It was working on early firmwares on Galaxy S 3 and Note 2. Samsung fixed that loophole with updates almost 2 years ago.

this is how I unlocked my AT&T S4, so it wasn't patched with the s3
I remember unlocking several Note 2s with this method, but I don't even have the same menus on my N4.

I tried this on a sm-n910t with a bad imei and it does give me the UTMS option after I type in "* #197328640#" in the dialpad. It brings me to a screen that says. Debug screen and gives me 6 options but none of them allow me to follow the directions given here. It's running Android 4.4.4 btw. As anybody had success with a bad imei phone in general with this (or any other ) method?

If the phone gives you the MM06 code it is reported stolen, therefore it will no longer connect to any network carriers. You will have to have the IMEI cleaned. That is all I can say.
I have successfully unlocked the S4 on AT&T. I wrote a thread on it:

I have tried this but unfortunately i do not get the options on my n910t, i am trying to use it in Malaysia and it was brought from USA, anybody can suggest me anything please to get the sweet phone working again. thanx
There are a few caveats here. It doesn't matter if you have a sim card in or not when unlocking a phone via this method. You only need a sim from a different carrier to test it, although there is a GSM code you can enter on the phone pad to bring up the screen to enter an unlock code manually. You do not need that or even any sim card in the phone for this service menu method.
Simply
1) Enter *#197328640# on the phone dial pad
2) Select [1] UMTS
3) Select [1] Debug Screen
4) Select [8] Phone Control
5) Select [6] Network Lock> Options
6) Select [3] Perso SHA256 DFF.
7) Go back one menu "Network Lock"
8) Select [4] NW Lock NV Data INITIALLIZ
9) Wait a few seconds, depending on your phone reboot.
If you can't bring up the service menu on step 1 try to dial *#22745927 to enable hidden menu...press back...then dial *#197328640#
Another caveat is that this only works on certain firmwares. Im running Maximum Overdrive 7.1.1 and the debug service menu is empty. See attached screenshot. For example on the Note 2 the only firmware i could find with the correct service menu is the very first original firmware release android v4.1.1 T889UVALJ1:_(4.1.1) (11/02/12) I had no issue downgrading from v6.0.1 and back again. You can put a custom rom back on, or whatever you want after you unlock the device as the changes are made in the NV memory and it is unaffected even by wiping out any and all of your file systems. You will simply lose access to those sections of the service menu with most custom or newer roms you flash but you should be easily able to bounce around via Odin with ease on the Note 4 AND 2.

[HOWTO] / [GUIDE] SPH-L720 Domestic SIM Unlock T-Mobile:AT&T:metroPCS:Straighttalk
Streamlined Guide for Domestic T-Mobile GSM Unlock for SPH-L720
Credit for all of this goes to @autoprime and @nicotheandroidguy
A few notes: I used Windows 7 for the odin flashes , my phone is a SPH-L720 and it is not active on the Sprint network, also the sim card from t-mobile was inactive (brand new from t-mobile store.) and it has a bad esn. I am located in the Phoenix az market so I'm able to take advantage of the 1900mhz band that tmobile has here.
I'm unsure of how this will work with mnvos or other primary carriers and frankly I don't care at the moment, this is my primary phone. Update: confirmed hspa+ for tmobile, metroPCS, straight talk and AT&T.
I HAD MY NEW UNACTIVATED TMOBILE SIM CARD IN THIS ENTIRE TIME
1) First I reverted my rom to a stock MF9 rooted touchwiz rom, instructions and one click odin here:http://forum.xda-developers.com/showthread.php?t=2486134 I’m trying not to straight copy and paste someone else’s work so take a look at that post if you need a clean start. If you are coming from non stock you will need to boot into stock recovery and wipe data/cache before you get started. (I also later used SAC’s rom after a failed attempt at an AOKP fix and it worked as well ) you can switch to any ROM later and the unlock will stick.
2)I rebooted the phone and followed the instructions listed here in post #1 http://forum.xda-developers.com/showthread.php?t=2415587
3) I went to the dialer and typed *#0011# which brought me to the "service mode" Menu.
IF YOU HAVE TROUBLE GETTING THE HIDDEN MENU TO OPEN DO NOT FEAR! I had a ton of trouble at first. In some builds you need to activate an option by adding a line to your build.prop or changing the no flag in efs/hiddenmenu to ON. Google it, there is a ton of help out there.
4) Press the left menu softbutton (the menu button that lights up and vibrates when you touch it) then press the either the button “select” or “Key Input” and type the number 1 or 2 into the box, if nothing happens press menu and select the “back “ button then repeat. This app is sort of like a tin can radio, you can kind of tell that it’s working, but it doesn’t work well.
Depending on if you pressed 1 or 2 in the dialogue box it will take you into either an UMTS or CDMA menu. If you are in the umts menu, press the menu button and select back, this should then proceed to the next step.
5) Select CDMA, then 1.COMMON, press next page twice until you reach page three of COMMON and select 8.PREF MODE SET and select GSM_WCDMA_ONLY
6) Press menu and back until you are at the main menu and select [1]UMTS, then select [1]DEBUG SCREEN, then select [6]PHONE CONTROL, select [2]FAKE SECURITY CONTROL and make sure it is set to ON
7)Press menu and back and select [3] NAS CONTROL. We are going to check a few different settings in this menu so remember how to get here cause I don’t want to repeat myself.
[1] CIPHERING CONTROL = OFF
[2] INTEGRITY CONTROL =ON
[3] SIM CLASS CONTROL = UMTS
[4] REVISION CONTROL = DO NOT TOUCH
[5] RRC(HSPA) CONTROL = DO NOT TOUCH
[6] DUALMODE IMPROVEMENT CONTROL= DO NOT TOUCH
[7] NAS AVOID SECURITY CONTROL= OFF, 0
[8] BIP BLOCK = 1
8) Press menu and back twice, you should be on the PHONE CONTROL menu. Select [7] NETWORK CONTROL, select [1] GFC and make sure that it is set to [1]GSM/(E)GPRS/WCDMA REL8 .
9) Press menu and back and select [2] BAND SELECTION and select WCDMA/GSM ALL for both WCDMA and GSM band preferences. I selected the ALL choice for LTE as well even though I know it isn’t supported for TMOBILE.
10) Under the NETWORK CONTROL menu we just came from select [4] AQUISITION ORDER and change it to [3]UMTS_GSM
11) Press menu and back until you are in the PHONE CONTROL menu and select [5] SIMULATION , press the [2] SW WATCHDOG button 6(six) times and then the [3] HW WATCHDOG 6(six) times. Nothing will happen at all to let you know if you have done this correcctly but as soon as you finish the sixth press on HW WATCHDOG reboot the phone manually:manually:manually IMMEDIATELY . I’m not sure what this does or why this works but @nicotheandroidguy seems to have divined that this is the vital part of the process.
YOUR PHONE STILL WILL NOT HAVE DATA OR VOICE WHEN YOU REBOOT FROM THE WATCHDOG TAPS DO NOT PANIC!!!!!!!!!!! (hopefullly you have your towel with you)
12) WIFI that sonofa up and search for apn settings shortcut and build.prop editor in the Play Store.
Go into the build.prop editor and add the following two lines:
ril.sales_code=LOL
ro.csc.sales_code=LOL
REBOOT PHONE MANUALLY now.
Now Install and create a shortcut on the home screen and select to open. Press the menu soft key and select add apn.
Use:
Name: T-Mobile
APN: epc.tmobile.com or fast.t-mobile.com (for LTE devices)
Proxy:
Port:
Username:
Password:
Server:
MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
MMS proxy:
MMS port:
MMS protocol: WAP 2.0
MCC: 310
MNC: 260
Authentication type:
APN type: default,supl,admin,dun,mms
13) Go into your android settings, select wireless networks, you should see the network mode set as wcdma only do not change this, we set this in the Service Mode Menu , Check that your roaming settings are set to for roaming data/ international data etc.also make sure that there are no roaming guards left on. (roaming guards will only allow you to uncheck GSM and GSM data under international roaming.)
14) reboot
15) profit
At this point I had full access to the TMOBILE UMTS/HSPA+ network and voice/text/mms were working.
At this point you may change roms, be careful not to update past mf9 as you may be unable to downgrade to mdc. YOU MUST DOWNGRADE TO MDC MODEM FOR THIS TO WORK.
If you use a non touchwiz rom you can still access the tellinfo menu by pressing *#*#4636#*#* and selecting WCDMA only and manually adding the apn.
GOOD LUCK! let me know what needs changed in the guide as well.
If you have questions it's useful to know your Baseband /kernel/ rom.

My 1st newbie post:
Thanks for OP's excellent post!:good:
I have a Sprint Galaxy S4 is with stock MF9 (not unlocked).
I have spent days reading about how to get a rooted/unlocked MJA S4. But still could not find answer to the questions:
1. Will this also unlock international sim?
I guess yes, as domestic is harder to unlock. But want to hear the confirmation.
2. You mentioned you used MF9 rooted.
If I unlock it, then update to MJA, will that void the unlock?
3. Does this unlock works with MJA? If it works, do I need to unlock MJA first?
4. If I want a rooted & unlocked S4 with stock MJA, what is the simplest way and the correct order to achieve this goal?
Can I update to MJA, then root, then unlock?
Or do I need to root the MF9, then unlock, then update to MJA, then root?
If I update to MJA first, I can't go back to MF9, correct?
Thank you very much!

Ok
1)i am unsure of whether mja can be unlocked internationally or domestic . If you read the first direction it actually instructs you to downgrade to mdc modem. I'm pretty sure the reason has to do with the options available to you in the hidden menu.
2)i used mf9 rooted as a starting point to downgrade to mdc to perform the international unlock. Autoprime said in the thread that upgrading to mf9 would keep the u lock however I haven't successfully upgraded to mf9 and kept the domestic unlock. I'm going to try to get it to work today but not with mja until there is a reliable downgrade option.
3)i have no idea. I wouldn't suggest trying until there is a reliable downgrade option.
4)i would really slow down and read the international unlock guide from @autoprime I think it will answer a lot of your questions. Like I said I would wait to upgrade to mja if you want a for sure domestic Sim unlockunlock.
Thank you very much, imbmiller.
I will just wait patiently for the MJA solutions before upgrading to MJA/root/unlock.

So would this also work for AT&T sim? has anyone else tried? Btw, was thinking of updating to 4.3 and MJA but i guess i will have to hold off on that if i want sim unlock international or domestic? I am on MF9 with sim international unlock right now. Would I have to go down to MDC to get this to work?
Also, if you want to go back to sprint again, how would you do it?

Hi thanks so much for putting this together all in one place!
Hi I'm on MF9, rooted, locked.
So really the two major steps are:
1. Do int'l unlock first (autoprime)
2. Then do domestic unlock
My question - after you get both unlocks working and say you have your phone working on tmobile, what do you need to do to get it working on Sprint... rather, is the phone operatable on both Sprint and Tmobile? Or do you have to do some tinkering to get it back to working on Sprint again. I'd like to have the flexibility of popping SIMs in and out and switching carriers at will, Sprint included (b/c I don't want to cancel Sprint just yet...eventually, but not immediately). Thanks!

Another question
When you're tinkering with swapping out modems and APN settings, does doing a nandroid backup prior help so when you have an "oh sh!t" moment, you can just do a full restore...? Or is what's backed up in nandroid outside (excludes) these changes? Thanks.

OK the answer to the first question is to put your sprint sim card back in then put your phone back in to lte/cdma auto through the tell info app through Google play device info then change it in to lte/cdma auto.
Answer to the second question is that the nandroid might help you in a oh sh!t moment but the modem and settings for the unlock stay after a factory rest but a other update could kill it. A stock Odin flash and dailing ##72786# could also kill both unlocks.

Sorry I had to edit my post. It did work. There are two different GSM SIMs the one with the dot seemed to work. I Got Edge, 3G, and H+. It is awesome. I also still have 3G with Sprint with the SIM in. I got two phones in one. Thanks.
So I've been on T-Mobile for the last 24 hours but my HSPA+ signal is weak and slow (under 1mb), while my co-worker on T-Mobile (and a T-Mobile phone) has full HSPA+ signal and speed (5-9mb).
Any thoughts on what could be the cause?
I'm running CM11 on MDC. I'll try some other combinations tonight to see if things change.
Hi Guys,
Thanks for the help in advance. I just want to ask if anyone experience issues unlocking galaxy s3 mini gt-i1890L from telcel Mexico. When I put a different SIM and restarted thr phone. It only tells me "Network Lock". It doesn't show any fields to enter unlock codes. I factory reset in phone and kies as well as reload official samsung firmware and no luck.

You said you tried entering codes to initiate unlocking (how many codes do you have) if you enter the wrong code too many times your sim will be blocked and you wont be able to use it and will have to get a code from the sim provider to unblock it.

Hi there,
What I meant when I tried to initiate the unlocking sequence, I dialed these numbers and nothing works. The phone doesn't respond to any of it. I pressed the dial icon but it just says "Not registered to network". For some reason when I insert a different SIM Card and restart the phone. It comes up to a screen saying "Network Lock" and that's it. It doesn't even allow you to enter unlock codes. All you can press is "Dismiss" Like what I showed in the picture. I don't know how to enter the unlock codes anymore since the phone will not respond to any of these service menu codes but it does respond to *#197328640#.
Method #1 Insert a Non accepted SIM card in your phone and power on. Once finished loading your phone will ask you to enter a code, enter the Unlock Code
Note: Non Accepted Simcard is any simcard not from the original provider
OR
Method #2 Go to the dial screen on your phone as if you are going to make a call and press: #7465625*638*UNLOCKCODE# (8 digit unlock code)
OR
Method #3 Go to the dial screen on your phone as if you are going to make a call and press: #0111*UNLOCKCODE# (8 digit unlock code)
OR
Method #4 Go to the dial screen on your phone as if you are going to make a call and press #7465625*638*# Once prompted for code, enter the 8 digit Unlock Code.
I tried these service codes as well and no luck
*#7465625# = Check the locks.
*7465625*638*Code# = Enables Network lock.
#7465625*638*Code# = Disables Network lock.
*7465625*782*Code# = Enables Subset lock.
#7465625*782*Code# = Disables Subset lock.
*7465625*77*Code# = Enables SP lock.
#7465625*77*Code# = Disables SP lock.
*7465625*27*Code# = Enables CP lock.
#7465625*27*Code# = Disables CP lock.
*7465625*746*Code# = Enables SIM lock.
#7465625*746*Code# = Disables SIM lock.
Can you start the phone with a sim from the correct network?

Yes, I tried both. I have the original Telcel SIM card and other SIM cards. The phone just doesn't respond to any of the service codes to initiate unlocking. Only message I got was "Network LOCK" and a picture of a padlock and a button that says "DISMISS"

I am not entirely sure, but it is probably the same case as my Galaxy Ace a few years ago. Unfortunately, Telcel adds an additional lock layer that is embedded in the ROM, so any effort does no good. What I did to unlock it, was download another firmware from Sammobile that was compatible from another carrier. You may choose that path, or flashing a custom ROM. Obviously, this implies you must have root permissions enabled on your mobile device.

I have the exact same problem with the Galaxy S3 mini from Telcel. Even at professional unlocking businesses this was a problem.
Their is just no option to enter unlock codes, neither does it respond to "Method 1-4 unlock codes"
After entering *#197328640# in the keypad the options are
[1] Debug Screen
[2] Version information
[3] common
After selecting [1] debug screen, there are 8 options
[1] BASIC INFORMATION
[2] MM INFORMATION
[3] RR INFORMATION
[4] NEIGHBOR CELL
[5] GPRS INFORMATION
[6] SIM INFORMATION
[7] HANDOVER
[8] PHONE CONTROL
Phone control has 7 options
[1] DRX CONTROL
[2] FAKE SERIAL CONTROL
[3] NAS CONTROL
[4] UE STATE CONTROL
[5] SIMULATION
[6] NETWORK LOCK
[7] NETWORK CONTROL
and network lock says Not Active.
I bought a cheap $20 phone make and receive calls but if their is away to unlock this thing that would be greatly appreciated.
I would rather avoid installing customs ROMS however i can root and unroot with VROOT. So if there is some .apk that needs to be modified or something that would be a better option. If anyone can help with this issue, it would be greatly appreciated. Thanks..

I also got this info at a code unlocking site.
*Note regarding Samsung Android phones:
If your phone is locked to Telcel or Claro Mexico or Claro
Worldwide, before placing your order please try inserting
a non-accepted sim card into your phone and ensure you
receive a prompt to enter the unlock code.
If you do not, you may need to either root your phone or
change to the latest North American firmware prior to
placing an order as you will not be able to enter an
unlock code until the firmware is updated.
The phone originally came with jellybean 4.1 but was updated to 4.1.2. Dont know if that has anything to do with it
hi after hours of trying to make my phone work with GSM Sim (T-Mobile), i successfully managed to make it work and here are all the steps I did so other people who can't make it hopefully will see this guide atleast somewhat helpful
here is what i did:
1) first of all, i s-off my HTC One (H-boot 1.55, 3.05.651.6)
-here is the guide i followed
-the same guide but in video
2) flashed the Sprint_HTC_One_m7wls_1.29.651.10_RUU.zip (to downgrade to 4.1.2)
-it is the solution 3), a) here
3) Unlock and root the phone
-a very good guide
note: to make the developer option appear under settings you NEED to go to Settings > About > Software Information > More > and TAP the build number about 7 TIMES, after that the Developer options would appear on settings.
4)The sim unlock guide here
5)Then the GSM Fix connection drop here
-I followed the guide made by xerxes1987 because it is free
exact steps i did:
a) put the phone in CDMA preferred (see step 4 for ref)
b) Dial ##3424# and make sure you tap on and tap the SELECT (VERY IMPORTANT!!!)
c) go to device manager and manually install the driver for HTC DIAG 9k ONLY(you dont want to mess with the one without the 9k) can be found here note: DO NOT download the 9K (COM105) as it is an adware program
d) download, extract and run CdmaDevTermV.2 then scan for ports > select HTC Diag 9k > connect. Under SPC/Lock on the drop down arrow select HTC and scan (you need to copy that number generated). after that select disconnect and close program
e) download and install QPST. run the QPST config. Under ports make sure you select and enable the HTC diag. then under Start Clients select service programming and select your phone and press OK. scroll to the right till you find 1x/HDR Security. Under R-UIM Config drop down selection, select R-UIM only then write to phone (it would ask for SPC number, just put the number you copied on step d and press ok and make sure you let the green bar finish otherwise you RISK bricking your phone)
f) do step 4 again to set it to WCDMA preferred
g) pop in a gsm sim if you haven't already (I tested mine with T-mobile). It would say no service at first but don't worry. go to Settings > Mobile data > Network mode > and select GSM/UMTS Only. then go back and select Available GSM networks > select the first option (cant remember what its called and it would take about 3-5min.) Then select your carrier (in my case T-mobile) and it would say registering something and after that I have the signal bars and it works now with my T-mobile
since I did not made the steps, all credits to where its due.

I have a dumb question.
If I SIM unlock will I be able to utilize my local carrier's gsm data network. They said they won't be able to, but I believe with the right settings/hacks it can be done.
Another thing to add, my locK. Arrier has JUST one phone that utilizes its 4g Ltd and that is the LG as840, is there a way to modify the phone to use it?
The data is slow as pooh over cdma, I believe my phone is in evdo mode or what ever. I would like to perhaps switch carrier's for faster data.
Great guide I will try when I access the pc I put my adb stuff on.
Another question.
Do I have to stay on 4.1.2? Or can I just flash a nandroid and move forward with it?

Hi, I have finished all step up to step g. When I select available GSM network-> search for available network, the phone doesn't show up anything. Any advice? What can I do? I'm sure I have T-mobile signal here since I have been using T-mobile
Thanks for this guide. Its really helping me inch my way closer. I heard however that I need to flash an earlier sprint htc one radio in order to connect to domestic gsm networks... Is this true? I have done so and can not pick up any signal whatsoever. i have completed all the steps as well.

keep doing the available gsm search until T mobile appears.
I did mine about 4 times before it appeared.
Hi raclimja,
In my phone when I go to Settings > Mobile data > Network mode, it gives me only 2 options (LTE/CDMA and CDMA Only) there is no GSM option. So my question is about if I will follow this whole guide, will I see GSM options in Network Mode then? I have HTC Desire 816 (virgin mobile) CDMA phone and I want to unlock in to my GSM carrier looks like a great guide with a success rate .
Please reply. Thank you.
I flashed older radio after that unlock was complete I'm on lollipop
Unlock your Samsung Galaxy Note 4 for Free to use with any carrier of your choice by using the following secret trick:
1. Insert the foreign SIM card into your Samsung Galaxy Note 4.
2. Turn your handset off and back on again.
3. On the dialpad on your phone, type in *#197328640#.
4. Then select [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3] Perso SHA256 OFF.
5. Wait for 30 seconds or so before returning to your main menu by choosing back.
6. In the main menu, you should see a “Network Lock” message, now choose [4] NW Lock NV Data INITIALLIZ.
Not working on SM-N910F, tried *#197328640# and nothing happens?
Looks very much like what I did to unlock my S3 quite some time ago, it worked but only on Android 4.1 if I remember right, anything above that and an option was missing from the hidden menu so you either had to roll back or use another method.
Can anyone confirm this works (I would try but I don't have an alternative SIM)?
Not working here either. European SM-N910F

That used to work in early versions of firmware on Galaxy S 3 and Note 2. Samsung closed that loophole in firmware updates at least in US

I don't have a foreign SIM but tried it with another UK SIM. Would that make a difference?

the difference its because the secret menus appear only whit a foreign sim card

Shouldn't make any difference, I think the point is to prompt the SIM unlock code box.
I used a 3mobile sim in an EE locked 910F and that sequence of numbers brings up no such menu, I'm pretty darn sure this doesn't work on any variant because as pointed out above.... Samsung locked this out ages ago, in fact it was a surprise you could do it then!
However, I'm all up for being proven wrong, proof please.
So I just found this to get into the service menu - http://forum.xda-developers.com/note-4/general/enable-servicemenu-galaxy-note-4-hd-t2919157
If anyone can find a sim unlock method via that then brilliant but I doubt it!
OP got this from Drippler They say this MAY or MAY NOT work

Looks like a copy and paste from the S3 and Note 2 Thread. It's exactly how I unlocked my old S3 but it only worked on android 4.1.1 and was locked out in the next update.
This does not work on our Note 4.
I don't see the same menu

Please read the past few posts. This doesn't nor has it ever worked on a note 4. No need to revive a dead thread.
