I'm pretty sure you can only do it from the stock ROM with the different SIM card.

The unlock code will only work with a foreign SIM.

What? Did you not read the second post? "MUST BE ON STOCK ROM!"
For both the MMI code to work and for the non branded sim card to work. STOCK ROM ONLY. K?
Flash STOCK ROM via ODIN.
Instert sim card.
Boot up.
Enter unlock code.
Confirm its working (I just called my house)
Flash whatever ROM you have as your DD
Enjoy.

Im assuming stock rooted is OK? Or does the phone need to be unrooted?

Stock rooted is fine. It just has to be stock because the custom ROMs dont have the proper coding necessary for the unlock prompt to appear.

Can't unlock my phone.

Hi all,
I tried to unlock my phone with the code provided by cellunlocker.net and no luck.
Method 1: when I insert my t mobile card, it doesn't ask for an unlock code( it should cuz this is a non art sim card right?)
Method 2: after punch in #7465625*638*(my unlock code)#. Nothing happens. (It should say something like unlock successful or not right?)
Heck even I can't check the lock status of my phone. I type in *#7465625# and didn't bring up anything.
Method 3: i type in #7465625*638*# and wait for it to ask the unlock code. It did nothing. Didnt ask for anything.
How can I enter my code if my phone doesn't ask for it. And it locked cuz i can't use t mobile sim.when I inserted t mobile sum it says no sim card.
Plz help. Any ideas or advice would be greatly appreciated.
My phone is att i747. 4.0.4. Baseband i747uclh9.

I used the following on my S2, when I did, I am pretty sure I saw an option for the S3 as well. Might be worth a shot.

Also, are you on a stock or custom ROM? I've read that that can be a variable as well.

Thanks for the response. My phone is running stock ICS.
THe thing that bugs me most is that it doesn't prompt the network unlock screen, hence I can't enter my code.
The link you sent me apparently works for the att s2 sadly.

I wouldn't even waste my time with cellunlocker.net I bought an unlock code from them tried ALL the methods they gave you in the email and they didn't work I eventually took it to a cell repair guy locally and he unlocked it for me for 15 bucks and it was a factory unlock like it would be sim free
Galaxy SIII via XDA premium

I think I will root and put a rom only phone and try the unlock code again. Otherwise I am now having a paperweight.

What I meant was....in the app itself, AFTER I downloaded it from the Play Store, there is a tab to select the S3....inside the app. Did you actually download it and look at it? Just checking.

Doing a NAndroid and I am going to try this. What sucks is I don't know anyone with a micro sim from Tmobile here at work
EDIT
Didn't work, would not/could not save EFS folder from step 1.

I've run into the same issue here only I got my unlock code straight from ATT. SGSunlocker won't save the efs (even though it's in the save location it doesn't register as being saved) so it won't go to step 2. The unlock code entry sequence you mentioned doesn't work either (that's what ATT gave as well).
Haven't tried a tmobile sim yet though, just got the code yesterday.

Unlocking phone with code on custom ROM (CM10)?

Is there a way to unlock the phone when running a custom ROM such as CM10? Is it permanent whether or not I flash other or upgraded ROMs in the future?
I am asking all of this knowing my unlock code. I got it from my carrier but when I use the secret GSIII codes along with my unlock code I get an error. I assume its because I am on CM10. Is there a way to do this without putting another SIM in my phone.
I am asking this because I want to verify my unlock before traveling and getting a foreign SIM inserted.
Thank you.

I've had this issue myself. You must unlock on stock rom or else it won't work.

Even if you're on the stock ROM, the code that you type in to get to the unlock prompt won't work. The only way to do it is to insert another carrier's SIM &turn on the phone. It will then prompt you for the unlock code. Type it in and voila.

Oops the previous poster added info I forgot to add! Stock rom + another carrier's SIM card and you're good to go! The other carrier's SIM doesn't even have to be active or if you don't have another SIM, you can easily pick up a prepaid SIM for about $5-$10.

So after unlock flashing ROMs will still have it unlocked right?
Also for my reference, for those in the US, will a T-mobile micro SIM prepaid card that I can buy can be used to verify my unlock on my AT&T Samsung GS3?
Thanks.

Yeah. Any SIM will verify it. And yes, when it's unlocked, it's unlocked. No matter what ROM you flash, it will be unlocked.

third time is a charm! After two tries it finally worked for me. this time I made sure that I called at a time that it would be hard for me to get a US rep(2:00 AM EST).
This time I got a mexican rep, she was so nice and fast. no questions asked, just the IMEI and 3 minutes later she gave me the code. Also, I am on CM10.0.0 stable and it worked by just putting a alien SIM card and entering the code.

Unlocking ROM'd Captivate?!
So, with your note below you are saying that even with another ROM you can unlock a phone, say the Captivate(i897), by just getting a friendly non-US based AT&T help desk person!?

Unlock your ATT phones?

No credit to me, . Was just browsing the international forums and came across this:
http://forum.xda-developers.com/showthread.php?t=2014982
Apparently it works for ATT folks, tried it on my rogers phone it didnt work. If it worked for anyone here please let me know. Also please thank the original threader if it worked.
EDIT: I think this works on rogers too. I forgot to INPUT THE * before the # , i didnt see that. ahaha.! Wow it cant be this easy!
2nd edit: confirmed working on rogers, telus, atnt, mobilicity, telus, bell

I just did it, will try and put in a different sim when I have a chance.

1- Before the procedure I installed an old inactive T-Mobile SIM card and was asked for an unlock code after the lock screen.
2- I powered down the phone, reinstalled my active AT&T SIM card and did all the steps mentioned in the other thread. First time I din't see one of the screens (the one prior to hitting back) so I did it a second time and all was according to the instructions.
3- I rebooted with the AT&T SIM card and then I shut the phone down again.
4- Inserted the same old inactive T-Mobile SIM card used on first test and I wasn't required to enter any code like it did before!
I cannot test any further because I don't have access to any other active SIM Card!
Lets wait and see if it was really that easy to unlock :highfive:

Did the steps on my Bell phone and put in a telus sim and it worked.

badass, worked on mine! (didn't check to see if it was already unlocked, though...)

This is really GREAT NEWS ...
Have anyone tried to see if it still works after the FACTORY RESET.

Worked for me. On Rogers

Confirmed working for telus sgh-i317m.
Thanks! You deserve some credit coz I barely go through the international version thread and I would have never found this method if you didn't post it here. Of course the other guy gets a Thanks and a beer from me but you get a click on your Thanks button for reps!

I did it a couple of days ago. Tried it with my O2 pay-as-you-go SIM from the UK. The GN2 got a signal and connected to the network, so it does work. In the past, I got the screen asking for the unlock code.

Can someone try this link and tell me if it says unlocked?

I tried this on an AT&T Note 2 (SGH-I317) and it worked for me. I put a T-Mobile sim in it and it did not ask for an unlock code. Thank you guys!!!

That link seems to only check iPhones. I think the more important piece is that the phone accepts and works with non-AT&T SIMs. That pretty much means it's unlocked.

Yep. Worked for my on my SGH-i317. I stuck in an inacitve Verizon SIM and no promoting for unlock.
So one thing I noticed is Settings -> About -> Status ... At the very bottom it says: Device Status: Modified. I never noticed this before ... Did that just appear? My phone is bone stock and has never been rooted or modified other than the unlock procedure.
Can someone else look at this before and after? I may go to the ATT store and unlock a display model to test...

Unlock Code From AT&T Not Working - What Can I Do? [HELP]

I was given the unlock code and it still says request to unlock network unsuccessful, it's eligible to be unlocked...
All help would be greatly appreciated.

Should I try flashing over back to this stock rom and then see: http://server10.stockroms.net/download/GalaxyNote2/SGH-I317/I317UCALJ2_I317ATTALJ2_ATT.zip
I hate being stuck in a rut like this, already had my account transfered to a T-Mobile microsim. This is driving me nuts...
The person I bought this phone from said they updated but then when I checked it was still at 4.1.2 and said something about update interrupted...

Or which of these should I use: http://www.scottsroms.com/downloads.php?do=cat&id=71

Flashing a Rom won't unlocknyour phone..... Also what do you mean your still on 4.1.2?? That is the latest Rom for the phone. ... Where are you obtaining your unlock code from? The only time att provides it themselves is over the phone. You sure your not getting the wrong code?
Sent from my Xperia X10 using xda app-developers app

Yes I got the code from AT&T over the phone, called them twice and got the same code 1-800-331-0500 they gave me 41907314... According to this: http://galaxynote2root.com/galaxy-note-2-tutorials/how-to-unlock-sim-for-free-on-gsm-galaxy-note-2/ if ya take the newest update, ya can't sim unlock the phone cause it takes out the “NW Lock NV Data Initiallize” (Step #9) according to YouTube user comments...
THIS IS WHY I'm wondering what Stock firmware I need to downgrade back to in order to get that option again and be able to sim unlock my phone.
So I'm wondering if it's I317UCALJ2 or I317UCALK7 that re-enables that option for me. Right now I'm on I317UCAMA4...

I'll be having to do it all over again too, by the end of this week possibly, since some jerk decided to steal my note 2 I had to go to ebay and win a new one.
I don't think it'd matter during the Odin flash with a AT&T sim card or T-Mobile one in it, I can't remember if I did it with or without a sim card, but to be on the safe side I'd do it without a T-Mobile sim card in it, just for that first successful boot... Then do the 4.1.1 unlock code method, take the back and battery off then pop in the T-Mobile sim card(Or whatever other non-AT&T carrier sim card) and see if it done it correctly...

I bought an AT&T live demo note 2 that was used in an AT&T store. I used this method from youtube, popped in my niece's T-Mobile microsd and dialed 611. T-Mobile's customer service rang and answered showing it worked. You need 4.1.1 to use this method though. I'm going get me a microsim today since my vibrant doesn't use the micro.

The above is not true - if your phone has upgraded firmware, you will NOT see the item "NW LOCK NV RAM...." in your "NETWORK LOCK" "PHONE CONTROL" menu.
So, the ONLY two solutions are:
1) keep bugging ATT to create a case for you and investigate
2) downgrade to 4.1.1 modem (NEED TO READ/UNDERSTAND HOW TO FLASH etc.)
then apply the Samsung service menu "fix" as shown in the above video...*
*Then, you could upgrade to newer ROM... if you wish....:cyclops:
