No credit to me, . Was just browsing the international forums and came across this:

Apparently it works for ATT folks, tried it on my rogers phone it didnt work. If it worked for anyone here please let me know. Also please thank the original threader if it worked.
EDIT: I think this works on rogers too. I forgot to INPUT THE * before the # , i didnt see that. ahaha.! Wow it cant be this easy!
2nd edit: confirmed working on rogers, telus, atnt, mobilicity, telus, bell
I just did it, will try and put in a different sim when I have a chance.
1- Before the procedure I installed an old inactive T-Mobile SIM card and was asked for an unlock code after the lock screen.
2- I powered down the phone, reinstalled my active AT&T SIM card and did all the steps mentioned in the other thread. First time I din't see one of the screens (the one prior to hitting back) so I did it a second time and all was according to the instructions.
3- I rebooted with the AT&T SIM card and then I shut the phone down again.
4- Inserted the same old inactive T-Mobile SIM card used on first test and I wasn't required to enter any code like it did before!
I cannot test any further because I don't have access to any other active SIM Card!
Lets wait and see if it was really that easy to unlock :highfive:
Did the steps on my Bell phone and put in a telus sim and it worked.
badass, worked on mine! (didn't check to see if it was already unlocked, though...)
This is really GREAT NEWS ...
Have anyone tried to see if it still works after the FACTORY RESET.
Worked for me. On Rogers

Did this last night, but I don't have another SIM card to try. Will test it out when i get to work.
edit... I can confirm that it did work on my AT&T i317.
Confirmed working for telus sgh-i317m.
Thanks! You deserve some credit coz I barely go through the international version thread and I would have never found this method if you didn't post it here. Of course the other guy gets a Thanks and a beer from me but you get a click on your Thanks button for reps!
I did it a couple of days ago. Tried it with my O2 pay-as-you-go SIM from the UK. The GN2 got a signal and connected to the network, so it does work. In the past, I got the screen asking for the unlock code.
Can someone try this link and tell me if it says unlocked?

Worked for me
I tried this on an AT&T Note 2 (SGH-I317) and it worked for me. I put a T-Mobile sim in it and it did not ask for an unlock code. Thank you guys!!!

That link seems to only check iPhones. I think the more important piece is that the phone accepts and works with non-AT&T SIMs. That pretty much means it's unlocked.

that's amazing it works for everyone !
Yep. Worked for my on my SGH-i317. I stuck in an inacitve Verizon SIM and no promoting for unlock.
So one thing I noticed is Settings -> About -> Status ... At the very bottom it says: Device Status: Modified. I never noticed this before ... Did that just appear? My phone is bone stock and has never been rooted or modified other than the unlock procedure.
Can someone else look at this before and after? I may go to the ATT store and unlock a display model to test...

Rooted an AT&T phone. It was unlocked previously and had a T-Mobile SIM and was working great. Rooted to get hotspot. After rooting T-Mobile SIM working as well as hotspot, however, when I put in AT&T SIM phone says "No SIM card"!
AT&T Card will work ok in my iPhone.
Any ideas would be appreciated.

Thank you for the tip. Discovered the SIM tray was deformed and not seating the AT&T SIM.

Was gonna say... Root can't cause that. Lol.
Is there any way to get wifi calling on att with an unlocked s9 from best buy? Flashing att firmware or would it be best to get the att model? Must have wifi calling for work reasons and I hate all the bloatware but might not have a choice.
at&t probably blocks it, if you don't get their version. I have an unlocked, but on T-Mobile, and it works.
I flashed the AT&T firmware on my unlocked S9 and wifi calling and video calling worked.
With the stock firmware on the unlocked S9 nether option was there
Can you point me in the direction of a download for the stock firmware for AT&T? I'm wanting to do the same as well, but feeling pretty clueless about where to obtain it. thanks!
Same here. It works for me on T-Mobile
If I flash the att firmware will I still get firmware updates?

if you flash the att firmware or buy it straight from att you will end up a device supporting the same capabilities. So it's down to your tech skills or budget.
Where can I find the latest att firmware? I did not see it on sammobile.
How to
Step 1 Go to this thread for Firmware (thanks @iBowToAndroid)
You will want to go to the link for the U firmware and find the folder with the AT&T userdata file (RB7) download the user data file and the full firmware.
Step 2 Go to this thread to get the modified version of Odin that recognizes the GS9 firmware files. (Thanks @mweinbach and Raymondf )
You will then flash the downloaded files from Step 1 in Odin, after flashing the firmware the phone will boot into recovery and you will need to wipe data and cache.
Thanks so much... that did actually help me... as a fairly tech savvy person who doesn't really get into this stuff much, the lingo I didn't know was leading me astray... I had come across that thread but didn't recognize it as anything that would help me. Thanks again! Onward to bricking my phone!

Thanks for the info. A follow-up question: is it possible to flash it back to the stock unlocked firmware? The reason is that I'll need to use foreign SIM card when I travel overseas.

I have unlocked version on TMobile and wifi calling works just fine.
Do you have to flash the att firmware to the unlocked version in order to get VoLTE? I don’t care about WiFi calling, just hd calling and being able to stay on lte when making a call, rather than have it drop to HSPA during the call.

Probably wont last. Unless att has an imei number from an wifi calling att phone on that account it will eventually go away.

I understand, but unless att has changed its policies in the last month, if u do not have an imei number on that account that is an att phone with wifi calling it will turn itself off as soon as your phone is interrogated by the network. Theres 100 threads on it , applies to unlocked s8, s7, etc...
Toggle is there because of firmware, not because it works.

Any help/guidance for me??
I have tried a few times to use the March 2018 RB7 files with the ATT user data to get my phone to ATT stock - primarily for the Enhanced LTE (data and voice at the same time), as well as Wifi Calling. I can't get that version to load. I did get a more recent version to load (RK1) - and maybe that is the issue. Just wondering if there is a newer set of files and what specifically I should use (AP,BL... UserData) to get the phone fully set to AT&T. I now have the wifi calling option, just can't get it enabled. Any help is appreciated.

When you try to enable it do any of the AT&T Wifi calling configuration screens pop up?
I flashed att firmware on an unlocked note 10 plus but att still sees it as an unlocked phone. Is it possible to change the phone to completey read as an attvbranded model? I called to see if they could provision the IMEI of my phone and they were able to tell right away it was not one of theirs, even though it was running att firmware.

No, because (as you found out) the IMEI number is not from an AT&T branded phone.

I have a GOOGLE unlocked phone. I flashed N975U firmware on my phone and also flashed ATT USER DATA at the same time.. When my phone booted up - it had all of the ATT BLOAT that comes on an Att phone - it booted up with the ATT LOGO - it shows ATT ICONS in the Status Bar for Data (5GE instead of showing LTE or 4G) and I have Wifi Calling and Video Calling working on my phone...
https://androidfilehost.com/?w=files&flid=301224
That is all it took. I didn't have to call ATT - It all just worked - and it was not working that way BEFORE I flased Userdata.
YMMV but I have heard about others who had the same experience. Go tot he N975U Firmware thread and find the download for ATT USERDATA - That is where I found it....
Hope that helps you.....
Pixel and iPhones are supposedly able to do those things. I think that may be why it worked for you

Wish it was possible, but unfortunately no way exists.
If you have WiFi Callling, Video Calling and Volte working, why does it matter if ATT recognizes your phone as one of theirs or not? Just curious about what you are trying to accomplish ?
I was looking at a sprint phone that i want to use with at&t and wanted to know if that would work
No. Locked is locked. Changing firmware does not do a carrier unlock.

Nope, the only way ive found is via paid services. I unlocked 3 of them for $10 each. Cannot discuss further on XDA tho
