Hey guys,
I suppose I'm not purporting to have the step-by-step solution, but rather a potential solution should this be investigated by someone in the know? I'm trying to look up how to do this myself.
The only thing really holding me back from using this phone is the lack of support for WiFi calling. Otherwise, the recent phh-treble ROM has been entirely sufficient for me. I recently happened upon this thread on Reddit:
https://www.reddit.com/r/tmobile/comments/6yvu29/project_treble_and_wifi_calling/
It would seem that the only thing necessary to enable WiFi calling, you need a proper carrier configuration:
...T-Mobile uses a standard VoLTE / VoWiFi implementation working out-of-the-box in AOSP when the proper carrier configuration is included...
...It mostly requires the appropriate CarrierConfig vendor.xml overlay and a working AOSP build...

At first I assumed ROM developers would have to do potentially annoying proprietary stuff.
I'm almost wondering if a vendor.xml with an appropriate configuration could be ripped from a working device with WiFi calling (e.g., my old XZ1 Compact) and be repurposed for the Mix 2S.
Thoughts?
It's possible Xiaomi doesn't have enough US customers to enable this feature in the US. I've had 4 Xiaomi phones that I've used on T-Mobile--MI Note 3, MI A1, MI Mix 2 and MI Mix 2S and WiFi calling worked on none of them including the MI A1 which ran stock Android instead of MIUI. But MI A1 owners who ran LOS did report that WiFi calling worked on their phones. I'm sure it's doable but probably not as simple as copying an XML Profile from another phone. There is no option for enabling or disabling WIFI Calling in the Global ROM. The ROM you are running would presumably need to support WIFI Calling in order for it to work.

Which Xiaomi phones you have can work with Tmobile's Volte? I suppose Volte on Tmobile requires a B12 and Tmobile's authorization, maybe? Am thinking about buying A2, Redmi note 5, Mix2s or Mi 8 ...
Thank you!

Mix 2 and Mix 2S both have voLTE on TMobile. You have to enter in a dialer code on the Mix 2S to enable it though.

Thanks to Ulver for helping with this. So how will you know if you are connected to Volte? Does the screen shows the word "Volte" on the upper right corner when you are connected, like one of my xiaomi phone used in China when I traveled?
Anyone has Tmo's volte and wifi calling experiences with Mi8, Mi Max3, Mi6 or even Vivo nex and Oppo find x? I really like these phones and am considering buying one of them
PS it looks like Tmobile Volte doesn't require Tmo side's authorization or support, as many chinese phones that are not sold in the US have Volte support. Wifi calling maybe is now the only one that needs Tmo's bake-ins. Thoughts?
You can see the voLTE icon in the status bar. Unfortunately, WiFi calling is a no go.

I think Volte worked on the MI A1 as well.
If you use a signal app it will show you have 4G. If you don't have working Volte when you make a call the data changes to 3G until you end the call. If the data stays 4G while you are on the call then Volte is working.
If you use an MVNO whether you get Volte can be a crapshoot. I use Mint Mobile for my primary service. Mint Mobile does not officially offer Volte but I have always gotten it on a variety of different phones. Mint Mobile does officially offer WiFi calling but they can't tell you which phones it will work on. My backup/emergency phone uses SpeedTalk which is another T-Mobile MVNO like Mint Mobile but there is no Volte or WiFi calling.
My old Mi5 got VoLTE but no Xiaomi and Wificalling :/
It's so weird, my original MiMix had wifi calling, but the new Mix 2S doesn't, they removed it from latest MiUi's.
There used to be a way to implement WIFI Calling in the MIUI dialer but I don't think the feature worked for most people even after it was enabled. Hopefully they will at least put it back in the Global ROMs but people have actually been asking for WIFI calling on Xiaomi phones for years. I've owned a MI Note 3, MI A1, MI Mix 2 and MI Mix 2S and none of those phones had WIFI calling--although people did claim that WIFI calling worked on the A1 if you ran LOS instead of the native stock Android ROM. But the MI A1 is an Android One phone that runs stock Android instead of MIUI and it didn't have WIFI calling.
In Mi A1, of running stock Android One then just open the stock phone app ( play.google.com/store/apps/details?id=com.google.android.dialer )
Tap on three dots at top right corner > tap on settings > tap calling accounts > tap the sim ( service provider) and you'll get Wi-Fi Calling option.
My umidigi one pro does vollte And wifi calling out of the box.
It probably a feature they decided to leave out. And a deal breaker for me exactly why I have a umidigi and not a minute mix 2s now
That phone would have been my choice but I had to return it because the Umidigi needed charging 3X a day and I don't play a single game. (charging is fast, but I'm not always near an outlet and I didn't like the capacity meter -- it would say I had 10%, I'd presume I had a few minutes, and it would suddenly go dark). MBJBDC, has that been your experience?
I was impressed enough that I'll keep an eye on Umidigi in future but I ended up replacing it with a Redmi Note 5.
I can't enable Volte on the Redmi -- it's grayed out. (I shouldn't have been able to enable it on the Umidigi, technically, because I am ATT prepaid which doesn't include Volte or wifi calling).
If you go with the Redmi Note 5 in the U.S. be sure you get the whyred version, M180327sh, which has FDD LTE Band 2 in Addition to Band 4. No trouble getting FDD LTE at all in an area with few towers (once I made a bunch of settings changes).The Note 5 quality is fantastic -- apart from lacking a USB C port, better functioning hardware in general than on my Mi Max 2 -- supposedly a better Xiaomi. Even the camera was a pleasant surprise. But I am disappointed about wifi calling. If Umidigi can do it, why can't Xiaomi?
I have WiFi Calling working on Mix 2S with T-Mobile. Albeit with a Project Fi simcard in slot 2. Confirmed by putting phone in airplane mode, connecting to WiFi and dialing out using the "Hangout Dialer" app.
Not working, it's locked.

that's voIP
This phone does support WiFi calling.
It does not however support US carrier WiFi calling configurations, as the profile must be programmed into the radio for it. I have undergone extensive radio enablement, and cannot get it working.
Since Xiaomi doesn't sell their phones in the US, I guess we're lucky to even get the global LTE bands in there.
If you have high speed internet at home, get the cellspot v2. It's $25 deposit, and works great. I had to make that move unfortunately, but glad I did.

I know this is ao old thread but in case anyone else is having difficulty activaring wifi calling it works fine on all three of my xiaomi phones (redmi note 5, mi max 2, mi max 3). I have tested all three on ATT and TMO as well as safelink (tracfone) with att and tmo configured sims. it also works with Teltik (a tmo business reseller).
I actually thought it wasn't working because when I entered the provisioning menu using *#*#4636*#*# wifi calling is grayed out. However you can toggle wifi calling on and off with *#*#869434#*#*
(the option is still grayed out but you get a flashing message saying carrier wifi calling is turned on.) anyhow just turn data off and make a call to test. Although I have heard e911 had to be set up first, I can only presume the carriers did it for me since all works as it should.

Cann you tell us where you found those call codes? Is there a datasheet. That would be amazing :victory:
I'm sorry it was a forum post but I cant remember which forum. There are lots of Play store apps with codes ... Might be one geared specifically toward Miui but Ive used the general apps and quite a few of the codes work. Note: the codes only work with the stock Android dialer. It is too bad that the Xiaomi sponsored Miui forum is so useless for finding valid, current info. Even when you get results using Google to search the links are always dead (although most are cached in google and Yandex). Good luck!
Hello to you all. I would like to know if the Pixel 4a 5G supports VOLTE and Wifi Calling on the Three network in the UK. I note that they only list the 4a on their website so my fear is that if I were to purchase a 4a 5G that these network features wouldn't be available.
Many Thanks in Advance

I would assume it would be available if it shows for the 4a5G.
I know here the wifi calling is an option within the settings of the phone but to get volte i had to contact my provider to make sure they have the setting enabled for my service. Only way i can tell if its working is when making a call i see a HD icon. Also if you go to your recent calls within the phone app you can see the HD icon next to the persons name.

Three don't actually do the 4a 5G they just do the 4a so I need someone who can tell me if these features work
suggest you go to Pixel 4a 5g forum for your answer. This forum is for Pixel 4a only, not the 5G version.

Oh I didn't see that there was one for the 4a 5G sorry. That would make more sense if i posted on that forum
I have now got a Pixel 4a 5G and I can confirm that VoLTE and Wifi Calling are both working with this handset on Three UK.
Hello guys,
Finally the good news (at least for us in Saudi Arabia) Google has activated Volte & 5G on the latest Android 12 beta (May.2021)
But i am still waiting for the Vowifi activation
If anyone living in different countries can confirm as well
Thanks.
Update: in Android 12 beta 2 it was disabled again
What a stupid decision making
Good news bro
No change in Belgium (Orange, Proximus) with A12 Beta 1 , no VoLTE, no VoWifi
Same for Portugal(NOS) even on Beta 1 VoWiFi and VoLTE remains locked
VoLTE working here on 3 Austria too, don't have 5G enabled on my plan anymore so can't comment on that.
No luck with kuwait Stc
Anyone tested this in Hong Kong yet?

Is it still working after beta 2 update?
Anyone for uae ?
VoLTE & VoWiFi in Poland still blocked. Tested on Polkomtel and T-Mobile carriers.
It didn't work in Android 11 too...
The same for Orange BE, Proximus: VoLTE & VoWifi not working (A11, A12B2)
And we are in 2nd half of 2021..
I guess if Android 12 does not have the voiceover LTE then moving to root is the only option we all are left with. I am going for iphone anyways once it is confirmed that a basic feature of voice over LTE still does not exist after Android 12. Google pixel has been a terrible experience in advance times.
So there is a July security update which has a voice over LTE support for certain networks. Definitely not Middle East because I tried still not working I think it's just for some USA carriers
I enrolled in beta and on 2.1. Well the request still goes to deaf ears for Google.
Sorry on beta 3 but still no volte. Makes it clear that it's time to move to custom ROM and make the most of use of this phone now.

did you find any custom rom with volte working for you ?
No but I am currently up to two things.
First is that I am on the process of selling this phone on a local classified online.
Second is to check by rooting the phone.
I don't think any of the custom rom supports voiceover LTE by default. You really have to use the magisk by rooting the phone.
Pixel 5 will be totally last Google phone which I bought.
Official build of Android 12 comes this morning to my device, 5G, VoLTE, VoWIFI all these features still LOCKED!
Google is not a company which I can trust anymore.
Hello guys!
I have semi-functional pixel. It doesn't get radio signal and mobile internet.
In an unofficial service (don't have access to official right now) i was told that problem in this chip.
Already spend few days in google and found nothing
So does anyone know where i can get it?

hi, im also looking for that IC i know the pixel 3a xl and pixel 2xl have the same PA IC, i have many pixels here to repair with radio off.
i have 3a xl, 4a, 4a 5g, i will try to fix the 3a because i have a 2xl donor board.
By now i have the data sheet.
