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.

Try this
#7465625*638*# (Insert Network Lock Keycode)

I've already tried that, the phone doesn't respond to this keystroke sequence.

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!

[Q] SIM unlocking phone

Hi all
I recently came to the end of my contract, and decided that I was quite happy with my Desire HD, I would switch to PAYG
So I got a code from Orange to unlock the handset.
I put my new SIM in, and it came up with "SIM Network Unlock PIN" and a text input box, plus buttons for Unlock and Dismiss.
I enter my unlock code, and it says "Network unlock successful"
As I understand it, at this point it should reboot and reflash the radio. It does not do this, it simply goes to the home screen and I have no reception. It is just as if I have clicked Dismiss.
Please can someone advise how I can get this to work?
I'm running IceColdSandwich.
Thanks.

Did you put the sim cover back on? Its needed for the antenna

Yes, I did. As I said, it hasn't even done the bit where it reboots to flash the radio.

What if you reboot manually? You could always head back to the carrier and let them know the code didn't work.
You could also achieve soff,in doing so also sum unlocks

If I reboot manually it just boots as normal and shows the "SIM Network Unlock PIN" screen again.
I think the problem is the handset rather than the code, as when I enter the code it does say that it has been accepted - it just then doesn't reboot.
Thanks, I'll try the SOFF method.

I can't get ADB to connect from my work PC, so I'll try this when I get home later.
Thanks.

S3 does not want to unlock, tried different methods

I just repaired the screen on this Galaxy that was giving to me, its a i747 ATnT S3. I want to unlock it so I can use it on TMobil
So I went on ebay and I ordered an unlock code, 5 bucks is no big deal, does not work. Instructions says
Method one
1. Insert Unauthorized Sim Card into device
2. Power on the device
3. Enter Unlock Code when prompted
4. Device should be unlock if "Code Accepted"
Error I get is that the code is wrong. I tripled checked it, it is correct.
Method 2
1. Turn ON your phone Authorized Sim Card
2. Type #7465625*638*CODE# (CODE is the Unlock Code I sent you)
3. Device should say "Network Lock Deactivated"
4. The phone may reboot and the unlock is completed
I get an error "connection problem or imvalid MMI code"
There is more here http://ebay.unlockfusion.net/#help
I tried with and without a sim card and it does not work. The sim card I used from ATnT does not have DATA but I can make calls. I also tried using my TMobil. Nothing works. Can anyone help me?
I called him ATnT, I asked for an unlock code, they gave one to me, BUT, the one they gave me is the same one I got from Ebay, and they said to insert a none atnt sim card, when it asks you for unlock code, you enter it, and thats it. But I get an error
"Network unlock request unsuccessful"
Why am I getting this error code?

Are you on a custom ROM? If so, you may wanna jump back over to TouchWiz for the unlock...

This is so frustrating I paid 220 to get this repaired and I can't even use it.
Before I was on stock, now I am using touchwiz, which I got from this Dev Thread, http://forum.xda-developers.com/showthread.php?t=2033132
I inserted a valid ATnT sim card courtesy of my mother. I Can make calls, use the web, and so on. So I should be able to unlock it using this method
1. Turn ON your phone Authorized Sim Card
2. Type #7465625*638*CODE# (CODE is the Unlock Code I sent you)
3. Device should say "Network Lock Deactivated"
4. The phone may reboot and the unlock is completed
The error I get, "Connection problem or invalid MMI code"
Why am I getting this error?
I also tried inserting an unauthorized sim card, my tmobil sim card, when it ask me for an unlock code, when I enter the unlock code, I get this error
"Network unlock request unsuccessful"
Do I have a phone that is just not unlockable? This is very frustrating... Any help would greatly be apprecaited

Can't Unlock from Rogers: Invalid MMI

I'm trying to unlock my Rogers SGS3, so I can pick up a paygo card while down in the U.S later this month. I purchased and received my unlock code through CellUnlocker.net yesterday.
However, no matter what I do I can't get any of the dial codes they give to work. They all result in "Connection problem or invalid MMI code." errors.
I've tried reverting to a backup of my rooted Rogers stock ROM, as other threads I've seen suggest that dial codes don't work on AOSP-based ROMs, but the results are still the same. *#06# works to retrieve my IMEI (worked under Jellybam 3.3.0 as well), and *#0011# works to bring up the Service Mode menu.
However, all the codes given by CellUnlocker.net in their email don't:
Different phones have different Unlock Code Input Instructions, Try the following Instructions in Order:
Method #1 Insert a Non accepted simcard 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
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)
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)
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.
If Phone says, "Code Accepted" or "Network Unlock Successful" or "Not Yet Personalized" your phone is fully Unlocked
--------------------------------------------
How do I know my Phone's Network is Fully Unlocked?
Go to the dial screen on your phone, and press *#7465625#
A menu will be displayed that will resemble the following...
1. [ ] Network lock
2. [ ] Subset lock
3. [ ] SP lock
If everything if OFF, then your phone is fully unlocked.

I haven't yet tried inserting a non-Rogers SIM card, because I don't know anyone with a phone that uses micro-SIMs. I'm also a bit wary to go and spend $20 on a Roam Mobility SIM card if I'm not going to be able to get it to work.
Any idea what might be the issue?
To verify that I am indeed running a stock ROM (as I restored from a backup I had labelled "Stock"):
Android version: 4.1.1
Baseband version: I747MVLDLK4
Kernel version: 3.0.31-538866
Build number: JRO03L.I747MVLDLK4

I believe you can't unlock without a different sim card.
Sent from my SGH-I747 using xda app-developers app

Yeah. You're gonna need another SIM. Stop by a T-Mobile store & ask them politely. They will probably let you use one.
Sent from my Galaxy S3

Thanks for the comments. I went and picked up a Roam Mobility SIM card at lunch, and putting it in I was prompted to enter my unlock code.
All seems to be working now.

Just search around here there is a free way to unlock your phone. Lots of people have done it successfully

N910P - I have MSL code but no prompt to unlock? please help

Hi All,
Please help.
Goal:
- unlock N910P for domestic US (I have MSL code from Sprint)
- do not want to root
Details:
- account and phone is paid
- Sprint gave me MSL saying it is my unlock code
- 5.1.1
- has been reset to factory and cleared cache
- I watched a few videos saying that I need to put a different carrier sim in and it will prompt for the MSL code to unlock
- I have tired 4 sim from T-Mobile and AT&T, 2 are working sim from working phone... none will prompt for code
- I tried ##3282# which get me to manual settings but I am not sure if I should mess with it
- invalid sim for T-Mobile and AT&T but works fine for Sprint
- I read that it may work with Kit Kat but I cannot downgrade without root
Thank you all in advance.
Please let us not get into the debate of carriers and GSM/CDMA. I just need help with the unlock portion. Thank you again. :highfive:

You couldnt downgrade to kitkat even if you were rooted. Youre on a locked bootloader.

yup, I concluded that after a few hours of testing... tried several rev of Odin3 and several OEM ROM... all fail to auth... was hoping as last option that root will work but didn't plan for that route...
Are there any options to get the prompt for domestic SIM/carrier unlock? Whether auto or manually?
The only paid unlock service I see for N910P that guarantee it is on eBay... are those trustworthy?

I'm sure there's some way to use your msl to unlock, but I don't know how.
But if you give up, I used www.idoneapps.com
I used him and worked flawless. They have good support too.
I think you need to flash pc1 firmware or below to unlock but after you unlock you can flash anything else. As long as you don't disturb your efs partition you'll be unlocked. (But this requires root)
Hope you figure it out without having to pay, but if not, they're great.

Here , this will take all your problems away ?

Unless ... for some weird aşş reason it doesn't work with your phone ? Then just look up on Google a secret dial code to force the network unlock code input for whatever phone you have
