First, sorry if sim unlock has already been achieved. I searched every where and couldnt find a solution. I have a galaxy S3 T999 US version. I was able to sim unlock my device by doing a couple of things.
I downloaded and odined a rooted 4.1.1 stock found here: http://forum.xda-developers.com/showthread.php?t=1771687
I then booted up the phone after it was finished and did an ota software update.
I the followed these instructions found here on xda:
Go to dailer screen. press *#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... enjoy!!! There is no confirmation on the phone that the unlock was successfull.... just reboot your phone....
To test, just insert a sim card from a different carrier/provider. If the new sim card works then your phone is now unlocked.
Please note that until i installed the rooted stock 4.1.1 rom and did an ota update some of the above options were not available so i was not able to attempt the sim unlock. Also, after you do the ota update, you will lose root, but you will be sim unlocked. You can try odin the rooted stock 4.1.1 and before doing an ota update try the steps first to see if the menu options are there, i never did, so i dont know.
If this works for you, please post back
This is very old for us. We already have a thread for this in general section.

Btw you dont need to be stock to unlock phone; I did unlock while I was in wicked ROM. So who wants to try this try first in your ROM if not then only go through all process.

You need to at least have the Touchwiz framework for it to work. If your on AOSP like Cyanogenmod it won't work
I have this phone I want to unlock for my carrier (T-Mobile)
AT&T gave me an unlock code that did not work. We tried it more than 5 times and AT&T says that it is permanently locked to AT&T.
Is there a way that I can get this phone unlocked?
Thanks.
give this a shot

It doesn't work on 4.1.2. Make a backup, then use Odin to go back to 4.1.1, then unlock using this method, then upgrade back to 4.1.2 and/or restore backup if you wish.

Thank you.
I have finally come to that decision through my research. My issue now is finding the right version of Odin (I think 3.07 is the latest) and the correct version of 4.1.1 for my phone.
yes is very nice solution

Worked perfectly. Stock Bell SGS3.
Now, it wasn't stock to begin with - I was running Task650's AOKP on it. Of course the instructions didn't work on that so I flashed a stock Bell ROM onto it then it worked perfectly. Phone unlocked on the first try.
Some of the menu items weren't exactly in the same place but they had the same names so no problems finding them.
Thanks!

Do not attempt this downgrade if you have upgraded to the official 4.3 ota. It will brick your phone.

Once done you can upgrade to any firmware you want as it is a permanent unlock. Also if you downgrade from 4.3 i dont see why it would brick, but if the admin says so then i believe it.
You should probably put a large RED warning in the first post that if they down grade from 4.3 to 4.1.1 to unlock they will hard brick. Specifically flashing the 4.1.X bootloaders cause the brick.
also on 4.3 this appears to work and retains sim unlock SHA256 OFF

Downgrading from 4.3 is guaranteed to hard brick the phone. As Mr. X says please make note with giant warning at beginning of first post. This will break phones and people need to know.

I did mine a long time ago. After reading quite a bit you may be right for the time being. The best I have found without a risk of a brick is this:
There is a lot of confusion about unlocking in this thread and elsewhere. Your S3 can still be unlocked after the 4.3 update, just keep in mind that most threads either have inaccurate information or miss essential steps.
Unlock codes and procedures often change or play musical chairs in major software updates. Prior to the problematic 4.3 update you could unlock your S3 with the cited procedure in this thread. This is a permanent unlock and would survive firmware changes. This only applies to touchwiz ROMs e.g. North American factory ROMs or custom ROMs that preserve the dialer codes. This unlocking procedure is also distinct from the carrier specific unlock codes or commercial unlockers who either have access to the official database or have figured out the key algorithm.
If your phone has not taken the 4.3 update yet:
Install the 4.1.1 stock touchwiz ROM and use this procedure to unlock. You can then revert back to your favourite firmware version after your phone has been unlocked.
Dial the following code on the phone keypad: *#197328640#
Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF
After choosing this option, wait 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 INITIALIZE
You should see a message that says
SHA256_ENABLED_FLAG[0]
SHA256_OFF => Not Change
Choose [1] SHA256_ENABLED_FLAG
Wait 30 seconds, then press Menu > Back. Do not use the back key, choose back from the menu popup.
You should now see a message that says
MENU NOT EXIST
PRESS BACK KEY
Current Command is 118640 (if you don't see this message.. skip to alternate step below)
Note that the exact Command number may vary.. don't worry about that.
Wait another 30 seconds, then press Menu > Back. Do not use the back key, choose back from the menu popup
You should see a message that PERSO_NV_INIT is processing, then PERSO_NV_INIT is SUCCESSFUL
Now return to the SHA256 menu and turn Perso SHA256 back on
Back our of all menus and enjoy your unlocked S3
Alternate step. If you didn't receive the MENU NOT EXIST message, then use the back option in the menu popup until you see a menu what includes [6] Common.
Click on [6] Common and choose [6] NV REBUILD
You should now see a message that says:
Golden-Backup exist
You can Restore Cal/NV
Choose [4] Restore Backup
Your phone may freeze or change screens briefly, then should reboot
If you run into errors, look at this link for advice on how to proceed: How to unlock.. (techbeasts.com)
Enjoy your unlocked S3
If you have the 4.3 update:
Now you know that updates are evil or at least mess up your plans.
The unlock procedures have changed somewhat now and it seems that there are now several alternate procedures depending on your carrier.
Gambit #1
If you tried the above and got half way to find that menu item [4] NW Lock NV Data INITIALIZE was missing, then try the following. Note that menu item [4] may also be missing if your phone is already unlocked. So you might want to try a SIM from another carrier to confirm whether your phone really needs to be unlocked.
Dial the following code on the phone keypad: *#197328640#
Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF
After choosing this option, wait 30 seconds, then go back one step by pressing the Menu button then select back
Now you are in [6] Network Lock and presumably you now find that there is no [4] NW Lock NV Data INITIALIZE menu item
If so, then press Menu > Back. Do not use the back key, choose back from the menu popup.
Now this is the step that most threads miss, tap on SHA256_ENABLED_FLAG.
This item may look like a message rather than a menu choice i.e. may not be enumerated. Tap it anyway
Now you may see one of several things.
If it appears that you are back to the starting menu, choose [1} UMTS again and follow the original steps and you should find that the missing menu item is now present, although it may be labeled NW Lock NV Data INITIALIZE or NV REBUILD. Or you may find yourself on a page that already has the initialize or rebuild option.
In either case, choose INTIALIZE or REBUILD, followed by the remaining steps as originally described.
If you get a message asking you to reboot your phone to finish, then do that instead of the remaining steps.
I'd recommend that after you are done that you return to the service menu again and ensure that SHA256 was re-enabled. The SHA256_ENABLED_FLAG should = 1 (not 0). If the flag status is 0, then choose the Perso SHA256 ON option.
Enjoy your unlocked S3
Gambit #2
If the above does is still missing key menu items on your phone, then try this alternate dialer code:
*#27663368378#
And then proceed as before.
However, if you encounter the following message:
Golden-Backup exist
Then follow the procedure in this link instead: How to unlock.. (techbeasts.com)
Enjoy your unlocked S3
Gambit #3
If you still have a stubborn phone, try the following dialer code

Oh no.. that didn't work either!
If all else fails, contact your provider and tell them that you will be traveling in elsewhere e.g. Europe and need to have your phone unlocked. Most carriers will provide you with a network (carrier) unlock code in this situation. Typically without charge, but it will vary by carrier. Or you can avail yourself of a commercial unlocking service. Google will find a googol [sic] of them for you.
Note that you need to insert a valid, non-blacklisted SIM from another carrier to be prompted to enter a network unlock code. It need not be active, just not blocked i.e. reported as lost /stolen. If you have any difficulties entering the code, have a look at this link.
Good luck

I did mine a long time ago. After reading quite a bit you may be right for the time being. The best I have found without a risk of a brick is this:
There is a lot of confusion about unlocking in this thread and elsewhere. Your S3 can still be unlocked after the 4.3 update, just keep in mind that most threads either have inaccurate information or miss essential steps.
Unlock codes and procedures often change or play musical chairs in major software updates. Prior to the problematic 4.3 update you could unlock your S3 with the cited procedure in this thread. This is a permanent unlock and would survive firmware changes. This only applies to touchwiz ROMs e.g. North American factory ROMs or custom ROMs that preserve the dialer codes. This unlocking procedure is also distinct from the carrier specific unlock codes or commercial unlockers who either have access to the official database or have figured out the key algorithm.
If your phone has not taken the 4.3 update yet:
Install the 4.1.1 stock touchwiz ROM and use this procedure to unlock. You can then revert back to your favourite firmware version after your phone has been unlocked.
Dial the following code on the phone keypad: *#197328640#
Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF
After choosing this option, wait 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 INITIALIZE
You should see a message that says
SHA256_ENABLED_FLAG[0]
SHA256_OFF => Not Change
Choose [1] SHA256_ENABLED_FLAG
Wait 30 seconds, then press Menu > Back. Do not use the back key, choose back from the menu popup.
You should now see a message that says
MENU NOT EXIST
PRESS BACK KEY
Current Command is 118640 (if you don't see this message.. skip to alternate step below)
Note that the exact Command number may vary.. don't worry about that.
Wait another 30 seconds, then press Menu > Back. Do not use the back key, choose back from the menu popup
You should see a message that PERSO_NV_INIT is processing, then PERSO_NV_INIT is SUCCESSFUL
Now return to the SHA256 menu and turn Perso SHA256 back on
Back our of all menus and enjoy your unlocked S3
Alternate step. If you didn't receive the MENU NOT EXIST message, then use the back option in the menu popup until you see a menu what includes [6] Common.
Click on [6] Common and choose [6] NV REBUILD
You should now see a message that says:
Golden-Backup exist
You can Restore Cal/NV
Choose [4] Restore Backup
Your phone may freeze or change screens briefly, then should reboot
If you run into errors, look at this link for advice on how to proceed: How to unlock.. (techbeasts.com)
Enjoy your unlocked S3
If you have the 4.3 update:
Now you know that updates are evil or at least mess up your plans.
The unlock procedures have changed somewhat now and it seems that there are now several alternate procedures depending on your carrier.
Gambit #1
If you tried the above and got half way to find that menu item [4] NW Lock NV Data INITIALIZE was missing, then try the following. Note that menu item [4] may also be missing if your phone is already unlocked. So you might want to try a SIM from another carrier to confirm whether your phone really needs to be unlocked.
Dial the following code on the phone keypad: *#197328640#
Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF
After choosing this option, wait 30 seconds, then go back one step by pressing the Menu button then select back
Now you are in [6] Network Lock and presumably you now find that there is no [4] NW Lock NV Data INITIALIZE menu item
If so, then press Menu > Back. Do not use the back key, choose back from the menu popup.
Now this is the step that most threads miss, tap on SHA256_ENABLED_FLAG.
This item may look like a message rather than a menu choice i.e. may not be enumerated. Tap it anyway
Now you may see one of several things.
If it appears that you are back to the starting menu, choose [1} UMTS again and follow the original steps and you should find that the missing menu item is now present, although it may be labeled NW Lock NV Data INITIALIZE or NV REBUILD. Or you may find yourself on a page that already has the initialize or rebuild option.
In either case, choose INTIALIZE or REBUILD, followed by the remaining steps as originally described.
If you get a message asking you to reboot your phone to finish, then do that instead of the remaining steps.
I'd recommend that after you are done that you return to the service menu again and ensure that SHA256 was re-enabled. The SHA256_ENABLED_FLAG should = 1 (not 0). If the flag status is 0, then choose the Perso SHA256 ON option.
Enjoy your unlocked S3
Gambit #2
If the above does is still missing key menu items on your phone, then try this alternate dialer code:
*#27663368378#
And then proceed as before.
However, if you encounter the following message:
Golden-Backup exist
Then follow the procedure in this link instead: How to unlock.. (techbeasts.com)
Enjoy your unlocked S3
Gambit #3
If you still have a stubborn phone, try the following dialer code
*#0011#
This will look like an informational screen with no menu choices.
Don't fear, the menu you want is just hidden. Continue with the steps in this link: How to unlock.. (unlockfaq.com)
Enjoy your unlocked S3

Thank you,Tried all those and non work i found this site where they charge me $6 hopefully its true
Did you by chance call AT&T and ask for it? I have had better luck with them than big red. If you have an account in good standing anyway.

I would like to know the cheapest place as well...
I tried to unlock it based on above (I am on 4.3) and no go.
I know the bootloader is locked in 4.3 but is the modem? maybe you could downgrade to the 4.1.1 modem and then unlock and reflash your 4.3?

I didn't know this. I saw several posts from XDA members that were on 4.3 and wanted to unlock their phone for free. If they can just flash the modem, unlock, and reflash the modem, that would be pretty simple.

indeed we just need a brave user to try it risking his phone's life. or someone more knowledgeable than me that already knows the answer.

Do you know anyone that has actually gone through the process of unlocking by installing the 4.1.1 modem?
I saw a post about someone doing this with a 4.1.2 rom but not a 4.3 ROM.

In another thread, an XDA member had a stock 4.1.1 ROM (modem too) running on a 4.3 bootloader and the required menu options for unlocking the phone were not present which leads me to conclude that you need to be completely stock 4.1.1, including the bootloader.

[4] NW Lock NV Data INITIALLIZ
owl74 said:
PDF file now attached...
Please read the whole thread if you can or at least the whole OP down to the bottom before asking questions as your question might have already been answered... Thank you...
############################################
Hi guys, you can unlock you N7105 via the Samsung hidden menu. [Also works with N7100 and some Galaxy S3 (SIII) variants - NOT ALL]
#############################################
I can confirm the unlock survives ROM flashing
#############################################
Before doing the instructions below, please double check your phone that it is actually LOCKED by inserting a sim card from a different carrier/provider...you may or may not leave that sim card on the phone while unlocking
Note: your phone must be running at least Jelly Bean 4.1.1 (if 4.1.1 does not work, try 4.1.0) otherwise some of the menu choices are not present
Just dial the following keys *#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... enjoy!!! There is no confirmation on the phone that the unlock was successfull.... just reboot your phone....
To test, just insert a sim card from a different carrier/provider. If the new sim card works then your phone is now unlocked.
I have done this to my other Note 2 N7105 originally locked to Orange.....
========================================
Do this procedure AT YOUR OWN RISK
========================================
To those who were able to unlock their phone with the method above, can you please post in the thread and let us know which phone model (N7100 or N7105) you have, Country and Network/Carrier your phone was locked to...... and if I have saved you some cash, please click the Thanks button or the Donate button on the left just below my name to buy me a can/bottle of Heinekken, Quilmes, Budweiser, Fosters, Tiger, Stella Artois, or San Miguel :cyclops: ...
========================================
NOTICE:
To those having "Conditional Call Forwarding" pop up message or similar pop ups appear everytime you make a call (but they disappear within a few seconds), this is normal with an old sim card, or when using a ported number. There is no restriction to calls or internet or whatever. This is confirmed by my provider when I walked in and asked them about it. They even showed me one of their sample Note 2's and S3's having the same message.
========================================
I have mentioned in my old thread that there was a pop up message that says "Conditional call forwarding active" everytime I make a phone call using another SIm card that the phone was not able to use before unlocking.
I can confirm that this was due to my Sim card. It is a very old O2 sim card that I have used for years. I have tried that Sim card on another factory unlocked phone (Galaxy i8160 bought from P4u) and it had the same message.

GT-N7100 carrier unlock not working
Ok, so I tried to post this in the appropriate GT-N7100 carrier unlock thread, but I'm too n00b 'round these parts so here I am making this thread.
So this phone was initially locked to Telus, but I'm trying to unlock it so it can work with Rogers. I already possess a Rogers MicroSIM card that lives in my S3 so I have a valid card to test. It has Cyanogenmod 10.2 installed on it, by me, which was done about a year ago. I also think, at the time, that I attempted to carrier unlock it, but I can't remember if it was a success or not. But right now, I have been tasked - again - to carrier unlock this device because it apparently doesn't work.
I now believe that to be the case, as I have my S3's SIM in it right now and the phone displays a message saying it can't connect to the network (Rogers). Yes, I have manually scanned for networks, and they do appear, but I can't connect to them. I also tried dialing *#197328640# to reveal the hidden carrier menu, but when I press the call button it says there's no mobile network...
That makes no sense, this is supposed to be an ingrained menu, why would you need a network?!
The phone's details are as follows:
__________________________
Model: GT-N7100
Android Version: 4.3.1
Baseband Version: N7100DXDLK5
Kernel Version: 3.0.64-CM-g9d16c8a, [email protected] #1 , Sun Dec 8 11:30:23 PST 2013

Could this be solved by reverting to a stock ROM? Or can I keep Cyanogenmod? Because I'd really prefer to...
If any further details are required, I'll do what I can to answer. Please, help me get this phone back to a service ready state!

Not working for N7100
After tried with 10 different firmwares including the very first one rolled out (I tried it with a full Stock including modem, boot, hidden, recovery etc)... I can conclude that this method does not work for N7100 (exynos based).
After reading the posts, I saw that no one with a N7100 reported success, everyone stuck up with the patched menu. So, I suggest to remove the N7100 in the first post since it does not work for it..

Sorry for asking this but with lots of people making topics about same topic its geting confusing.
I'm looking to unlock 2 x Canadian Note II I317M's
# 1.) Is running NH2 4.4.2 Firmware
# 2.) Is running MK5 4.3 Firmware
So can I just downgrade the modems to MODEM_I317MVLALJ2 rather than downgrading whole Rom If so how can I do this?
Only asking because some are saying you can and some are saying you can't. Sorry again for asking this. I just don't want to brick these phones. One is for my pregnant wife and one is for me as our 2.5yr old broke both of ours and got these ones second hand but they are locked. Just don't want this to be wasted money.
Thank you all xda'ers in advance

Unlocking Nokia Lumia 520
Hi, will the steps you posted to unlock the Samsung phones work on the Nokia Lumia 520?
I bought this unlocked phone in the UK and it works with sim from any UK providers, however when I take it to Argentina it won't recognise the SIM cards from local providers. Somebody mentioned that it may have something to do with phone bands, that it may be unlocked for use in Europe but not outside of the EU...I've never heard of phones bands so not sure about this. I'd be grateful for any tips you could give me.
Thanks!!
