[Q] Cannot unlock AT&T GS3 with unlock code - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

I bought a ATT Galaxy S3. The seller called AT&T and got the unlock code. I popped in a Simple Mobile sim card and it says "SIM network unlock pin". I then entered 8 digit unlock code got from AT&T. But it did work. Still asking for sim network unlock pin.
Has anyone had same problem. Is Simple Mobile causing this problem, since it's a prepaid network? Do I have to use one of the big GSM networks sim card to unlock first then use Simple Mobile sim card?
Any help would be highly appreciated.

try this
it worked for me on my 2nd s3 running 4.0.4 stock ics (just got) =)
make sure no sim card inside the phone yet, if there is, just take it out
Dial *#197328640#
Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > (after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in [6] Network Lock then choose [4] NW Lock NV Data INITIALLIZ ..... wait for a minute then reboot your phone...
there won't be any confirmation just reboot your phone, put your sim back in, wait for about 10-30 seconds for your phone to pick up the network and kabaaam it is unlocked, the timing is important btw

Make sure the IMEI used to get the unlock code is 100% correct.
Secondly, if the phone has had previously failed unlock attempts on it, you may need to use a Defreeze code to reactivate an unlock attempt. The phone may be rejected the unlock code (even if correct) because of this.

Strange. I thought this was only for 4.1.1. It didn't work on my wife's 4.0.4 but worked on my 4.1.1

Without a SIM, my phone will not dial this code. I've read that if I just try thee Unlock code all 10 times, on the 11th time, it will work. Some Windows Phone forum said that worked for several people.

found this online and it worked for me

No. I have tried the unlock methods on the web that work for Android 4.1.1 on the AT&T Samsung i747, and they do not work on Android 4.1.2. I have been unable to find any accurate directions for unlocking this version, but there are apparently lots of people who will misdirect you to the old instructions for the previous version.

Unlock galaxy note 2 (easy steps)

All you have to do is enter a code from your devices’ menu; there’s no need to send information to a website, pay anything or wait for an unlock code.
Note that this method may not work for all Galaxy S III or Note II variants. Also keep in mind that this could void your warranty, so proceed at your own risk. Here are the steps you need to take:
1) Insert the desired SIM card you want to use unlocked into your device, and restart the phone.
2) Enter the code *#197328640# into the keypad and press send.
3) Go to 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)
4) Go back one step by pressing the Menu button, select back, which should bring you to [6] Network Lock, then choose [4] NW Lock NV Data INITIALLIZ.
If you followed the above steps correctly, your device should now work with the new SIM card!
aileori clk
i've just tried this procedure and i was able to follow and complete all the steps just waiting to try with a different sim card. phone supplied by tmobile, have not faced issues as others have in other posts where some of the menu functions were not visible. will update when have tested with different sim card.
i dont get that last step [6] Network Lock, then choose [4] NW Lock NV Data INITIALLIZ.
the NW Lock NV Data INITIALLIZ doesn't show up what could it be ? is it because i did the update to 4.1.2 ? Help Plz

I just tried, and I also don't have UMTS.
But I have "Debug Screen" in the main menu and all other menus below.
Did you try with a 4.1.1 stock firmware?

I'm new to this forum too, and here:

I found a lot of informations that could also help you. You have to root your phone and flash a stock firmware without lock as Memphis_ suggest, these guides lead you to unlock your phone (and more...).

[Q] Unlock AT&T Galaxy S3

I tried to use the following route several times to unlock my GS3 with no luck. It is still saying no SIM Card. Any other ideas on what I can do?
Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > (after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in [6] Network Lock then choose [4] NW Lock NV Data INITIALLIZ
Thanks..
You need an unlock code if you are trying to unlock it for another network, don't know what the steps in that method you showed is about but I believe you need an unlock code to unlock it as there is no software that can unlock it yet.
Here is a topic about the available unlocks.

It might not work with AT&T S3 as it says : " Please note that due to different hardware, US Qualcomm based GS3 (SGH-T999, SCH-I535, SCH-R530, SPH-L710, SGH-I747...) are currently not supported. Don't leave bad feedback, I can't do much without one of these phones in my hands ! * "

[Q] best method of unlocking my S3 (locked to Tmobile UK)

I am going to get my new s3 which is locked to tmobile (UK). I use o2 therefore need to unlock it.
Do I need to root the phone first before i unlock or it does not matter.
Also if I unlock it, will it void my warranty with Samsung.
what is the best way/method to unlock the phone (locked to Tmobile in UK) and root the phone also.
After rooting the phone is it true you can unroot the phone to the original state.
thanks
There's a hidden dialer unlock method to unlock which does in fact work for t999 and many other variants .
Follow steps closely
1. Enter the following into the dialler: *#197328640#
2. From the menu that appears choose*
Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > (after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in [6] Network Lock then choose [4] NW Lock NV Data INITIALLIZ ..... wait for a minute then reboot your phone... enjoy!!!

Unlocking will not void your warranty, by rooting may.

[Q] Problems unlocking s3

Hey guys. You've probably had a bunch of posts like this, but I've spent the past day frustratedly searching up as much about this as possible and I still can't find an answer.
My mother gave me her old Galaxy S3 which had been network locked. I've checked the IMEI blacklist and it doesn't seem to be on 3 that you can check for free.
The phone is a UK Samsung Galaxy S3 GT-i93505, originally on contract to Orange. I used Odin and flashed the firmware from 4.1.2 to JB 4.1.1 as far as I know, so that I could unlock. Everything was successful.
I followed the numerous guides on entering Service mode > Debug > Phone Control >Network Lock > PERSO SHA256 OFF > SHA256_ENABLE_FLAG [0] SHA256_OFF=>Not Change > Current Command is 118630.
From here of course, I go back, hit NW LOCK NV DATA INITIALLIZ > PERSO_NV_INIT is SUCCESSFUL.
From here I wait, shut down, restart, enter my new sim, but nothing changes. Any network access is still locked. I've read on one forum that people have had success when they 'change' ENABLE_FLAG from [0] to [1], but i can't find any instruction on how to do this. I've also read that the process only works when the Current Command is 118640 not 118630, but after repeated tries the code will not change.
It's doing my nut in, I don't want to pay for an unlock code or some guy down the highstreet to unlock it when I see so many people doing it themselves...any help would seriously be appreciated, i'm new at all this.
Thanks!
Are you using the unlock method from this forum? If you are, it may not work as it is designed to work with the i747 and i747m.

I think the free unlock method will still work for the UK variant. The instructions are slightly different, however. Try the following steps ...
1) Put a non-compliant SIM in your device and reboot with the SIM inside. Click on dismiss when prompted for unlock code
2) Go to the dial pad and in *#197328640#.
3) Do the usual [1] UMTS => [1] Debug Screen => [8] Phone Control => [6] Network Lock
4) Options [3 ]PERSO SHA256 OFF and wait for around 30 seconds.
5) Hit Menu button and click on Back. Then Choose [4] NW Lock NV Data INITIALLIZ.
Enter *#197328640# again using the Key Input
If this doesn't work, after the first time at [3] PERSO SHA256 OFF, hit Menu => Back then [2] PERSO SHA256 ON then Menu => Back and repeat steps 4) & 5) again. You will notice that the info in [3] PERSO SHA256 will have changed.
