Galaxy S2 SIM Unlock code finder will find the SIM unlock code for your device, or the unfreeze code. It'll take a few minutes to run, but you should end up with the code to SIM unlock your device. If the code doesn't work, don't keep trying it !. You may end up with a freeze. In that case, the program can also find the unfreeze code, but if the SIM unlock code is wrong in the first place, maybe so is the unfreeze code :)

Based on Odia's work here: http://forum.xda-developers.com/showthread.php?t=1064978

Thanks / Donate

Press the thanks button, and/or donate (or not) to Odia and/or myself

Also, please rate it 5 stars in Market if it works for you... I think some people who sell unlockers are purposely 1 starring it (seeing as nobody has reported any problems)

Also, attached !

!!! IMPORTANT NOTE: On some newer SGS2 devices, it does not work at all. You can try "Galaxy_S Unlock" app from "Helroz", but beware, it's unlock method is much more dangerous !!!

THIS IS ONLY FOR NON-US RESIDENTS, SORRY. YOUR LAWS HAVE GONE BACKWARDS, YOU'RE NOT ALLOWED TO SIM UNLOCK NO MORE

Downloaded and ran on my unlocked device and it came up with 00000000.

I am running to find the unfreexe code too, though not really sure how it works? Should I expect a valid code?

There is no SIM unlock code because there is no SIM lock ? Not sure about the unfreeze code, but I doubt it'll come up with one.

Thanks.

I thought a SIM unlock code was realted to the device, not to the device and the *current state of the SIM lock* (ie, it must be locked to display an unlock code!)

It came up with an 8 digit number starting 9242

Is it actually a useful number if you have no sim lock?

This is crazy.

Requested my unlock code from o2 over a week ago. They contacted me on Saturday to say they do not have it and that they will have to resubmit the unlock code request to Samsung.

I still do not have an unlock code after 2 weeks of owning the phone.

Literally 5 minutes after seeing the xda tweet about this thread my phone is now unlocked.

Crazy, absolutely crazy that the community can do in 5 minutes what the corporate world can't achieve in 2 weeks.

I am blown away, many many thanks to the op, this is outstanding

I need help - got my S2 from O2 which it's locked to. After nine days, still no unlock code from O2, apparently delays in obtaining them.

Downloaded and ran this app, but failed with 'Could not acquire Supersuer access! Is your device rooted?'

What does this mean and what do I need to do to resolve it?

Thanks in advance.

The message "Could not acquire Supersuer access! Is your device rooted" actually told you what is wrong. Guess you did not root your S2. Follow the link to get your S2 rooted.

I have installed this and got my Unfreeze Code, however the Unlock code is just comes up as 0000000000.

It also take much less than a second to generate it, so I assume there's a problem?

The Unfreeze code took a few minutes and produced an actual code ... have I missed something?

    Hi Chainfire, just poped into your thread to say, APP appears to be working fine.

    As a note for everyone, even on a factory unlocked model the unfreeze code should still be present.
