I bought a SM-N960U1 unbranded US unlocked model, and I immediately updated it to Android 9. THEN I inserted my T-Mobile sim, and I have wifi calling. I did all of this a few weeks ago, and I never really questioned it all until today.
I'm posting this now because I read that people cannot get wifi calling to work on their unbranded model unless they flash carrier firmware.
And this is what I've found. When I make a call while connected to wifi, I see the little wifi symbol on my phone symbol, as if the call is a wifi call. I have a toggle for wifi calling, which works! If I toggle wifi calling off and make the call again, no wifi symbol on the phone symbol. When I look in settings > connections, I do NOT have items to set wifi calling and VoLTE. However, I can search settings for wifi calling and I will find the Samsung 'Wi-Fi Calling' app (com.sec.unifiedwfc 6.0.33.47) RUNNING!
So, it seems I have wifi calling working on T-Mobile, with just the Samsung stock firmware and not the carrier firmware. Which is great! No carrier bloat.
I just tested my wifi calling by starting a wifi call and then walking out of wifi range, and it definitely works! At the edge of wifi range, the call broke up, handed over to the cell tower, and became noticeably less clear. I'm stoked to have wifi calling without carrier bloat.
I might investigate further if there are some settings I can toggle over adb (wifi preferred, etc)
It depends on the carrier. T-Mobile does support all of its services, including WiFi calling, on the N960U1. Some other carriers do not. Always check with your carrier before buying an unbranded phone.
I also just discovered that toggle button text is CLICKABLE, and I can access Wi-Fi Calling SETTINGS when I tap on the wifi calling toggle's text, which gives me the option to turn on/off wifi calling, wifi/cell preferred.
So I have Wi-Fi Callng, can change settings, all in the stock non-branded firmware of the SM-N960U1.
AWESOME!

On T-Mobile branded phones that come with Wi-Fi calling, there are three options when using wifi calling: cellular preferred, wifi preferred, or wifi only.
I'm taking a trip overseas and don't want to risk making a call that uses the local cellular network. The Nexus 6 with T-Mobile wifi calling only has the first two options. Is there a way to only allow calls to take place over wifi?

nope. except you can put it into airplane mode, then turn on wifi to make wifi calls.
So I have a Sprint LG G4 I sim unlocked, rooted and then upgraded from zv6 --> zv9. I had to manually add the LTE dat settings for t-mobile but otherwise everything went perfect and works fine(data, voice, LTE). Except after filling out 911 address info, wifi calling is still crossed out on the menu bar icon. I have it "enabled" but wasn't sure if it's my carrier, wrong/missing api, or something wrong with my upgrade.
Does the wifi calling icon change when a wifi call is possible to switch over?
EDIT: it works. The user instruction manual states that the crossed out wifi calling icon means it's working but not active because not in a wifi call....strange choice but nevertheless wifi calling is working with just basic manually set APN settings.
have you been able to preserve root on ZV9?
Hi folks, I'm having a bit of difficulty or confusion with wifi calling. I'm on EE but my phone is an XEU. There was a wifi calling option that didn't seem to do anything; no icon when enabled and no obvious network connection.
So I switched to the EVR firmware, wiped the phone and set up from scratch. Still got the same wifi calling option, still no icon or network activity with it enabled.
I don't seem to have VoLTE either, I would have thought the EVR CSC would enable that too?
Does anyone have any insight on this?
Thanks.
I have been having weird issues too with a dual SIM version and EE Wi-Fi calling. Inserting a microSD card in second slot can sometimes disable Wi-Fi calling in that I don't even see the option for switching on.
Hopefully future firmware fixes these glitches as I'm really loving this phone after using iPhones for a few years .

Wifi calling and VoLTE enabled itself after a serendipitous restart today.
Did your wifi calling ever actually work without an EVR CSC or firmware @ajdjackson ?
Edit: Looks like EE had some stuff to set up on my account, problem was at their end. My account says they're setting up roaming and could take up to 24hrs so something has happened to instigate these changes.
Anyway, now I'm really wondering if I need to EVR firmware at all. Samsung's multi CSC system should allow EE's wifi calling but EE would insist that it doesn't. Can anyone chime in?
Yes - strangely mine seems to working OK now even with the sd card in second sim slot. I haven't flashed any firmware at all.

Right, after a switch back to XEU I can confirm that EE Wifi Calling does work on a non EE phone but VoLTE does not!
So I switched back to EVR and everything's working fine again.
Quite surprising since EE have always insisted that Wifi Calling is exclusive to phones supplied by them, yet I've never read the same about VoLTE.
Hiya,
Just thought I'd share my experiences...
Like you, I'm also on EE and again like you my NOTE 8 is an XEU SIM free model, in my case from CPW. I found the same issue in that the wifi calling option could toggle on and off but the setting didn't seem to do anything; no icon when enabled and no obvious network connection.
I phoned EE on 150 for support but all they could suggest was to reboot my router at home even though I told them I also have a "work's" mobile phone (iPhone 5c) also on EE and that combination does have working wifi calling.
I decided to try a test to determine if the issue was with my Note 8 handset or with my new EE 4G SIM by swapping SIM's between the two phones. The work SIM worked immediately by activating wifi calling in my Note 8. My personal SIM was active in my works iPhone for approx. 2-3 minutes with no signal before a pop-up message appeared asking if I wanted to activate wifi calling. I obviously selected 'Yes' and when I swapped the SIM's back to their original handsets my Note 8 now magically works with wifi calling with the original SIM.
It's almost as if the menu item in the Note 8 for toggling wifi calling on and off doesn't activate the sim card even though the graphic animates to show the function activated.
Anyways, I now have a Note 8 with working wifi calling.
Hope that helps anyone else with similar issues involving EE wifi calling.
*EDIT* Hehe looks like my signature is a little out of date.

Thanks Steve. Do you have VoLTE? I can't get that working without swapping the firmware for the EVR specific one.

Hmm I don't know. I know that I have 'Mobile Networks' setting 'Network mode' set to 'LTE/3G/2G (auto connect)' as opposed to the other settings of '3G/2G (auto connect)', '3G only' or '2G only' but how can you tell if a voice call is routed over 4G? Does a special icon appear as in the case of wifi calling? Hard for me to say as I have zero signal at home and very poor signal at work so in both cases my Note 8 defaults to wifi calling.
Have you tried calling EE to check if VoLTE is only supported on branded firmware as opposed to generic XEU? I know that in the case of wifi calling their website is very explicit in stating that wifi calling is not only supported on EE branded/sourced handsets but also works on certain generic handsets such as S8 / S8+ & Note 8. Their website on VoLTE or as EE term the service '4G calling' is not so clear...

This EE Community Forum post seems to lay the blame at Samsung's door as opposed to EE's...
https://community.ee.co.uk/t5/4G-and-mobile-data/VoLTE-on-Samsung-Galaxy-S8/td-p/559521
Reading the thread fully, it seems VoLTE is only available on EVR and not XEU.

Yes, this shows the VoLTE icon which appears whenever I have no wifi or I disable wifi calling.

The discussion on EE you linked is interesting, so they do limit VoLTE to their own supplied phones. I'd recommend switching to an EVR firmware, despite the guy who says there's no advantage for the user, I've found VoLTE very useful, especially in conjunction with Wifi calling. VoLTE/Wifi calls are so much clearer, they can seamlessly switch if you lose the wifi signal and they seem to connect a bit quicker too.

Ahh there is a symbol, thanks for sharing the picture. I can confirm that do not get VoLTE and whilst it would be good to have every function that I pay for working the fact that I get zero 4G signal at home and at work where I spend 90% of my time means I'm not realistically going to miss VoLTE as my phone now has a working 'wifi calling' service. I suppose that if EE ever get round to providing coverage in the blackspot that surrounds my home location then I might consider swapping to EVR firmware. I won't hold my breath though because in the 20 years that I have lived at my current address, EE and Orange before them haven't bothered with trying to provide adequate cellular coverage.
I remember going through exactly the same crap with my Samsung Galaxy S2, Orange firmware got an app called signal boost and the vanilla xeu firmware didn't and we had to do a number of things to get the app ported over to XEU. Seems like no matter how much technology advances over the years some issues never change.:silly:

I have a house that gets no cell signal (from any provider, I think), and I just found out ATT hasnt enabled wifi calling on the Z3 play (I think). The house has broadband internet, just no cell signal.
Has anyone successfully used WiFi calling, and with what provider?
Also, are there any other options besides expensive microcell tower boxes? ( Microcells seem like a bad option because the family uses several different cell companies)
Thanks in advance.
Republic uses wifi calling through their app. I use at work where i have no wifi signal.
T-Mobile WiFi calling works.
Yes t-mo is the way to go.
Can anyone confirm wifi-calling is working on Verizon?

I dont find a way with Verizon
T-MOBILE has WI-fi calling.
Sprint does for sure. their Wi-Fi calling takes it a step further, in that when transitioning or leaving Wi-Fi, while on a call, it is a seamless transition. (ie. The call does not drop connection, because it is always connected )
Not a question, but an FYI.
I bought the dual sim version (CLT-L29) of the Huawei P20 Pro in the UK, from clove.co.uk
FYI (hoping it’s useful to other people): I have tested it with the 3 major networks in the UK, and wi-calling works with all 3, even if the phone is an unlocked dual-sim version, not bought from the networks.
At least where I use it, Vodafone has the best indoors signal. Outdoors, Vodafone and EE are about the same. Three is by far the worst, both indoors and outdoors.
EE: I get no icon about wi-fi calling, neither in stand-by nor during a call, but I am sure wi-fi calling works because I managed to call while in an underground station, where there was wi-fi but not mobile signal.
Three: no icon that wi-fi calling is available, but the small text “wifi” appears when making a wi-fi call.
Vodafone: icons and notifications about wi-fi calling being available come and go multiple times. Sometimes I can get 4 notifications, with the phone vibrating, in 10 minutes. It’s very annoying. I had to go to setting -> apps -> more -> show system processes -> phone -> notifications -> wi-fi calling and disable all the options (display in status bar, etc.) to make sure I don’t get these continuous notifications. However, I tested wifi calling in an underground station, with a wifi connection but no mobile signal, and it worked.
In all 3 cases, I enabled wifi calling opening the dialler -> 3 vertical dots at the bottom right -> Sim 1 (or 2) -> wifi calling
Wifi calling was already enabled by default with EE and Three; with Vodafone, it was tricky: I tried enabling it from the Vodafone website and from the Vodafone android app, but it didn't work. What worked for me was the online chat with Vodafone's support, who enabled it on their end. Odd.
Another thing I noticed is that, on my old Samsung Galaxy s7 edge dual sim, only the sim which connects to the internet could have wifi calling. Here no, both sims can have wifi calling enabled at the same time.
Wait till your on Android 9, i deffo get a Wifi calling on this.
I didn't understand - what did you mean?
