Network locked requiring master unlock code - Galaxy S6 Q&A, Help & Troubleshooting

I had to call Samsung
oopsies said:
Ok, I figured it out. This is how I did it in case someone else encounters the same problem in the future:
1) wipe cache
2) factory reset phone
3) after setup, immediately put in the non-Bell network SIM card. Then enter the network unlock code. Reminder, if you are in Canada, CRTC requires all carriers to give you the unlock code for free even if you're not a customer.
Now you can go and root your phone, etc. I hope this helps someone!

I tried your way but it did not work for me. the issue got solved after I called Samsung because of two different code need to be entered simultaneously more than once.

[Q] unlocking with code?

Hope somebody can help. I got rid of at&t service and they gave me an unlock code if I wanted to get service from t-mobile. I am going to use the phone just for mp3, gps, etc..., but I won't use any phone or data features. I'm not sure if I should unlock it and I don't know how. I'm also wondering if anyone has developed a rom that eliminates all of the phone features? Any help would be much appreciated.
Looks like my post is one that got messed up while the server went down. Somebody had already responded and said they doubted there was a rom that would have the phone and data options stripped out of it. So the only question I have now is how do I unlock my phone with the code at&t gave me? I've searched the wiki and it just points to sites that are trying to sell unlock codes. I have the code I just don't know how to use it.
To apply the unlock code, you first need to insert another carrier Sim card into your device. ex: T-Mobile
1) Shut off you device
2) Remove your battery cover
3) Remove your battery
4) Slide in a non at&t Sim card
5) Pop in your battery
6) Re-apply the battery cover
7) Power on your device
8) Once your device boots up, you'll be prompted with a "Your device is Sim Locked" type of message
9) From there, you should have an option to Unlock your device with your code
10) Taa-daa!
** You can use a friends Sim card to unlock, as long as it's not at&t. Once unlocked, just give them back their Sim card.
Thanks for the info. It's very much appreciated.

[Q] Samsung Focus Unlock Code (ATT)

not sure if this belongs in this board, but Ive been calling ATT for a while now to get an unlock code for my overseas trip.
I got mine, but...
I just don't know how exactly I'm supposed to enter it, Ive been getting mixed messages from each rep involving the steps, but the code seems to be the same.
Can someone tell me how to enter it?
---things they've told me:
- you need a diff carrier's sim card
- you dont need a diff carriers sim card
- you need to enter stuff like (#7563*638*.........)
- you dont need to enter stuff like (#7563*638*.........)
Well I just called ATT and was given my unlock code... The directions given weren't the best but managed to get it unlocked to hopefully I can help.
The woman on the phone gave me a long winded code #746...*638*742.....# Which obviously didn't work since there is no option to type in # or * when getting to the unlock screen. So I just started typing in the different numbers she gave me. I typed in the second series of 742... numbers which was 8 digits in total and hit enter and my phone was unlocked. I should also mention I did have an Australia sim card in when doing this so I'm not sure whether or not another sim is needed in the process.
Hope this helps and you can get it to work...
what is the 742 number sequence they gave you? id like to try it with my unlock code.
I actually left the code I was give at work so can't give it to you ATM... From what I've read all each individual phone has its own unique code so its doubtful mine would work anyway.
Basically what I did is entered the last 8 numbers that ATT gave me with my Aussie sim in the phone. If you're still not able to get it to work tomorrow I'll find my code at work and you can see if it'd randomly work for you.
I still haven't been able to unlock mine.
Could you please give me a step-by-step guide for unlocking my phone the way that you did?
I just need the steps and the 742 number, i already have my code.
Thank you.
Found this (and cleaned it a bit):
How to enter the unlock code for Samsung Focus (aka NCK)?
To enter unlock code for most Samsung:
Method 1:
1. Insert a foreign sim card
2. Enter the PIN if the card has it
3. now enter code NCK
=> the phone should be unlocked
If your phone does not ask for an unlock code:
Method 2:
1. Switch ON your phone with a non accepted SIM Card
2. Compose:
#7465625*638*CODE#
OR
*#7465625*638*CODE#
OR
#0111*CODE#
WARNING: entering wrong code 3 times or more will FREEZE the phone and you will need an UNFREEZE code (another one).
Hope one of above works for you.
Samsung Focus Unlock worked..
Thanks to Zehns10, the instructions worked perfect. Not only the AT&T person spent an hour trying to help me without success, but I also spent an hour with Samsung Technical Support Level 3 guys and it was a total waste of time.
The key to unlocking your Samsung Focus phone is to have a "NON AT&T SIM CARD" with you and insert that in your phone to proceed with unlocking. Both AT&T and Samsung Tech support will tell you to take the SIM card off and try all kinds of stuff and it simply won't work.
Happy camper, I am now!

Yep, my phones unlocked now
Thanks.

Agreed - this is what I had to do to unlock my phone - AT&T rep was useless.
Thanks!

I've asked AT&T (just in case) via email and they send me an unlock code with complete instructions including that step (non-AT&T sim card). Total time spent - less than 5 minutes (except waiting for reply, of course). So if you not in hurry, use email
what is the procedure?
i got the unlock code from AT&T
but no procedure.
when I power on I get SIM ERROR
so...where do I enter this lovely code?
AT&T instructions (my copy&paste):
1. Power off the device and insert a non ATT SIM card.
2. Power on the handset.
3. Network Lock will display enter the device unlock code.
4. The SOS key (Left Soft Key) on the lower left side of the device keypad will change to OK. Select OK.
5. Display should read Network Lock Deactivated.
PLEASE NOTE: You only have five (5) tries to unlock the phone. If this process is unsuccessful five times in a row, the phone will be permanently locked to the AT&T network.

Sir, I have got my unlock code. When i enter a non accepted SIM card i am getting an error "Incorrect SIM". It does not ask for unlock code. I want to try Method 2 mentioned by you but i am not quite sure what "Compose" means as mentioned in step 2. Also a few screenshots or a video tutorial demonstrating method 2 will be a great help.
Thanks in advance.
Where can I get the unlock code?

Ask your provider (T-Mobile).
question?
can I ask a really dumb question:
below Method 1 says "3. now enter code NCK" .... Where? using what? the widget that pops up asking for the Pin is a numeric keypad only.
what is it that allows the 'input' of "NCK"???
and similarly, in Method 2, what device/widget/applet allows the input of "CODE" ??
i guess others know this, but so-called "legacy" SIM's are not liked by the i917

I live in Egypt and I won a Samsung Focus S in a Windows Phone development competition (it was held by Microsoft Egypt).
The only problem is that it's locked by AT&T and I'm unable to use my Vodafone Egypt SIM.
I contacted Microsoft here but they keep telling me that they'll get me the code and they don't, so I decided to do this myself.
Can you tell me how to contact AT&T to get the unlock code? I don't think I can call them because that would cost me A LOT (international calls here are very expensive), and tell me what I need to say to them in order for them to give me the code
Contact AT&T via email (see my posts above) or just pay $20 to these guys: http://www.samsungimeiunlock.com/samsung-focus-s-unlock (I hope, $20 is not A LOT for you? )
Ok so I just discovered that I can call AT&T's customer service from Skype for free
So I called them and I told them about my case and gave them my IMEI number, but they couldn't find my unlock code
I asked them what could be the reason for that, they told me that with new phones like mine, the manufacturer doesn't release the unlock codes to the carriers until some time has passed, that time can be a month or a year or forever!
Can someone tell me why would Samsung do this? and does that mean I'll have to use samsungimeiunlock.com to SIM Unlock my phone?
20$ isn't that much (it's approximately 120 Egyptian pounds), but I would've preferred if I was able to get it for free

XDA Q&A isn't the best place to ask rhetorical questions. Forward your question to Samsung. Also, as for samsungimeiunlock.com better to ask samsungimeiunlock.com guys directly (I'm not working on samsungimeiunlock.com).

[Q] Unlocking sim card Hell

Hi there!
I just bought a SE Xperia x8. It was Locked to 3 uk.
I used a unlock online service to unlock it. Did everything right as it was in the unlocking manual. But in the end of the process the software Multi unlocking client frozed. The know the mobile doessn't recognize any sim card.
In the hiden menu the X on the network lock is not there anymore as it was unlocked.
And when I try to connect to a network the message I get is "Your sim card does not allow a connection to this network"
I rooted it changed roms and the problem persists
Can anyone help me?
The Online unlocking service wants me to by more credits and try again....
Have the same problem... any fix for this?
I just opened my own thread for exactly the same thing last night - did either of you have any luck getting this fixed?
Oh God, I remember MultiUnlocker from my Palm Pre days. What a horrid piece of software it is.
I'd recommend contacting their support division and outlining your problem. I was able to gain the necessary three credits to unlock my phone (stupid bloody thing took that many goes).
It may prove problematic that your phone is kinda 'in limbo' ie. showing unlocked but not. You should be able to input a code from the emergency dialler giving you access to the engineering menu, which will allow you to re-lock your phone, then the code should work.
I'll subscribe to the thread in case you need further advice!

Unlocking Z3 T-Mobile USA

I have the Z3 from Tmo usa. I also have the unlock code i paid for. when I insert foreign sim, it does not prompt for unlock code, instead directing me to use the unlocking app on the phone provided by tmobile. How can I get this thing to ask for the code.
So far i have figured out it is missing the Simlockunlockapp.apk from priv-apps
this is the app that asks for the code.
Have u found any way to unlock the xperia z3 with the unlock code?
Boom. Finally worked this morning for me.
I'm getting it force crashing on me. Is there another app it requires? I might have accidentally blocked/disabled?

Was your phone active for more than 45 days on T-Mobile?
How did you unlock it, please provide more info.
What info was it asking for, to get the device unlocked?
Was your device with BAD or Clear IMEI?
Thanks in advance!
1. Yes
2. Used the unlock app. Interestingly, after the permanent unlock, the app deletes itself (at least the icon)
3. None, it verifies your eligibility with T-Mobile servers
4. Clear IMEI, valid account, paid full price for the phone
Is there anyone who tried flashing a rom via Recovery to get the unlock code menu to pop up and insert the code?
i am stuck with the network lock. unable to unlock. anyone pls shed some light on this.. its dark for very long time..

Stuck in setup phase after factory reset of latest Android P beta

So after the latest beta install I noticed a few things acting oddly so I opted to factory reset my phone to see if that helped. The reset went perfectly well but during the setup process of activating the phone/linking to your gmail account I got stuck at this carrier code portion. It is asking me to either enter a carrier code manually or scan a QR code. I have contacted Google Fi and they have no idea what this code means/believe there are no such codes.
I tried using Tool All In One to reset my phone to an old image but it needs me to have an unlocked bootloader which I am having a hard time finding how to unlock while stuck in the setup phase/in recovery mode.
Any help with this would be greatly appreciated.
Edit: When I press "Don't have a QR code?" it just goes back to that exact same screen.
Any luck?
I have the same problem. I opted out of Android Beta, and after the phone restarted, I went through the same process you described. I contacted Google, they couldn't help. They transferred me to the Fi team, they couldn't help and within a few minutes they offered to send me a new phone. They don't usually do that, so I suspect they are aware of more than they are letting on.

Have you tried a different SIM or taking it out altogether?
I had the issue too I'm a Fi user and I just skipped setting up my project Fi Esim and just setup over WiFi then used the Project Fi app to set up my service
Resolution
Hey what's up everyone, so.... I've been running into this issue as well because I factory reset my phone after google assistant glitched out on me day in and day out by constantly crashing. Yes I have project fi, yes I use esim instead of a physical sim card. Yes I have tried the skip method. IT ALL BROUGHT ME BACK TO THE SAME SCREEN.
I am currently studying network operations and security and have been racking my brain about this issue.
**** WHEN IT ASKS FOR QR CODE SCAN OR ENTER MANUALLY, HIT ENTER MANUALLY**** ENTER YOUR IMEI # Located on the box your phone came with, or it's also allegedly found where your sim card goes in on the pixel., This helped me get past this screen of QR code and helped me get off google support chat for 3 hours.
Of course after you get past the QR screen I also found myself without cell data, so I went into my project Fi App and from there I was able to activate service.
TRY IT, and if it worked, I love you too.
