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

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.

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?

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...

No I mean while doing this process? Odin thing.. does it matter which SIM I have to keep in note
This http://galaxynote2root.com/galaxy-note-2-tutorials/how-to-unlock-sim-for-free-on-gsm-galaxy-note-2/ is the tute I believe, gotta remember it's been 2 months since I did this, so I'm not quite 100% certain. LoL
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:
Hi all,
I would like to start off by saying that i dont care about any warranty or any such issues. I had bought a S4 in US which i brought to India without ever activating on T Mobile network. This means that on contacting T Mobile, they are unable to send me any activation code which could SIM Unlock my device.
So now my only problem is to make my device usable. I see two options:
a) SIM Unlock
b) Complete removal of firmware and install some custom ROM, bootloader and other components to get rid of T mobile network
Problem is that i am a newbie and couldnt find any thread that could help me. MY device is updated to the latest version i.e. i am on 4.4.2 with baseband as M919UVUF9B4 and knox bootloader
Can someone help me out. I have already tried rooting the device and trying some apps which suggested that would help me unlock my device but none of them worked..
Thanks

If you paid T-Mobile the full price for the phone approx US$500-US$600 (not the subsidized price) before you left, they should provide you with the SIM Unlock code. You may need to talk with another customer service agent. However, if you only paid the subsidized price, then you've broken the contract with them, and they won't. You'll have to contact a company that will sell you an unlock code.
As to rooting the phone, have you tried this one: http://forum.xda-developers.com/showthread.php?t=2294005 ?
If this doesn't work, you're doing it wrong.

Flashing a custom rom will not allow it to work on a different network. The phone will still be sim locked.
Like the post above me says, call T Mobile and have them give you the code. If you didn't pay the phone off, they won't give it to you nor should they.
Chainfire's Region Lockaway app will SIM unlock in the process of removing region restrictions. I remember reading something to that effect anyway.
For use chainfire's Region Unlock, you must be root.

Has any one had positive experiences with SIM unlocking the AT&T sgh-i747 (Galaxy S III) after the 4.3 update with a code??
I paid $14.99 to SamMobile to unlock using their software but it didn't work and they don't answer my emails. But that's not with a code
Admins: if there is a thread for this already, please point me to it. I could not find one with successes after the 4.3 update
Note that AT&T didn't want to give me a code: I had cancelled the service already and paid the ETF (foolish, I know), and now they don't care about me
I've seen plenty if users have success unlocking with a code. I don't know about how sammobile does it though.
You have to be stock for it to work BTW.
Sent from my SAMSUNG-SGH-T999 using Tapatalk
Thanks doc. By "stock" you mean the official ROM without root? As I said, it's not the original version (4.1.1) but the OTA update to 4.1.3 by AT&T
I will have to buy some code
Root doesn't matter. Many custom stock based ROMs will also work but some may have removed some needed files which is why I just said stock. As long as its stock based and has the stock dialer it should work though.

Official AT&T Unlock Code Fails
My contract ended id-September so I requested an unlock code, which was previded (below). I sent two separate requests for the unlock code and the number provided twice matches. I tried the unlock code (while using a T-Mobile SIM card) twice and the phone said the code was incorrect.
I prepared the phone by doing a factory reset. These are the phone details:
Model number
Samsung-SGH-I747 running
Android version
4.4.2
baseband
I747UCUFNE4

These are the instructions provided:by AT&T:
Thank you for contacting AT&T Customer Care about unlocking your AT&T Mobile device. We have reviewed your request and confirmed that the device may be unlocked. You should complete the unlock process before porting out your number for use with another carrier. Please allow 24 hours upon receipt of this notification to complete the unlock process.
Your Unlock Code is :12345678
Unlock Steps - Use Non-AT&T SIM Card
1. Power off the device and insert a non-AT&T SIM card.
2. Power on the device.
3. Network Lock displays: Enter the device unlock code.
4. Enter the eight-digit unlock code.
5. Press OK.
Note: You are allowed five attempts to unlock before your device permanently locks to the AT&T network. Note: If your device has been altered from the original manufacturer's standards, such as rooting the device, your unlock code may not work and you will need to contact the original manufacturer for assistance.
For questions regarding AT&T Mobile device, please visit the Phone/Device Learning Center. Thank you for your business. For other questions about our AT&T wireless service or other Mobile devices, please visit att.com.
I've tried the unlock twice and it did not work. The phone is rooted. I think I manually installed 4.4.2 because the OTA failed many time to update.
I think these instructions are confusing in that step 3 and step 4 both say enter the unlock code. Is there a second code? I thought an phone unlock code is a single 8-digit number.
I have successfully unlocked an old HTC Aria so I have a little bit of experience performing unlocks. But if you have advice I'd appreciate hearing your thought.

Forgive me for asking but is your phone running a stock ATT ROM? Does the imei obtain from the phone match the imei on the label under the battery?

Yes, the IMIE shown on the label and via About device --> Status are identical. I asked AT&T twice for the unlock code because I thought maybe I sent the wrong code. I'm 99.9% sure the IMIE number I used is correct.
Yes, the flavor of Android installed is the AT&T version. If I recall, in August 2014 I used ODIN to manually install 4.4.2 because the over-the-air update was not working. (The OTA would download but fail to install. I'd wait for two or three days before I could try a second, third, forth... time.) I have also done a reset via Accounts --> Backup and reset. The MicroSD card was erased too, through the reset process. The lock screen, the home screen, all the typical AT&T add-on applications seem to be as they were when I purchased/upgraded the phone two years ago.
4.4.2 is rooted and I have Chainfire's SuperSU v2.00 Pro installed.
I should mention this: When I look at About device --> Status, all the way at the bottom, is "Device status" which shows "Custom". This isn't a setting. I suppose this is why the network unlock code is not working.
I'm not sure what to do next. I can't recall the page on XDA which guided me through the install of 4.4.2. I'll look a little harder because I'm sure I used XDA as my guide for the upgrade. Perhaps I'll try to install a non-root 4.4.2 image.
I never expected that I'd have five and only five tries at network unlock. I've used three tries... I need to make sure the last two work! Any advice is appreciated.
Sorry, I'm out of ideas. All I can suggest is flashing back to completely stock with stock recovery and no root access.

In my case AT&T told me they would not give me a code until I paid off my contract. I would seem they don't care about their former or current customers.
I showed them though, I was still on 4.1.2 and simply donwgraded my modem and used the free unlock method. It's now time to upgrade to kitkat.
@wpscully
Don't know if you still need help, but maybe this would do the trick? I think it's the last post that's describing a different method of getting the unlock code to work.

@DocHoliday77, your pointer you mention above has proven invaluable. For the record here is the link I used; http://forum.xda-developers.com/showpost.php?p=55677344&postcount=137 MrBrown72 has a secret code and menu selections which seem to tell my phone to ignore all the customizations I made (root, maybe removing some AT&T bloat) and accept the valid network unlock code AT&T provided when my contract ended. The phone is now working on T-Mobile, rooted still, and none the worse for wear. I also want to thank Audit13 for advice on what not to do, and well as his guiding me so I found the hints that the phone considered itself "custom".
Finally I'll mention that if I had not been able to unlock this phone I never, ever would have selected AT&T as a cell provider. In this process they were professional, respectful, and helpful. T-Mobile didn't get my old line transferred before my AT&T contract ended. AT&T probably could have made clearing up this transfer very hard. But they were kind, understanding and efficient in reinstating my old number briefly so T-Mobile could finish the transfer.
I know others have had trouble with vendors. I wish all companies could understand that being unhelpul or rude is the fastest way to lose a customer for life.
would just want to know by any chance if flashing another rom pr rooting the device will remove the network lock of my carrier?
Thank you
I need a method to unlock the device, tried a lot of paid services already,most of them dont have an unlock code yet for my device and some sent me a wrong unlock code

The most reliable unlocking company would be the carrier itself

Hi
I made a stupid mistake with my G988B, its were not working well, so I decided install a stock rom, but downloaded and installed o last version of software from another country (G988BXXS2ATD5, XEF ) whit Security Level Patch of may 1, 20.
After installed new stock rom, my phone ask for Network Unlock Code.
When realized of my mistake, tried reinstall orignal version of firmware (G988BXXU1ATCT, PGU) but nothing work for me. I have tried to flash with Odin, but always, process stop in "flashing vbmeta.img."
I have read a lot tread trying figure out my problem like: https://forum.xda-developers.com/galaxy-s20/how-to/howto-root-s20-series-upgrade-firmware-t4079353/post82220417#post82220417
There is a way to come back original stock rom and then trying unlock network?
Could this process work in my case without damaging my phone?
Thanks.
Samkey can unlock phone with 1 or 2 credits

Thanks por your answer, but I did it.
It doesnt work.
Samkey is the only way to unlock a Samsung phone other than getting the network unlock code from the network or third party. You must know what you are doing. Google the process. If that doesn't work then there is an issue here that needs further investigation. Also ensure your active csc code is the one that was originally on the phone as well as stock rom. Sam key can be used to change csc as well.
Good luck

Thanks mikey_sk,
My problem is that both the csc code and the stock rom are not the original ones. Therefore I am looking for a guide to help me how to get back to the stock rom.
I have read that the problem is, the security patch that I installed as it is newer than the one I am trying to reinstall. I will keep trying.
I understand that so far there is no way to go back from binary 2 to binary 1.
Any help is appreciated.

Ok,
Thanks.
No more questions.
You can always use the sim slot 2, it is usually not locked.
I suggest you change the csc to a stock one using Sam key. Make sure you enable USB debugging in developer settings otherwise Sam key won't work. After that dowload the most recent stock rom for that device from sammobile and flash in ODIN but DO NOT use HOME_CSC so it can do a full wipe and rebuild the firmware. As an added measure as soon as installed go into recovery and do a full wipe. If network is still locked try unlocking it with samkey

Unfortunately for it, you mentioned only sim1 is blocked and you still can use sim2.
This is not network lock but rather imei blacklist.
The only way to fix this is to pay your telco bills from where you purchased the phone. If it's a used phone, I would get a refund. There is no roms you can use that can fix it as it's blacklisted from the telcos.
There is only 2 reasons it is locked.
1. You didn't pay your installment bills.
2. The phone is reported as stolen.
If you purchased a used phone, get a refund.
