############################################
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:

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..

Hi one i have is locked on EE it's custom rooted tried *# code but don't work does it have to be derooted for that to work?
took it to a friends shop but he had to take to other place as his box don't deal with it but other guy said has to be unrooted first said leave it as not sure what software items it has as just got it used friends going to take to his shop to back it up can he re root from a back up? the custom rom said something with india in it when looked in menu about phone and says 4.3.
did speak to guy got phone from going to ring EE to see if can unlock as said it's off contract now so what would be best way to go?
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!!

Do you know if it's purely software based? I'm wondering if one was to flash a custom rom if that would affect the unlock.

I did this on my 1713 but don't know if unlocked. Should it tell you? I don't have another sim.
Just tried it on my AT&T Note II with a T-Mobile SIM and didn't ask me to provide a unlock code after doing the above OP instructions. Before trying the unlock method I turned phone with T-Mobile SIM and it asked for a unlock code.
Now will try it on my Galaxy S III running Jelly Bean.

Thanks for digging this long buried thread up just to tell us that...?
I could be wrong but I believe it would still be legal if the phone was bought before the law went into effect. At least that was my interpretation.

Correct
And if you're no longer in a carrier contract, is it also illegal to unlock?
Nope then the phone is yours ...I think....its just when u owe them for the phone

Some people believe that you still need to get permission from the carrier to unlock the phone to switch to another service even if your contract is over.
Here's a link to the docket for you legal buffs/lawyers who want to translate it for us:
https://s3.amazonaws.com/public-inspection.federalregister.gov/2012-26308.pdf
Frankly, it's not going to stop people, and it's going to take a lot for cell phone companies to enforce such a thing. There are people out there, such as Craigslist, who buy new phones and renew their contract, but continue using their old phone and simply turn around and sell their new phone at full price.
i have the AT&T Samsung Galaxy S3 SGH-I747. the phone is already unlocked so i know it should accept foreign sims but it doesn't recognize any sim i put in it. so far ive used 3 different simple mobile sims and none of them have worked. i called AT&T to find out if my IEMI was blocked or blacklisted but they said no, the phone should be working perfectly. plus weird thing is, i get the signal bars next to the battery as if the sim is working but it still says "No Sim. Insert Sim Card"
the phone is rooted so i was wondering maybe that has something to do with it? the phone was working perfectly fine until i rooted it. the specs are:
Android Version: 4.1.1
Baseband Version: I747UCLEM
Kernel Version: 3.0.31 - 274808
Build number: JRO03L.I747UCDLK3
please i am very desperate to get it working by tonight. does anybody know why my galaxy s3 won't recognize any simple mobile sim put in it? is there software im missing or updates i need? i already tried unrooting my phone, no luck.

yes the phone is unlocked. maybe i forgot to mention this earlier but it was using a simple mobile sim card perfect before i rooted it. i called AT&T international and they gave me the unlock code after i asked. i didn't need it tho because they told me if it wasn't unlocked, after i put the foreign sim in, it would prompt for the unlock code but the phone never prompts for one, just says "No Sim insert Sim card", something along those lines. further more i was informed that if it wasn't unlocked, it would say "unrecognizable sim" instead of "no sim". the fact that it says "no sim" means it won't read the sim card. the thing is no matter what sim card i put it (i tried 3 or 4 different ones) the phone still says "no sim"
i tried changing the modem to every single one compatible with the SGH i747 model and nothing helped. i tried changing the modem to a Tmobile modem because i know simple mobile uses Tmobile radio towers but that didn't help at all. i deleted all the cache and unrooted the phone but that didn't help so i rerooted it again. i don't know im just extremely frustrated right now. i've spent hours on the interenet and called AT&T international countless times to try and fix it but they always tell me its the sim cards fault but i know its not because i've tried it in other phones and they work. i'm just looking for a miracle here.
oh i did try to flash a custom rom and kernel but it didn't work and i received an error message and rebooted it without tampering with the rom and kernel again. maybe that has something to do with it?
Try doing a kies factory restore mate.

Same Problem
Sadly to say I have the same problem but on a new Samsung Galaxy Note 3 N900V. I bought it online and it was supposed to be factory unlocked but it doesn't work on Fido, koodo, or bell; so I am not sure if it is factory unlocked. It says No SIM on all three sim cards. I tried rooting and it is still the same. I don't know what's wrong but I tried contacting Verizon who is the carrier of the phone but you can't get help unless you have a phone plan with them. And then I want to be using this on koodo and they won't help you because the phone is not from them. I am going crazy, anyone know how this can be fixed.

What ROM was on your phone? Is it the i747 or i747m? The thread you linked is for the international version of the Note 2.
hey guys, this is my first post on xda. Ive owned almost every galaxy phone in the series since the S2 and every time i have any questions, i refer to your site to search for an answer. i have found my solution every single time until now. i have tried searching left and right and feel like i have been so close to solving my problem then i find a new problem. heres my situation.
i have a note 2 from US cellular in the US which is CDMA. im traveling to Paris (currently in paris now) and i bought a new Note 2 that runs on GSM. now my problem is that the phone is carrier locked to a korean phone company. I posted this in the ATT section because i could not find a section for my phone model and many of my close solutions referred to using ATT firmwares so i felt this was the closest section.
my phone info:
Galaxy note 2
model: SHV-E250S
Android version: 4.1.2
Device status: normal (unrooted) (i have my US cellular note 2 rooted through one button method and can probably do that to this phone as well if needed, so if you have a solution that contains root access please know i can still go that route!)
so to carrier unlock this phone i read about this easy method:
Step 1: On your Galaxy Note II, launch the phone app and press these keys:
*#197328640#
Step 2: From the Main Menu, navigate to [1] UMTS > [1]Debug Screen > [8] Phone Control > [6] Network Lock > Options.
Step 3: In the Options screen, choose [3] Perso SHA256 OFF. Wait for 30 seconds after making this selection.
Step 4: Go back one step by pressing the menu key, and then back once. You should now again be in [6] Network Lock
Step 5: Here, now choose [4]NW Lock NV Data INITIALLIZ. Wait for one minute after making the choice.
Step 6: After a minute has passed, reboot your Galaxy Note II.
but my problem is that when i enter that first code i get this message: "connection problem or invalid MMI code."
so i searched how to resolve that. i found some threads saying that i need to downgrade my firmware to 4.1.1 because 4.1.2 blocks this on some phones. so i looked into downgrading my firmware. Went to samsung-updates and entered my device model and they only had 4.1.2 firmwares. i didnt try an ATT firmware because im not confident it will work so if i can get assurance that it will ill try that route.
from there i also googled my model and firmware 4.1.1 and found nothing.
somewhere in all this i also was told to change my csc as well. I tried doing that with the code provided online and received the same error message. i would like to change the csc so it runs on UK csc as well.
sorry if anything is confusing, im not a huge tech guy when it comes to phones, but i try. I dont know how to flash roms or anything, only reason i ever rooted a phone was to use free tethering.
in conclusion, i just simply want to carrier unlock this korean note 2.
any help is appreciated as i would like to get a phone plan here in france asap but i want to make sure this phone is going to work. I dont even know how to check if its carrier unlocked after i do succeed in this. i have access to a tmobile sim card if needed to check.
thanks in advance and thanks to everyone who has helped others on this site. i have used your expertise many times in the last few years and now finally i can say thanks for the great information!
I am selling my SGH-i317, but am unable to SIM unlock the phone with the unlock code that AT&T provided for the IMEI.
When pop in a T-Mobile SIM, the phone asks me for an unlock code. But it refuses to accept the code with message: "Network unlock request unsuccessful".
What could be causing this?
Here's a history of my phone:
1. I have used it with a custom ROM, so the KNOX counter is tripped.
2. I was on a rooted UCUBMK6 ROM with TWRP recovery.
3. I used Triangle Away and unrooted.
4. I then used Odin to flash back to UCALJ2 with Stock Recovery (unrooted), using this tar file: KIES_HOME_I317UCALJ2_I317ATTALJ2_215287_REV04_user_low_ship.tar.md5
5. This gave me stock recovery and stock ROM. KNOX still tripped, custom ROM counter=1
6. I then used Odin to flash the UCUCNE5-Stock-No recovery. I assumed that the stock recovery from the UCALJ2 ROM would work as a "match" (?).
7. Device now reports baseband version I317UCUCNE5, build number KOT49H.I317UCUCNE5. Kernel 3.0.31-1728680. KNOX still tripped, Custom ROM counter=1.
But the unlock is a no-go. What gives??
Have you tried the before method?

No..thanks for the tip. My menu doesn't show that option, probably removed in later ROM versions. But I found this YouTube video that suggests flashing back to an older modem, then following that method, then flashing back. Worth a try...will give that a go.
This helped me unlock my device....

It was probably mine. I had the same issue and I got my code from cellunlocker.net.
I was on SlimRom and it was not working. I finally went back to the official rom for one final try and it worked.
This is what I did. I'm not sure if just trying the unlock code would've worked but I did follow these steps (it's a bit weird since you don't actually change anything, maybe it forces the phone to refresh something.)
Just make sure you are on official ROM or it won't work (I tried only the code with the SlimROM and it did not work).
After unlocking I went back to SlimRom and then CM and it was always unlocked.
1. Make sure that the phone PROMPTS for the code with a NON accepted sim card and that your IMEI is correct by dialing *#06#
a. Go to the Dial pad and dial *#197328640#
b. Please click on number [1] UMTS > [1] Debugging screen > [8] Phone Control > [6] NETWORK LOCK
c. You will see 3 options
d. Please click on number [1] Perso Sha256 INFO, the screen will change slightly
e. Please hit the MENU button then when the menu pops up please carefully hit BACK to return to the previous screen
f. Next Please click on number [2] Perso Sha256 ON, the screen will change again to a one line message
g. Restart the phone on the screen by holding the power button and click RESTART
h. When the phone prompts for the unlock code simply enter the unlock code provided to you
i. Your phone is now permanently unlocked!

This method worked for me.
FYI- my situation (maybe it'll help others): I bought a T-Mobile prepaid SIM card for my spare GS3 just to see if it would work. I contacted AT&T and they provided me a SIM unlock code (took about 2 days). However, it did not work! 5 days later, and they still haven't figured it out! I decided to take matters into my own hands. After many many hours of research and trying all sorts of methods I believe whats happening its that people are trying the dial pad method and setting their Perso Sha256 to "OFF". If you've done that then unlock codes will not register correctly... So get and unlock code, then set it back to ON following the steps above. Hopefully that helps others..

Hello,
I've had a long saga of failures trying to unlock my T-Mobile Samsung Galaxy S III (aka sgh-t999). Firstly I started by trying to convince T-Mobile to give me the code but they gave be the bureaucratic cold shoulder for a year. After threatening to cancel they finally produced an incorrect SIM unlock code for me from Samsung. I tried it and it failed.
I then took my phone to one of those shady SIM unlock places in London and paid them to do it. After a day of waiting they sent me an email of the same, incorrect SIM unlock code which again failed to work.
I decided to try a common method I found all over tutorials that works as follows.
Go to the dialer
*#197328640#
[1] UMTS
[1] DEBUG SCREEN
[8] PHONE CONTROL
[6] NETWORK LOCK
[3] PERSO SHA256 OFF
Wait 30 seconds then press Menu and back
[4] NW Lock NV Data INITIALLIZ
Wait 60 seconds then reboot
Sadly no matter what I do that last menu option simply does not exist on my phone.
This fails on Android 4.1.2 which was on my phone when I started so I recently got a stock 4.1.1 ROM which the tutorials said was necessary. So I rooted my phone, installed ClockworkMod recovery so now when I go into recovery mode I get that CWM. I then used that to install a pre-rooted 4.1.1 build and tried to do the above SIM unlock method and it sadly it failed again in the exact same way. Option 4, NW Lock NV Data INITIALLIZ does not exist.
Does anyone know of anything I can do to SIM unlock my phone? Anyone know of any specific links to firmware and or OS ROM images that they know installs an OS that this works on? Are there apps one can run as root that will unlock? Remember I can't use anything that goes through Samsung because it ends up being incorrect.
Thanks for the help.

Your rom version has nothing to do with it. Your modem must be 4.1.1, but it wont work if youve ever updated to 4.3.
The code you got is not wrong. Especially if you got the same one from two sources. Its based on your imei so every decice has its own unique unlock code.
There's a thread in AT&T forums where someone posted a way to get it to work if having problems. Its at the end of an unlock thread in the General section I think. See if you can find and try that.
Hope it helps.

Can anyone explain to me what the 4.3 update does that stops this unlock proceeding? Surely the update can be removed.
