock then choose [4] NW Lock NV Data INITIALLIZ ..... wait for a minute then reboot your phone"
This option [4] NW Lock NV Data INITIALLIZ - never came up on my phone, and only Options [3]Perso SHA256 OFF after waiting for 30 seconds.
Any other alternatives? Any assistance is appreciated!!!

This is the only free solution i think which is the same as you posted

Also if I unlock it, will it void my warranty with Samsung.

After rooting the phone is it true you can unroot the phone to the original state.
thanks

There's a hidden dialer unlock method to unlock which does in fact work for t999 and many other variants .
Follow steps closely
1. Enter the following into the dialler: *#197328640#
2. From the menu that appears choose*
Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > (after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in [6] Network Lock then choose [4] NW Lock NV Data INITIALLIZ ..... wait for a minute then reboot your phone... enjoy!!! There is no confirmation on the phone that the unlock was successfull.... just reboot your phone

Unlocking will not void your warranty, by rooting may.
