Unlock Samsung Galaxy S3 And Samsung Note 2 Phones For Free

If you are a proud owner of a Samsung Galaxy S3 phone or a Samsung Note 2 phone then we have found a way for you to unlock your phone for life without paying a single dime to anyone. Unlocking a phone means you will be able to use it anywhere in the world. You are no longer required to use only your carrier’s simcard. For instance, if you are in USA and you got your Samsung Galaxy phone, then you can only use an AT&T simcard with it. However, we have found a way to remove that limitation. You will be able to use whatever simcard you want to use with your phone. Even within USA you will be able to use T-Mobile or any other carrier’s simcard in your unlocked Samsung Galaxy phone. You will also be able to gift this phone to your friends abroad, they just need to add their own local simcard and this phone will work out of the box.

Disclaimer Before You Unlock Your Samsung Galaxy Note or Galaxy S3

Before we put this guide out, here is the disclaimer:

  1. We have tried this method and it worked fine. We cannot guarantee it will work on all phones out there.
  2. If something goes wrong with your phone or your number, we will not be responsible for it.
  3. Your carrier might void your phone’s warranty if that concerns you.
  4. This method was also posted on xda-developers forum last week, we do not think we stole from him/her or the other way but this is just a miraculous coincidence.
  5. The manufacturer might remove the key combination we are going to use and hence it might not be there with new batch of phones made after December 1st, 2012.

Free Samsung Galaxy Unlocking Guide

Having put the disclaimer out there, we have saved our butt from hated comments. Please know that things can go wrong as Murphy’s law prevails. However, because the same software behaves similarly, if you do not have a conflicting app on your phone you should be fine following the steps to unlock your Samsung Galaxy or Samsung Note phone.

Here are the much awaited steps to Unlocking Samsung Galaxy S3 or Samsung Note 2:

5. All of the phones are carrier unlocked, but if they do not work in your country no cash replacement will be made.
  • Insert your foreign simcard – a simcard that does not belong to your carrier and hence will not work currently.
  • Restart (ok, turn off and on) your phone with the foreign sim in it.
  • Samsung Galaxy  note or whatever you call the Samsung N7100 in your country can be unlocked. So is the case with Samsung N7105 and a bunch of other models that we are still uncovering. Open your dialpad and enter the following digits in order  *#197328640#
  • 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, then go back one step by pressing the Menu button, select back, which should have brought you in [6] Network Lock, then choose [4] NW Lock NV Data INITIALLIZ.
  • Just to make sure you don’t make mistake reading and we did not make mistake typing and the computer did not make mistake displaying here is a worded equivalent of above sequence: Asterisk Pound One Nine Seven Three Two Eight Six Four Zero Pound. Some people call the Asterisk button the star button and the Pound button is also called the hash button simply because of the symbol they bear – no shit Sherlock.

This is it, your phone is now unlocked and can be used with any carrier in the world.

Unlocking other Models of Samsung Phones

It appears that this is the secret code that Samsung has had for a long time. Now that secret is out there might be other models that can be unlocked using this hack. You can try this on other models and if you are successful unlocking other samsung phones, leave a comment and we will update this post with that information.

  1. Hi,

    I tried to unlock mine and my wife’s Galaxy S3 phone. My wife’s phone worked fine following your instructions. Thank you.

    Mine (New S3 747) , however says “USSD code running and then “connection problem or invalid MMI code”. any suggestions?

    • Dear Charles, that happens when your phone is rooted and is not the same as AT&T or the carrier sent you. Have you ever tried rooting (unlocking, changing boot screen etc.) it? If that is the case you wont be able to unlock using this code.

    • You need to re flash the default ROM and unroot your phone. Then it may work. reply with results please.

  2. Sorry if this is a dumb one. What is the purpose of unlocking a phone? Why would I unlock it? Do I get any extra hidden secret power of my phone?

    • Dear Bobby,

      The advantage is that you can now use a simcard that does not belong to your carrier. For instance, we posted about how one can save money moving away from AT&T (Read here http://www.freecallshub.com/2012/10/warning-quit-att-connection-reading/) but if you wanted to stick to AT&T (or any other carrier) because of the phone they gave you, now you can take the same phone and go with a much cheaper option.

      Also, if you go out of country for a vacation, you can just put a simcard of that country which will save you a lot of money on roaming costs of AT&T. Hope that answers your question.

  3. Oh Dude. I passed a deal of $200 for Galaxy note. Only if I had read this earlier. Guess who joined your mailing list today?

  4. Works on a Samsung Relay, but be aware that it requires FACTORY FIRMWARE, not custom built AOSP, which does not provide this function.

  5. Thanks…It work with my T-mobile Note II
