Hello,
I just retired my venerable Samsung T699 Relay 4G (RIP QWERTY Keyboard) and, just picked up an unlocked, "refurbished" AT&T Note 3 for pretty cheap (it was sold as an "International" model, so I didn't know it was an AT&T version until I got it). I've had T-Mobile service for the last couple of years, and the big draw, for me, is WiFi calling/SMS; I've installed SafeStrap and been trying some T-Mobile ROMs, but can't seem to get WiFi calling to work. Obviously I've got a T-Mobile SIM card, and I've tried changing/adding APNs, and installing different builds of KitKat (some of which won't even boot - NB4 and NF9 seem to work best), but I still can't get it to work properly. I've been racking my brain and searching the Interspace for the last two weeks with no luck... what am I missing? Is it even possible?
Thanks in advance!
Hello,
As a fellow N900A user on Tmobile, I have been trying to get wifi calling as well.
I tried using a tmobile stock rom with wifi calling baked in (tweaked), but that did not work. I was told that I need to add an emergency 911 address, but even doing this did not do it.
I would think that wifi calling is doable, but something tells me that tmobile might be doing something similar to Verizon. Rumor was that Verizon had a list of IMEIs, and if your IMEI was not on their list, you couldn't bring the phone over to Verizon, even if it were CDMA capable (once again, this is rumor as I cannot confirm this is true).
The closest I have been to getting wifi calling through tmobile was having the settings show on the stock tmobile rom, but that was about it. Maybe someone in the forums has an answer/got it working, but I have yet to see one. I'll keep you posted if I somehow get it to work, but something tells me this won't happen for a while.

Yeah, considering I have zero service with any provider where I live (but 4G LTE 100 yards down the street), WiFi services were the single reason I went with T-Mobile. Considering the Unlocking Bill, one wouldn't think a carrier could block IMEIs from being used on another carrier... but I have a hard time reading the fine print, so there is that.
I've tried several of the stock T-Mobile ROMs, and while WiFi calling was there, it simply wouldn't enable; it would try to enable, but never would. Have you contacted T-Mobile and asked if there are any potential fixes? I'm considering doing that, but am worried that they'll say "Oh, that's your IMEI, looks like you can't use it on our network SORRYABOUTYOURLUCK!"
I have contacted tmobile about this before.
Their response was that they did not know why it did not work. They helped me set up the emergency 911 address, but they said when it comes to other hardware they couldn't give me a reason why it wouldn't work.
I remember dwetherill (sp?) mention that some n900a users were able to get wifi calling on their phones. I don't know if the modem can/will affect wifi calling, but at this point it's the easier thing to test.
I'm on the NJ5 modem - I might try testing out NC2.
Have you tried carl's TMB version of the norma stable rom? Check it out if you haven't. Wifi calling is supposed to connect automatically. I haven't seen it work yet, but I'll keep you posted if somehow I get it to work.

I'm on NC2, and haven't gotten anything to work as of yet... I've been looking for modem threads, but I guess I need to look a little harder. I'll search that ROM out and give it a shot, and let you know if it works with NC2. Thanks for the heads-up! :good:
So I tried NC2 modem, and it is not allowing for wifi calling.
I went to tmobile yesterday to get another line added. Rumor on the tmobile side is that AT&T is working to get wifi calling setup for the n900a's by around April. Take it as a rumor at this point, seeing how it came from tmobile, but the rep made a good point - AT&T tends to follow what tmobile is doing, so who knows.
Here's to hoping they're right.
BTW, I went to the note 4 tmobile forums, and I grabbed a deodexed stock rom. I noticed that there were a few files related to wifi calling (had WFC in the name). I tried playing around with it last night, and I managed to get the settings. It will even go so far as to turn the phone GSM radio off when you select wifi only. It's doing what Tweaked was doing for me (which was keeping the wifi calling option grayed out (enabling). I think I'm still missing a few files to get it to work, but I'll keep playing around with it later and let you know if I have any success.

I wonder how that would work regarding using a T-Mobile SIM in the AT&T phone, and if it could support cross-carrier features like that.
You're a braver soul than I, that's for sure. If I knew anything about what I was looking at/for, I'd be more than willing to help get this nut cracked... otherwise, I look forward to your findings!

Didn't have any issues with mine out of the box or now that I've finally got all the T-Mobile stuff working with it's CSC and apps. I've called out and received calls in both circumstances and had zero issues. What provider are you with here?

How did you get the tmobile csc? I was having call issues too but when i changed the ims settings and enabled volte calls got better but when im in a area with bad lte service calls are taking long to go thru. Could that be a csc issue? Also i dont see a link that the op is saying you provided that fixed the problem

Extracted it from the T-mobile ROM and dropped the files into a CSC changer flashable zip for an S8, modified it so it would work on my Note 8 and flashed it.

i spent 45 mns on t mobile call then i realized why i'm calling them since my phone isn't a t mobile one lol
i flashed Kalm file
and that fixed my issue
hopefully the main dev can port it over
i don't think he's gonna be too happy with his file being modified like that

Not Odin, it is a flashable zip so you'll need a custom recovery and probably root

Ended up calling t mobile and they had me reset my network settings then turn off my phone while they did something on their end. Turned my phone back on and boom no more problems. Didn't want to try root yet until there was a more stable one available. Thanks for all the help

yeah it's in my thread here https://forum.xda-developers.com/showpost.php?p=73858645&postcount=17
But I redid it last night after someone confirmed that they didn't even need the Note 8 CSC files, and I deleted out everything for other carriers so the new file is only about 120mb instead of 300-something.
I can post that up after work if you want to wait, uploading is blocked here at work for some reason.
Have to add that wifi calling still doesn't seem to be working, but VoLTE does since calling does not drop me from LTE. I have no menu settings for either still, but after doing a full reset, reflashing etc I have the wifi calling quick toggle but it doesn't seem to turn on all the way - the "on" color is light-grey instead of white like everything else (dark grey when off) and in the System UI tuner app, no icon is set for Wifi Calling or VoLTE.

Yeah it's in my Exynos T-mobile CSC thread but I've got a better smaller one now. I took a pack that @TEKHD made for the S8+ F variant and switched out the files with Note 8 T-mobile files but there is a little bit left to go to make WiFi Calling work on our N950N, VoLTE works, HD voice works, video calling works, but I'm still trying to figure out what's missing for WiFi calling. It's menu isn't even showing up yet.
Current flashable zip is only 88mb and I'm fairly sure whenever I figure out the remaining files that need to be copied over it won't be much larger.

I'm about to do a factory Odin flash to stock and test the latest version - if it works properly I'll post it up with a link - though I don't want to step on anyone's toes since the core script and idea belongs to TEKHD.
Fair warning as far as right now I still haven't figured out why WiFi Calling is missing, I set up this the same way he has his S8+ pack for their F variant aside from adding a few framework files that I found referenced in the Tmo Wifi Calling apk that don't exist on a factory Korean N950N but are on the Tmo ROM, and my theory if this next attempt doesn't enable WiFi Calling is that the N950N is fundamentally either just missing more files that need to be in place for it to work and I haven't found them yet, or that it has different/incompatible versions of some files that the T-Mobile Wifi Calling needs to function.
In other words I have 2 more things to test, then I am going to try fully wiping, flashing an N950F-based ROM and apply the T-Mobile WFC pack to that, since the S8/S8+ options that enable it for those folks are for the F variants, not the N variant but the F and N have the same hardware.

Sounds good. I went through the same things with my Note 2 years ago. I figured it out and got WiFi Calling working.
Fwiw, I have no interest in Wifi Calling on my Note 8, as my signal (also T-Mobile) is always good, and I use Hangouts (or whatever) when I'm on Wifi, for free calling.
I don't have Note 8 yet, but will order soon from the same seller as you.
Do you have any other suggestions for getting everything up and running for T-Mobile (except WiFi Calling), or is simply flashing the CSC file?

If you don't care about Wifi Calling yeah I would say just root, custom kernel, and flash the CSC. You'll get VoLTE, HD voice, video calling etc

I just got my new unlocked S10 all set up dialed in. Model SMG973U1ZBAX.
I put in my AT&T SIM card in and went to turn on Wifi calling and couldn't find it. I've since learned that if you have an unlocked phone, you can USE the AT&T network, but you can't get Wifi calling (which is a must for me), Visual Voicemail or HD Voice.
Instead of flat out returning it, can I just flash the AT&T ROM and it would be as if it was a a stock AT&T phone?
I know I would get all the bloatware and stuff like that, But I have to have wifi calling.
Are there links yet to Stock AT&T ROM for the S10? I couldn't find any on the site.
Thanks

Yes you can there's a thread somewhere in here with specifics on how to do it. I know you have to flash thru patched Odin and make sure you also flash userdata and csc to corresponding carrier.

Root is unrelated to firmware flashing. You only need Odin and the fw package. Your computer may, or may not need the Samsung USB drivers to be recognized.
Samfirm can be used to pull updates. You might find it on sammobile or updato, haven't checked.

Sigh. Well. I can report and confirm that you can not use Wifi calling on the AT&T network with an unlocked S10.
Even though I loaded stock AT&T firmware, and was up to date, it just won't work. Gotta return the phone.
I've been dealing with their advanced tech team for over a week and they said that because the IMEI number shows it's an unlocked phone, the system keeps denying Wifi calling.
We actually got it to work at one point. It was a 3 day process with one of their techs forcing my IMEI number through their system. It worked for about an hour, then their system caught it and kicked out it's provisioning.

Galaxy S10 unlocked ATT firmware question
Hi I recently got Galaxy S10 Unlocked phone on online. At first i didnt get ATT wifi calling options appeared in my phone. Later i followed same thread that has 973U ATT firmware links, and flashed using ODIN. I can see all ATT apps and ATT wifi calling option now but i cannot enable it. When i enable it i got a message saying we cannot turn on WIFI calling on this a device and error code EDS0008. I tried to call ATT folks, but they are saying WIFI calling and HD voice is not supported on this unlocked device. Somehow they are seeing 973U1 as model number, but i had 973U as model number. I tried chaining sim to old iphone and I saw WIFI calling is working with IPHONE, but its just this phone I am seeing error. I am not sure what to do now. Did you see this issue ?
Can you give me exactly about the files you used and post steps to get att wifi calling ?
sorry for posting questions in multiple threads
I have an unlocked S10e and I use T-Mobile and before even flashing T-Mo firmware, I did have WiFi calling out of the box. Change carrier

Your best bet is to do an exchange for an AT&T version.
You can Flash the AT&T firmware. But there will be no way in h*** for you to actually enable the Wi-Fi calling feature since they block those IMEI numbers on their servers. YOU HAVE BEEN WARNED. YOU MIGHT NOT BE ABLE TO REVERT IT BACK TO THE OTHER FIRMWARE.

Yes, that post and a couple others. Pretty painless process TBH.
I can confirm Wifi calling works, HD voice and a WAY WAY WAY better signal. Prior to flashing to ATT I could barely use my phone on my subway ride home... Now it works very well the entire trip.

I can confirm Wifi calling works, HD voice and a WAY WAY WAY better signal. Prior to flashing to ATT I could barely use my phone on my subway ride home... Now it works very well the entire trip.

I successfully flashed and am now seeing the ATT bloatware but WIFI calling and visual voicemail, etc are saying "OOPS! We can't turn onWi-Fi calling for your account. I'm going to attempt to flash with the clean boot version and see if that changes anything. Did you do anything different or additional to get it up and running. Not sure if it matters but I'm in Southern CA.
Has anyone else been successful in adding wifi calling, hd voice, etc?
I'm using build G973U SF6 with USERDATA_ATT_G973USQU2ASF6.
I'm on a US Unlocked Galaxy 10.

I'm away from the computer I did it on but I used the SAT1 firmware file and then manually updated all the way back up to the June update.
The updating part is/was a major PITA as it wiped the device each time. I'm hoping i'll get OTA's when they are released. Time will tell.
I'm in the Bay Area on ATT and it activated right away on the base february firmware I installed initially. Also I don't think I did any userdata stuff as I don't remember choosing it... I'll update this post tonight when I can check all the files I d/loaded on my machine at home.
Couple other things:
I can't find it right now but I followed a post that stated to make sure the SIM and SD card were removed during the flashing process. Not sure if that makes a difference.

did you ever run the unlocked firmware on ATT or did you flash to att before ever using an active sim? i had heard some speculation that once you run an unlocked phone, then it gets registered as "non att"... keep in mind this is 3rd hand info and hearsay.
edit. i guess i failed to read you short post... i see "prior to flashing" spelled out for me right there....

Any chance you found those other posts you mentioned above? I continue to be unable to get wifi calling on my phone.
By the way for anyone else, while I did not get wifi calling, visual voicemail, etc. I do see an improvement on my cell reception over the ATT network.
Ops sorry, thought I replied.

I followed those steps exactly.
Hi guys. My goal is to be able to use my AT&T phone/service as a 'hotspot' again, which I have been able to do with my Note 8, but can't get it to work on my Note 9 now. I'm familiar with the technical stuff (thanks to you guys over the years), but need to have an idea of what will solve my problem. Facts first, then what I think might be the issue...
I've been using a Note 8, which I bought overseas, here in the States with my AT&T account which does NOT have the hotspot feature included. It just works though. I put in my SIM and it all boots up fine (with no ATT branding during boot) and my Note 8 has a hotspot feature, which I turn on and it works just like it's supposed to. No issues at all.
Now, I have an unlocked T-Mobile Note 9 that I want to use instead of the Note 8 I bought overseas. When I put ANY US carrier SIM in it, it forces a reboot, and when it boots up it shows whichever carrier's SIM I put in it. If I put a Verizon SIM in it, it reboots and starts showing the Verizon logo during boot, and the same with ATT, etc.
I don't mind that, HOWEVER, now when I try to use the hotspot feature, I get a warning saying something like 'your plan doesn't have the hotspot feature. Please go to to our website to choose a plan that does' and the hotspot feature is blocked completely.
Is it blocked on this unlocked T-Mobile Note 9 because it installs any SIM's bootloader each time or something? I am assuming that allows/forces the carriers to install all their own stuff each time I put a new SIM card in it, which would allow them to also block the hotspot feature on my ATT account, since it's not included in my plan.
If this is the case, is there a way to 'fix' this? I know it's unlocked because it works with other carriers, but I'm thinking maybe the bootloader is locked or something, and if I'm able to unlock it I could put a new OEM flash on it, and maybe it would work just like my unlocked Note 8 that I bought overseas which allows the hotspot feature.
Please advise, if you have any ideas for me. (Unlocked T-Mobile Note 9 SM-N960U)
I would hazzard a guess AT&T is blocking you. I have mobile hotspot in my plan and it works fine on my note9.
You need to flash the u1 firmware for hotspot to work.
Thanks for the help. I'll update this later if it still doesn't work after flashing.

youll need the patched version of Odin to flash cross carrier firmware. Not a biggie, just know that regular Odin will fail. Not might, will.
So many people are reporting with the 3/1 sweep by AT&T, that they are blocking almost all Unlocked phones: See: Downdector Link We personally have a S10 (G973U1). AT&T is saying on this list: AT&T approved phone list that it is supposed to work. But like many other people "calls" end immediately, but we can text and data work. It is some sorta ploy by AT&T to force us to upgrade our phones. They want us all to upgrade to S22s. Anyway I was ranting. Anyway, if you look at that link, they are saying that the phone has to be on the latest software. The last update from AT&T or the manufacturer was in January. I checked the firmware site, and Android 11 is the latest in January. I'm wondering if there is some hack to get us on to '12' or something. An update might solve this issue. We know that a new SIM does not work. Calls seem to be rejected on the network, just based on the phone model or Android version.
We are aware that a version 12 is out there for the phone, just that firmware is not for our US-unlocked model yet. But maybe it can be hacked?
Edit: It appears this thread may be linked with this older one... But it is ever more pressing issue now:
S10 Unlocked phone with AT&T Firmware here they explain how, and the problems with flashing. This was back in 2019, so I'm not sure if this will still work. Even then it didn't work for everyone. Some in that forum claimed that it did. AT&T seems to now be blocking from their calling network any phones not enabled with VOLTE and the extended AT&T services that are not present in Unlocked phones.

I was helped by a user to achieve ascendance onto the AT&T network. I'm not sure if I'm to reveal his name. We 1) go into Developers mode on the phone. 2) Hack the Kernel. 3) Flash the rom to the G973U (model)... with the AT&T firmware. So that the Wifi-Calling and 5G features would work, and AT&T would allow it on their network.

I've literally been searching for an answer to this for days now. My wife and I have S10's. I work far from home so I really need her phone working in case of emergency. Can you please point me in the general direction? Thanks!
Agreed, I didn't know such a thing was possible, but I'd love to hear more about this!

At first I had to use the Samsung Band Selector app from the Play store and go into More Network Settings > AT&T > Preferred Network Type and choose 3G. Unfortunately this killed LTE so all data and calls were going through H+. As I was mostly on wifi I could live with it since I could actually use the phone again.
Then Friday morning I checked for updates and there was the update to take me to Android 12. I took the update then when it finished it said it needed to reboot to connect new SIM to carrier services....it wasn't a new SIM. I let it reboot and everything was working with VoLTE again.
Hope this helps.

I appreciate you getting back to me. Unfortunately I am still on android 11 with a custom ROM and also this is a global phone so that app didnt work for me. I dont receive OTA updatez. I'll update to a new ROM and see what happens. Thanks
