I have the Unlocked A9 and I'm using it on T-Mobile USA.
Setting--> Mobile Data--> Voice over LTE is checked.
VoLTE worked with original firmware, but with the November Security Update (639737.6), it no longer works for me. (VoLTE = calls made under 4G LTE. When I make phone calls now, it changes to 4G even though I have 4 bars 4G LTE).
Please let me know if it works for you. Thanks.
I'm still waiting for my unlocked A9 for use on T-Mobile, so I can't give you another example.
I have read that there is no such thing as 4G voice, only (4G) VoLTE. (4G = LTE = data only.) If it is 4G (i.e. data) and doesn't support VoLTE then it must be using a 2G (GSM) band for voice. If it is showing 4G when you are talking then I think it must be VoLTE. At least that is how I understand things.
I'm on the latest ota update for the unlocked version and VoLTE works fine for me. I was concerned unlocking the bootloader would change that but i just completed that and calls still go over lte
In fact I've left my phone in lte only mode for the past week

Thanks for the input. Based on our info, I'm surprised that VoLTE does not work for me. When I make a call the 4G LTE goes to 4G meaning that it's a GSM call (not through data.) (LTE Discovery confirms this, as the LTE radio shuts-off during the call.)
I might factory-reset my phone and start from the beginning. Not happy, since this is hours of work...

Have you tried different cell sites? Perhaps your phone finds the current lte connection to be unsuitable for volte.

Could be, but I have a Samsung Avant sitting next to it, and the Avant's VoLTE works while on my A9 it does not. Speed test results are similar for the phones, so I know that the connection is good.
Just got off the phone with T-Mobile, they transferred me to HTC tech support. HTC wasn't much help (just reading from a computer screen). The tech promised that a level 2 support person would call me in the next 24-72 hours.

Thanks for all your help. When I read that you are on the latest ota update and your VoLTE works, I suspected it was my phone. Well, I factory-reset my A9 this morning, and VoLTE works now.
BTW, no call from HTC. You would think that they would be interested in helping buyers of their new flagship phone, but nothing.

I think they are buried. I have tried emailing them this week about accessories, also tried their chat support, and just nothing. And still no shipping date for my unlocked garnet of 23 Oct. I really don't think they were ready for this introduction and the demand that followed. I just hope the phone is worth it.

I like the A9 a lot. Coming from a Samsung S4, the signal strength is OK, but I am very pleased with the battery -- it last all day for me. Screen is bright, camera is good, and it has the latest Android.

can you tell me your apn settings for t-mobile on a AT&T unlocked a9?
Anyone else seeing a bunch of Verizon apps when browsing their app list via settings on the unlocked model? I'm on T-Mobile and yet have Verizon Login, vzw_api, VZW_multicast_mw, vzwapn, vzw oma trigger (cannot be disabled). What gives?
My guess is that Google put these in there since the Pixel was built to work with Verizon as the "exclusive" carrier. But it still doesn't make sense since Verizon dabbles with the software on their version anyway.

The ones that come pre-installed are for WiFi calling, VVM, and Video Calling.
Both models will install extra apps from the Play Store if setup with a VZW sim-card.

I've read that the answer is yes, WiFi calling should work for both Verizon and T-Mobile on the unlocked Pixels. I don't know how to tell if it's working on mine. I have an unlocked Pixel on Verizon. If someone knows how to tell, please let me know and I'll check.

Put it in airplane mode, then turn wifi back on and try to make a call.
On my Galaxy S7 I first had to enable wifi calling. Verizon does wifi calling differently from everyone else, it is part of advanced calling, and that is why I am dubious that it works on the unlocked version.

oddly i dont see them in my apps list (I'm on unlocked from google store version), but I DO see them when I scroll through my lists of apps in the battery optimization menu. I just randomly noticed this like 20 minutes ago for a totally unrelated reason. also, screw verizon.

I enabled WiFi calling, put it in airplane mode, turned on WiFi, and attempted to make a call. The phone told me to come out of airplane mode. I checked the settings and saw that WiFi calling was set to prefer cellular network. I saw no way to change the preference to WiFi. Seems it will only do WiFi calling if there is no cellular coverage available.

Other carriers let you change the preference to WiFi, but not Verizon. I've had that message before and had to reboot and try again on my S7. If you are on a poor cell signal, the phone will switch to WiFi, and you will get a small WiFi icon on the call screen. If I answer a call in my house with the cell radio on, it takes about 3 seconds to switch over. During those 3 seconds the person I'm talking to is saying "hello," "hello." So, I try to leave my phone in airplane mode with WiFi on when at home.

This is all it takes for me. I don't know about receiving calls via WiFi yet though. I doubt that it made a difference, but I'll mention that I partially set up my Google Store purchased device over WiFi before turning it off and inserting my Verizon SIM. I didn't log into any accounts while on WiFi, only after putting in the SIM. It also updated from build NDE63L to NDE63P, and I have some VZW specific apps as mentioned, but they're not in the app drawer.
Anyone know if the US or international models have WiFi enabled calling? I am ready to switch from Sammy to Weiwei if it does. :silly:
No support that I can see on the international version (used in UK). VoLTE is there for Three here though (not EE).

He asked about Wi-Fi calling on the mate 9, not band 12 or VoLTE which is what the link you posted is referring to, not even close to the same thing. The mate 9 does not support W-Fi calling, no way around it. Probably never going to have it unless they implement T-mobiles IMS settings. There are a few unlocked phones that support it, but really all that means is that they cooked t-mobiles settings into their rom, and if you read there are not really all that many that are actually certified by t-mobile mobile to actually work properly.

Yes the Mate 9 is not supported, but there are many "unlocked" phones that T-Mobile doesn't sell on that list that support WiFi calling on the network (i.e. Axon 7, Pixel, Nexus, LeEco S3, OnePlus, etc.). That was the point of my response......
ok, on my phone (MHA-L29/B197 EU version) i was able to set a link for W-Lan calling with Create Shortcut app! Search for "wi-fi calling" in app area "observe activities ->dangerous"!!
Hello All,
In my new home is very low T-Mobile signal strength.
As i know from carrier official page, T-Mobile supports VoLTE and VoWiFi (Wi-Fi calling) in my country.
Now (6 july 2017) i have installed newest LineageOS build. There no option to enable Wi-Fi Calling/VoWiFi, but regarding to official Qualcomm site Osprey's processor (Snapdagon 410) supports Wi-Fi Calling/VoWiFi:
Next-generation Calling Services
Voice over Wi-Fi (VoWiFi) with LTE call continuity
HD Voice over 3G and VoLTE
It is posible to enable Wi-Fi Calling/VoWiFi on Osprey?
This solution does not work. When i make Wi-Fi Calling enable it going back to off.
Device: Moto G 2015 (XT1541)
Country: Poland
Carrier: T-Mobile
ROM: LineageOS 14.1 build from 6 july 2017

FYI For U.S. prepaid T-mobile accounts: T-Mobile may require address and other information to be entered on their website into the account profile for that phone #. If that information is entered on-line and the account has WiFi calling properly enabled it should work when the device has wifi connection and no cellular connection. This is not dependent on any settings on the phone and should work even if you don't see any settings there. You might want to contact your provider about this.

No, it doesn't work, not with T-Mobile. It won't stay on, no matter what you do.
I have MetroPCS/T-mobile USA, and I have had the exact same issue. I've had no problems using wifi calling on my same account with other phones, but not this one (they do require you to register your full info here, as the last poster said). T-mobile support themselves have told me, however, they only allow wifi calling on phones purchased directly from them, and that's why no go, at least not in the USA. I'm assuming that's their policy in other countries, too?
I don't know if there is a hack/workaround.
Side note: When I go to Europe, which is often, I re-register my old, official t-mobile phone with t-mobile usa, leave my US sim in it, and I use that phone thru wifi calling to still have a US phone while there. I throw a UK sim in my Moto G to use every day.

From what I understand, I could be wrong though, T-Mobile open sourced their WiFi calling and anybody can implement it but LineageOS haven't done it yet. It's a matter of adding the code (just like VoLTE) I think. I don't think T-mobile checks if it's their phone or not, the right software need to run, that's all. The problem is that the software is very low level and needs to part of the kernel, you can't just install some app and make it work. This is what I found when I did my search for LineageOS and WiFi calling a few months back. from T-Mobile forums. Of course anybody can post anything in those forums so it's not official or anything but a few users provided the same answer (some seemed quite knowledgeable) so I believe this is it (probably better than talking so some phone rep reading off FAQ's haha)

It's not unheard of for mobile providers to do just what I'm suggesting t-mobile does. In the UK, for example, Vodafone limits WiFi calling even further than that, to only a few select Voda-sold models (or at least it was like that when I was there recently).
I would very much appreciate being pointed in the direction of guidance by anyone who's been successful in getting it to work on any non-tmobile handset, custom ROM/kernel or not. Thanks much x

Hi IronTechmonkey, at first I took it as a fact but later I thought about it and now I'm thinking how would WiFi calling work without LinageOS having code for it. Once you're outside of their network and T-Mobile (others too of course) can't get to your phone through SIM card the only way for anything to work is if the software on the phone through the internet first contacts the provider, correct me wrong but how would the provider get to you? This is just my thinking about it so I'm not sure but what common sense tells. I have the address on T-mobile and everything setup but since I'm not NJ where coverage is everywhere it's not easy for me test it but I'm scared without LineageOS actually getting on top of it and implementing the code it's not going to work. I'll test it once I go somewhere with no coverage but haven't had a chance yet.

Good question. I wasn't being quite clear enough in replying, and was speaking to whether or not there would be settings in the ROM if the feature exists, but was not speaking to whether or not the code is present. To the point of your question, from general web searching this seems to be device/ROM-build specific but when I search specifically for Lineage OS Osprey wifi-calling I find this thread. LOL. Apart from that this jira ticket for a different device is all I can find: https://jira.lineageos.org/browse/BUGBASH-508.

Thanks, so I'm confused now, and thanks for your help. I know with VoLTE it was such a big deal we had whole posts about removing it and then bringing it back etc... all the updates and drama we need while nobody mentions even once if this device has wifi calling or not, haha, weird
I want to reopen this thread, I tried to ask in the official development opsrey thread but was sent to Q & A, so I'm reopening this thread. Anybody knows anything about Wi-Fi calling for osprey and LOS? Will it be implemented? Can I make a request somewhere? Maybe just switch to LOS 15 when it's official, will it have it on the arrival? I traveled outside of the US and did different tests and couldn't get Wi-Fi calling to work? Here's my post from the official osprey development thread with more detailed, thanks you, https://forum.xda-developers.com/showpost.php?p=73769962&postcount=5299
BTW, I made all necessary changes back in the USA with T-mobile to make Wi-Fi calling work, thanks.
So, WiFi Calling is unavailable as default option on any of ROMs for our devices.
BUT
For example, in Poland everybody who has Android higher than 4.1 can use "WiFi-calling" on "Orange" carrier. This carrier offers some application which realy works:
https://play.google.com/store/apps/details?id=pl.orange.vowifi&hl=pl
Functionality of this app is same, but i think it drains more battery than "wifi-calling" implemented as driver in kernel.

Thanks mrViZhy, actually I'm traveling from USA to Poland too. What I would like to do is keep the US number and receive text message (and pick up phone calls too) from US. I'm assuming your solution requires getting Orange number, if that's the case it would break the connection that I have with the US.
Thanks again for your help
Does the US version support US T-Mobile VoLTE without reflashing mixing US oem.sin into foreign firmware?
You'd need to be on US region firmware to use VoLTE. For example, I flashed my Xperia 1 (J9110) to J8170 and everything works, including VoLTE - except for the 2nd sim.
It's carrier depending. The Sony is cable.

Silly me. I didn't realize this isn't out yet. GSMArena indicated October release, and I assumed it was already out and came here.
I suppose we won't know if the Xperia 5 sold in the US (ie Amazon, BestBuy, Adorama, etc) will support VoLTE out of the box. XperiFirm shows:
J8210 (listed in GSMArena) - UK & Ireland
J9210 (listed in GSMArena) - Europe, UK, Russia, Taiwan, HK and China
J8270 (listed in GSMArena) - Not found in XperiFirm
SOV41 (not mentioned in GSMArena) - Japan
901SO (not mentioned in GSMArena) - Japan
I suppose it will support VoLTE, as I read in the past in another thread about how the international firmwares recently started including VoLTE for the US. I am still on the XZ1 Compact, so I don't have any personal experience.
EDIT: Sorry, the thing about US VoLTE support in international firmwares might have been from the Samsung threads. I've been researching the S10e and Xperia 5 as my next phone after my XZ1 Compact, that my brain is fried.

Any chance that WiFi calling works as well? I'm seriously considering this device as an upgrade from the XZ1 compact. I'm probably hoping for too much here as that would have required a certification.
Unfortunately WiFi calling is not showing up for me on T-Mobile US. I can't remember the last time this was an issue. I'll call them later today to see whether the plan on whitelisting the Xperia 5 for WiFi calling.
I also can't tell if we're actually using VoLTE or not. The option is there in setting and LTE stays connected during a call, but I'm not certain whether the call is actually connecting nicer LTE.

I just made a call and watched the app. Unfortunately I remained on Band 4 during the call. Sounds like this means the call was not using VoLTE. Very disappointing.
Just received a call and there phone app said the call was over WiFi. That setting is nowhere to be found so that's interesting.
The person on the other end did confirm a echo on speaker phone, though. Not sure how to get rid of that.

Thank you. That's an interesting find. Also, I wouldn't expect the phone to switch during a call from band 4 to band 12. The only way to see would be to find a spot where you're on band 12 and see if it switches away during a call. It should stay on the strongest signal band.

Ah, I misunderstood your point about band 12 originally, apologies. I received calls yesterday and today and the Phone app says "calling over data," so I guess that is how they're saying VoLTE. I swear the terminology shown for both VoWiFi and VoLTE was different on my OnePlus 7 Pro.
In summary, for those skipping to the end, VoWiFi and VoLTE seem to work (on T-Mobile USA) even though it's not obvious.

Any chance that WiFi calling works as well? I'm seriously considering this device as an upgrade from the XZ1 compact. I'm probably hoping for too much here as that would have required a certification.

Hi, has anyone been able to fully confirm VoLTE/Wifi Calling for T-Mobile? Thanks.

VoLTE is available and works
I do not think WIFI calling is enabled/allowed on this phone.
I could not find wifi calling settings to enable/disable on the phone, so i did some tests to check if it works:
1. When I call within a WIFI network and TMobile off, the calls wont go through.
2. Also, when everything is on and I am connected on WIFI but very poor TMobile connection, I do not see WIFI calling

There is indeed no option to enable this but WiFi calling does work on T-Mobile USA.
I bought the phone last week. I compared the bands and connectivity with my XZ1 Compact. It definitely has VoLTE including band 12, but unfortunately it does not have any working WiFi calling on Tmo. No option and it doesn't make calls or texts on WiFi only connections.
I will say that it does seem to have a slightly better signal strength than my XZ1 Compact had.
Bump for any updates?
I get calls in lte mode so yeah I'd say USA volte works
