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!
Have finally found the VoLTE settings on the phone but for some reason when I activate it using. *#*#4636#*# it deactivated as soon as I leave the page. Is this because my mobile provider (3 UK) doesn't support it on the Oneplus 3t?

Do you have the volte switch in your settings ?
VoLTE is a feature that is provisioned by your carrier. Most carriers will not provision VoLTE unless they have an open policy (allows all capable devices), or if you are using a carrier-branded phone. For the second option, lots of carriers claim that it is to ensure stability and quality of service, though I suspect that's all BS they spew in an attempt to sell more of their own phones.
Anyhow, try to find out if your carrier provisions VoLTE to unlocked/unbranded phones. If not, activating the VoLTE setting within the phone will not do anything.
I'm in an AT&T HD Voice coverage area.. never been able to use it or even see if it works. The build.prop edits seem to work for some but I've never been able to get it to work at all.. Could be AT&T blocking it of course since I don't have an AT&T device really on any of my 4 lines.. All unlocked non-carrier phones.

No issues at all for me. USA TMO.
Sent from my OnePlus 3T using XDA Labs
It is toggled on under status bar together with VoWifi but no idea how to activate it. I suspect my carrier doesn't allow it yet for this phone.
I seem to now have been able to activate it by *#800# but still no joy. I'm guessing this is due to three blocking it rather than my phone.
I use the VoLTE enabler in Magisk and once I enable and restart I have no issues. Workout it I don't get HD calling and any call I make, my phone drops from LTE to H. I'm on AT&T.
OP3T on Three UK. Been using crDroid Pie recently and i'm now able to make VoLTE calls. It comes and goes though. The options are in Settings and 'Enabled'. Phone Test shows VoLTE Provisioned. VoLTE icon show up in Status Bar.
Most of the time when i make a call i still see the Signal Icon drop from '4G' to 'H', but if i repeat dial a few times it latches on to VoLTE. I'm not sure why the inconsistency, but my 4G reception is weak and prone to disappearing entirely, so maybe that's why.
Three APN settings in ROM are same as always. No special 'ims' APN or settings.
@Eggstones
Edit: The package 'org.codeauora.ims' has been mentioned a few times for throwing up a 'Device is HD capable' Notification. I assume it's updates to this package that have enabled VoLTE?
@Dirk
I can get the volte to work fine but not the WiFi calling. I'd love to get that working ok.

It's working for me. Turned off Mobile, enabled Wifi calling and had no problem making a call. I think the necessary settings have been added to the ims packages that are commonly included in Pie custom ROMs now.
What ROM are you using at the moment?

As i said, it's working on Pie ROMs. It's not going to start working for you unless you update. It's impossible to say if the same will apply when OOS Pie is released. Maybe, maybe not.

No. I have never tried to install one. Not sure how to do it. I'm aware of various guides but haven't taken the plunge. The furthest I got was rooting some old phones.

You wouldn't need to Root. Everything else is a doddle on this phone. You might give it some thought. The obvious thing is to find out what the differences are and weigh up the pro's and cons. If Battery life is your absolute priority then OOS might be better. If wifi calling is your priority then custom ROMs are the answer. Gotta decide where you might gain, and where you might lose out.
If you decide to go for it, this is a good guide:
https://forum.xda-developers.com/oneplus-5/how-to/oneplus-5-unlock-bootloader-flash-twrp-t3624877
Of course that is for the OP5 so you wouldn't use the software linked in that thread, but the principal is the same. The equivelent software for this phone is available here. The guide gets you through the important steps of unlocking Bootloader and getting TWRP on your phone. Beyond that it's easy as Pie to get a custom ROM on your phone.
Just ask if you need help. I can link you to the files you'd need.
Thank you. I might give it a go later this week
Both my dad and I picked up the Note 8 on launch day. I had zero issue enabling wifi calling out of the box, and in fact it seems to be working quite well for me. He's not had the same success. At first it said it would have to disable Google Voice. We uninstalled the app, and had Sprint de-integrate his number with Google Voice, so that the carrier stock voicemail could be configured. That didn't work initially either, and he spent some time at the store having their tech fix it. I wasn't there, so I'm not sure what they did, but eventually they got the voicemail working. So then he came around asking me to set up wifi calling. I attempted to, only this time the setup prompt insisted that it be allowed to disable Voicemail first. But since that's a system app, I'm not sure how that can be done. And given his problems with voicemail to date, I'm reticent to let it try and disable his voicemail again.
Anybody else run into this problem? Is there some sort of fix that doesn't involve another visit to Sprint?

If you are having issues with things not working on Sprint, I first had to factory reset...all was well afterwards...make sure you have a brand new SIM for the Note 8...is it a Sprint or Unlocked device (SM-N950U or SM-950U1)

Same here. I bought mine directly from Samsung and just found out that the option to select WiFi calling is missing! I rely on this at home because we live in a valley with poor cell phone reception (I have to step to a front window to make/receive calls without WiFi calling).

Thanks. I tried searching the threads but didn't find much. Maybe I need to change how I'm searching. If I do need to "flash the Verizon firmware," where can I find instructions and will it add bloat or reduce the functionality in any way (I wanted non-Verizon because of the way Verizon changed features on my Note 5)? Will flashing the firmware interfere with the Samsung support?

I called Samsung tech support and they confirmed that this feature is not in the based version of Android but the ones distributed by the carriers. The tech suggested calling Verizon and asking them to install the firmware. Anyone know if (assuming they agree) this will be the full package, including all the bloatware, and if this will remove any features from the phone? Would the "upgrade" wipe out the phone so that I have to set everything up again?
When I bought my Note 5 from Verizon two years ago I was upset to find that they had removed the PDF signing capability that was a big feature of the Note 5. I'd really hate to lose any features on my new Note 8, after all that's why I bought directly from Samsung.

In order for you to remain on unlocked firmware to avoid bloat and keep Samsung goodies you must call Verizon to have the imei # to their whitelist and reprovisioned...I did this for Sprint to enable VoLTE when available...others with Verizon have done the same...call Verizon cs and tell them you bought from Samsung and need to have your imei # whitelisted and reprovisioned to improve network connection...if one rep will not do it, call another...do not mention that it is unlocked version...just state that you got from Samsung on a Note 7 deal...afterwards, all Verizon features will work on unlocked except vvm...Google voice is better anyways

First, I found the Google Voice shortcut for Verizon is what you thought: *71yourgooglevoicenumber
Now for my bad news. I spent nearly an hour on the phone with Verizon tech support. After being bounced around a little, I spoke with a woman who kept contacting their "Network Team" for more details, and who tried to be very helpful, but in the end I am no further ahead. In the end, they said that adding my phone to the Whitelist was "Out of Scope" because the phone was already unlocked and functioning on Verizon. She said that all she could suggest was to contact Samsung, and that Verizon tech support would be happy to have a three-way conference call with Samsung tech support (they would call) to see what could be done, and that she'd put a note in my account about this issue.
Now, if I call back and try to speak to anyone else they will see this note that that will be it. So, I'm back to not being able to make phone calls at home.

For now, I have a partial solution for the poor phone connection at home: years ago, after we had complained a lot about a poor signal at home, Verizon gave us a free "Network extender," which acts as a mini tower in our house (connected through the house Internet). It is only 3G, so I disconnected it when we had WiFi calling on our phones. Now, I'll reconnect it. The only problem is that is won't connect to a phone with VoLTE calling enabled, so I have to remember to turn off VoLTE calling when I get home, and turn it back on when I leave so that I can keep my Internet access on a phone call.
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.

That's great news! Thanks. And I wouldn't have to root, right?
Does anyone know where the stock AT&T S10 ROM is? My searches are coming up empty. Or is "AT&T ROM" the wrong search words?

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.

You should look for the G973U firmware. Thread is located HERE

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.

Oh wow. That's great! I tried the new SIM, same results unfortunately.
Maybe it's just the network out here in LA.
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.

Quick question for ya:
YOU HAVE BEEN REPLIED TO. WHY CAN'T THEY JUST REFLASH THE PHONE WITH STOCK U1 FIRMWARE?

This is absolutely not true. I just switched my unlocked S10 (u1) to the ATTfirmware and Wifi calling is working great with no issues turning it on at all.

That's great to know badbread. Did you use the link https://forum.xda-developers.com/galaxy-s10/how-to/s10e-g973u-g973u1-firmware-links-t3905852 for the firmware files.
I haven't attempted this before so I thought I'd ask before screwing anything up.
Thanks.

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 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.
Here it is:
https://forum.xda-developers.com/showpost.php?p=79156802&postcount=5
I followed those steps exactly.
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.
