This will not work for Stock Android 4.3 or Higher and downgrading may cause a brick DONT DO IT.

Unlocking cellphones was recently made illegal because a certain mandate expired. Please take a few minutes to sign this petition so we can ensure consumer rights and our ability to use our phones on different carriers:
Petition to Make Unlocking Cell Phones Legal.
https://petitions.whitehouse.gov/...l/1g9KhZG7
THIS PETITION IS CLOSED AND WAS SUCCESSFUL

The current way to root and unlock your ATT Galaxy S3 phone (along with others) can be found here:
http://forum.xda-developers.com/s...?t=2092244
Works awesomely, so good in fact, I donated to the dev. DYLAN

AT&T Users you can now update to Jelly Bean!!!

FOR THOSE THAT DON'T HAVE THE LAST OPTION MAKE SURE YOU HAVE THE LATEST UPDATE FOR YOUR PHONE.

And if ATT give you unlock code and if it doesnt work, then you need to go back to 4.1.1 using Odin and then use the above options to unlock and then go back to 4.1.2.





FROM THE OP:

Those who are having trouble.

1) PLUG IN THE FOREIGN SIM CSED FIRST

2) BOOT up the phone with the different sim card, then it will ask for unlock code. CLICK DISMISS

3) Then perform the 6 step process in post #1

4) be sure to WAIT EXACTLY where it says wait 30 sec, and wait 1min then reboot

---I have better success with the foreign sim in FIRST and unlocking with the foreign sim inside the phone.


Frequently Asked Questions:
  • What is unlocking/what is its benefit?
Only thing unlocking your phone will do is allow you to pop in a different sim card and use that provider's service with your phone -Blacksoxing
  • Will unlocking my phone void my warranty?
It typically won't void your warranty (since some providers WILL unlock your phone for you if you're traveling internationally....)....and it won't help you get updates faster. -Blacksoxing
  • After unlocking the phone, data isn't working on the foreign network (e.g. if you have a T-Mobile phone, data is not working when you put in your AT&T SIM card), what do I need to do?
To get data to work on your FOREIGN SIM, you must change the APN setting. Google for your carrier's APN setting and change that. This is nothing related to unlocking the phone, rather its because you are literally on a different cell carrier and you need to modify the phone to access the correct data network. -OP - lillazyfats81
  • Will unlocking my phone affect my internet speeds?
It won't affect your internet speeds. -Blacksoxing
  • Which service providers does this work for? Does it work for Verizon/Sprint?
This works ONLY for GSM phones, i.e. phones on AT&T, T-Mobile, or most international carrier. This will NOT work on CDMA/TDMA phones, specifically phones from Verizon or Sprint. Some Verizon phones use SIM cards for 4G data, and it may be possible to use those phones with GSM networks, but I am not sure of that. -hallowmann
  • Does this mean I can use it outside the country without paying any extra service fees?
You have to pay for service no matter where you go, but if you go to another country, rather than being forced to use your AT&T SIM card with international roaming, you can buy a prepaid SIM card from the country you are traveling to. You would have to switch the SIM cards and then you can use your unlocked phone on the international service plan. -hallowmann
  • What does "GSM' mean in the original post?
GSM refers to use "Global System for Mobile communications". This is for mobile devices that use SIM cards for voice, specifically AT&T and T-Mobile devices in the US, and almost all devices every else in the world. -hallowmann
  • Does unlocking the phone mean that I am no longer under my contract? Will I still have to pay my service provider the monthly service fee? What about Early Termination Fee (ETF)?
Unlocking the phone deals ONLY with the phone, not with your service. You will still have the service and you will still either have to pay the monthly fees or pay the early termination fee, whether you have the phone or not. Again, unlocking the phone does NOTHING to the contract. The contract is for service, it has nothing to do with the phone. The phone is yours. You could sell the phone and you'd still have to pay your voice and data service. -hallowmann
  • Does this work on the Samsung Galaxy S2? Other GSM phones?
It doesn't work on the S2, but if bought the phone (or any GSM phone) from AT&T or T-Mobile and you've had your phone for something like 90 days or 6 months (not sure which) with service, you can call them up and say you are going overseas and need to unlock your phone for use there. They should give/email you the SIM unlock code for your phone, which you would need to put in when you insert another network's SIM into your phone. If they give you trouble, just keep pressing that you may go to areas that don't have their coverage and need other options. They should/will give it to you. -hallowmann[LIST]
  • Foreign sim Data plan is not working
Add APN settings as per new foreign sim provider.Prem (thanks to lillazyfats81



UPDATE:
It doesn't work with custom rom, at least for CM10 rom. you must restore the original rom to use the code.



No go on unused VZW GS3 (I know it's not GSM, still gave it a shot); Code didn't work (Stock ICS)
VZW GSM always works overseas, you don't even have to unlock it - http://forum.xda-developers.com/s...?t=1809314

Just to clear up some of the questions being asked frequently
This is the main reason to unlock. Means you can move your phone plan to another carrier and take your phone with you without buying another phone. Another reason is for travelling and using prepaid sims from another country.

tried and got " no connection or invalid MMC code" on my AT&T S3.
Same. Got that popup afer dialing the # code.

Even if you unlock it you are still stuck with the 2 years contract and you won't be able to switch carriers which is the main reason to unlock a phone.

True, the unlock is only useful for people going out of the country and using overseas a local SIM.

Anyway, I got my unlock for the S3 very cheap on ebay.

In my case, I will be traveling overseas next month and wondering if I can gift this to someone. Not sure if I have to pay early termination fee ($325) for AT&T even if the phone gets unlocked
