Unlock Bell SGS

I have been unable to unlock my Bell SGS. Here's the history...upgraded to the Froyo version that made the location KOR (forget which version this was) but did the fix that removed the unlock PIN and SIM pin issue. Then I downgraded to the original Bell software and is now upgraded to the most recent Bell software via Kies. On the surface, looks like IMEI on phone matches the box, no real trace of the KOR (used a HEX editor on that nv file and it already said BMC) but tried to put a Fido sim card in, use the unlock code from varies methods and even tried the master code from Bell...nothing, won't unlock for any other carrier!! HELP!!!
Thanks

I had this same issue on my 1st galaxy s. I just returned it and the replacement unlocked with no issues.
One thing I didn't try was inputting the unfreeze code first. Might be worth a shot.
Put in the other providers sim card. When the unlock window comes up, enter the unfreeze code, then the unlock code and see how it goes.....

[Q] Repeated "network unlock request unsuccessful" message even after unlocking

[Q] Repeated "network unlock request unsuccessful" message even after unlocking
[Note, I do not have root (it caused too many weird glitches and I missed OTA updates).]
I have the Samsung Galaxy Nexus GSM originally locked to O2 UK. Months ago they provided me an unlock code and unfreeze code. When I entered it, the phone unlocked. But often, when changing SIM cards, I'd need to enter the code again. No big deal.
A few months ago it took several reboots and inserting the original SIM before the phone would unlock, but randomly it did.
Now I am stuck overseas, and have been trying for 2 days to unlock this piece of ****. The exact same code will not work. The unfreeze code will not work. I even just paid $25 to an unlock website, and the just sent me the same codes, so the codes are definitely right.
I have tried all of the unlocking instructions in their email. Nothing is working.
None of these instructions work. No network unlock screen appears. I believe this feature does not work with this phone:
Code:
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.
When I insert a non-compatible SIM card, it asks me for the unlock code, then says "Network unlock request unsuccessful". If I try the unfreeze code, it gives the same message. Then I try the network unlock code again and it gives the same message again.
I have tried everything in the email they sent me, but nothing works.
I refuse to format my phone for this! I have so many settings that would be lost.
Is there anything you can do to help me get this working, or explain to me the correct digits to dial in the dialer to get the mysterious "network unlock screen" to appear? I repeat, the digits above such as #7465625*638*UNLOCKCODE# do not work.

leave me a pm message, include your google id in it, and your model number (eg sgh-t654, gt-b5310 etc)

Thanks. May I ask why?

thought i could help you unlock it directly without need for unlock code, but just found out it needs more than just a usb cable. I am helping out other guys via remote usb connection.
In your case, I cant really help coz ur phone is new on the playground so it needs sophisticated methods to direct unlock it.

Foreign SIM doesn't prompt for unlock code -- how to unlock?

I have a SaskTel Samsung Galaxy S3 (SGH-I747M, baseband version I747MVLLE8) that is locked, and I want to unlock it. But when I insert a foreign SIM (from AT&T) I get no prompt for an unlock code. Instead it just says "No SIM card. Emergency calls only." I've contacted several of the online unlock code suppliers and they say without this prompt I can't unlock the phone. I've also tried to enter variations of the *7465625* code, but they do nothing at all. SaskTel says they don't provide unlock code. This despite the fact that I purchased the phone outright, and have no contract with them. Am I totally hooped, or is there some way I can get this phone unlocked?

try another SIM, maybe the one you're using is borked.

Possible, but I doubt it, since it works just fine in another phone. In any case I don't have another one to try.

Misread

#7465625*638*UNLOCKCODE#
I noticed in an earlier post, the place of the unlock code was after the #, it should be before. On the right track though. Probably just a typo.
unless you already tried that.

That and probably every variation of it I can think of! I am wondering though, is this code internal only to the phone, or does it go to the cellular network? When I do type it, it does nothing, though if I send it I get an "Invalid USSD" message returned from the network.

this code doesn't work on the LTE variants of the SGS3. most of the multi-stage codes (####*###) don't work, you just end up with an error.

Correct as stated. Additionally, if you have a foreign micro sim, and you are not on a stock ROM, the unlock screen prompt will not show. I was running AOKP, and could not get the prompt to show, so I flashed back to stock, unlocked phone, then flashed back to AOKP, bc TW sucks!

This is what I was starting to suspect. Can you refer me to a good, really clear step by step procedure to do this? I've never done this with a phone, and since I live in a small town, I doubt I can find anyone to help me here. So a step by step would be nice. Thanks.

are you on a stock ROM?

i have a i747M and unlocked it with the at&t micro sim, so i know it works,
did u cut ur at&t sim down to size ? maybe u did it wrong and it wont recognize, or ur sim slot is ****ed up ....
ur best bet right now is to try another micro sim

Ok, I've now got my phone rooted. Can someone suggest how I can get the ROM set so that it will allow me to enter the unlock code when I insert a foreign SIM.

There's a 3rd potential method that hasn't been mentioned on here that we see working for most Samsung handsets. In fact, for some Samsung handsets (usually older ones) it is the only unlocking method that will work.
It is:
1. Turn on the phone with a non accepted or accepted SIM card inserted
2. Type #0111*CODE# replacing CODE with your network unlock code
However, if your service provider lock is active, then you'll need to use the code #0133*CODE# instead.
All unlocking methods (once you have the unlock code) are available here: http://www.mobileunlocked.co.uk/samsung-instructions.asp
Hope that helps.

Did you manage to unlock?
I'm facing the exact same issue. My S3 doesn't show the network unlock prompt when I insert a foreign SIM. Mine is locked to AT&T. It's also SGH-I747 model

You could try and unlock your phone as per this thread:
http://forum.xda-developers.com/showthread.php?t=2033225
Then try the SIM card after the phone is unlocked.
Oh, I believe this only works on Stock ROMS.

Follow the link Tybalt quoted, you will unlock your phone and the sim won't ask for an unlock code because well, it's unlocked.... Follow the instructions, you need to be on JB 4.11 for this to work, some have had success on custom roms but not many....you don't need to root to do this and make sure when you see the success code you have 40 at the end not 30... i did this a couple times... 30 I think basically means you have locked it again ... and in the instructions when it says wait 30 or 60 seconds... you really do have to wait.. don't be impatient....it's a huge thread with many many successes.....

Samsung Galaxy S3
I have the same issue but I have a sgh-i747 Samsung galaxy S3 i brought it to koodo and was told it was a compatible phone with the company when unlocked. The problem/question i have is When i insert my new simcard the screen will not display any prompt to input a unlock code. It just says emergency calls only or unregistered sim. I inserted my sim card into another s3 same model, software versions, different provider, and the phone asked for the unlock code right when powered on. So i tried and flashed a new firmware but its doing the same thing.
I called koodo and they gave me instructions to create a new apn of Koodo SP it did not make my phone prompt me for an unlock code.
When i send an email to any website about unlocking my phone they advice me not to purchase there product if my phones not prompting me for a unlock code that will it more then likely not work.
I've seen methods online of using these to input an unlock code "#0111*UNLOCKCODE#" or "#7465625*638*UNLOCKCODE#" but when i tell the unlock website this information this still tell me not to purchase there product and i mean many numerous websites. I do not want to buy an unlock code only to try to input it with these methods and have it not work. Which i highly dought it would because the normal 7465625 command doesnt work either.
I also tried this factory unlock and it did nothing
PLEASE HELP!?!?

Thank you so much for this!
Whenever I typed any variation of the #7465625 code I would get the "emergency calls only" message. #0111*CODE# did the trick!
The provider didn't even know this, the best they could come up with after numerous calls to their hotline is that the phone was broken and/or that the SIM card was badly inserted, thus I should mail them the phone to the other side of the country for unlocking. Would they even have known how to do it over there?
My grandma says thanks!

Need help unlocking

I need to unlock my wife's S3 and I got the unlock code from AT&T but when I try to do it, it says unsuccessful. The phone is completely stock not even rooted. Can anyone help cause AT&T is useless?

Does the imei match the imei on the phone's printed label?

Yes it does

When you insert a non-ATT sim, you get the prompt to enter the unlock code? If you do and you enter the code provided by ATT based on the phone's imei, sounds like ATT may have given you the wrong code.

Yes then it gives me and sim unlock unsuccessful. I am getting sick and tired of sitting on hold with them

I'm not sure if the s3 gives you a limited number of tries to unlock it but I would not attempt more than 2 attempts each day.
I assume you confirmed the imei # with ATT? Is it possible the phone is hard-locked to ATT? Did ATT give you any other codes such as unfreeze codes, PUKs, etc.?

i know you said stock , unrooted. dont you have to be on 4.1.1 to unlock? prob. are, just asking.
err on the side of kindness

What ROM is on your phone? If it is 4.1.1 or 4.1.2, you could try using the free unlock method.

I'm having the same problem here. Received a code from AT&T on Oct 26th and they're still trying to figure out why it doesn't work. Bought the locked phone at BestBuy and never touched it until I tried to use the code they gave me.

If you were on 4.1.1 or 4.1.2 and the code didn't work, you could revert back to stock 4.1.1 and unlock the phone for free. Since you're on 4.3, you can only unlock the phone with an unlock code. Seems strange that the unlock code doesn't work. Did you confirm you phone imei and the imei you submitted to ATT?

Yes, I checked everything. Today I spent almost an hour on the phone with them trying to figure out the problem. They even called Samsung and they didn't know what was wrong either.

Is it possible that the phone has become hard-locked to ATT due to too many unsuccessful unlocking attempts?

I read that the phone displays a message when that happens, and none has been presented so far... It always asks me for the network unlock code.

Problem solved
To whoever is going through the same trouble. This is not the "unlock it for free" method, for you will need to insert the unlock code
For Samsung Galaxy S3, S4 and Note 2. Device must be updated to the latest firmware.
Phone MUST prompt for the code. This is the "release method" on the phone(s).
a. Go to the Dial pad and dial *#197328640#
b. Click on number [1] UMTS > [1] Debugging screen > [8] Phone Control > [6] NETWORK LOCK
c. You will see 3 options. Click on number [1] Perso Sha256 INFO, the screen will change slightly
e. Hit the MENU button then when the menu pops up carefully hit BACK to return to the previous screen
f. 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
END

Unlock issues with DN4 rom 4.4.4 with att unlock code

So I have managed to unlock it with the unlock code from att.
I used this access number to get into service mode
*#0011#
back
input key Q
back
input key 0000
and just wait
it will bring you into the service mode.
So I have a att note 2 running DN4 rom 4.4.4.
I requested a unlock code from att. Tried to enter unlock code ,unlock unsuccessful message appears .
Tried some steps I found online but still nothing.
When I dial *#197328640# it says connection problem invalid mmi code.
any thoughts?
I'm using an active t-mobile card to unlock device.

Most of the time, when having problems unlocking, you need to go back to stock rom of the device. Then if the problem still exists, you most likely have the wrong unlock code.
