Remove SIMLOCK - Unlock Your Samsung Galaxy SIII for Free (Unlock GT-I9300)

So, you've received your new Samsung Galaxy S3 but it's locked to a particular network - here's how you can remove the Sim Lock so that you can use Sim cards from any network operator.

There are 2 methods I will describe for you here.
First Method is easiest, as it uses an App from the Google Play Store
Second method uses Windows 7, some software and your USB cable to unlock your Galaxy S3

For both methods, your Samsung Galaxy S3 should already be rooted.

These tools are used at your own risk - I will not be held responsible for any damage caused to your device by using these tools. 


Method 1

On your phone, go to the Google Play market and download Voodoo Galaxy S III SIM Unlock.


Follow the simple instructions from within the app and within seconds you will have unlocked your Samsung Galaxy S3 for Free !


Method 2




To start, download Valhalla Unlocker - Galaxy S III from here
Extract the files to a folder on your desktop
Connect your Galaxy S3 to your PC with the USB cable
Run the program: Valhalla Unlocker - Galaxy S III.exe

Refresh to find your phone, then choose your phone from the list.

Click on Unlock My Phone


The above screen should load.
Click step 1 - allow this to complete
Click step 2 - allow this to complete
Click step 3 - allow this to complete
Click step 4 - allow this to complete

Congratulations - Your Samsung Galaxy S3 Is now Unlocked to use on any network with any simcard.


Information from the developer:
It automatically backups your original files to a folder called backups, in the same location as the extracted Valhalla files are placed.
After completing the 4 steps for unlocking, you should have an fully SIM-unlocked Samsung Galaxy S III (GT-I9300 ).

It can take up to 15 seconds after completing the unlock for your phone to connect to your service provider's network.
You may also notice that phone .apk crashes a couple of times during the unlocking process, it is completely normal, just press OK and continue.

Future versions will include the ability to re-lock your phone from backups made by Valhalla or Voodoo Galaxy S III SIM Unlock.


Thanks goes to 'oxtercfrom XDA forums for this tool.

    1. I've heard of others with that problem - I think it means it will not work with the Firmware on your phone - there may be another method which can be used though I can't recommend anything
      try looking on the XDA forums

    1. I couldn't say for sure, I recently installed a custom 4.1 ROM and it did work on that, though I've heard of others having trouble with it

      XDA Forums are your best source of information if it does not work for you

      I can't recall which ROM I ended up using, I had tried 4 or 5 before finding a stable one.
      I always download them from XDA: http://forum.xda-developers.com/forumdisplay.php?f=1563

      It's got loads of ROM's and Tools for the Samsung Galaxy S3

  3. Yeah, I think when that happened it was due to the program not working with the Firmware on the phone.
    I found some apps which may work for you, though maybe not
