VOLTE should work out of the box.

Have you tried, *#*#86583#*#, to see if that works for you?

4G is technically LTE. The Xiaomi firmware doesn't seem to have an LTE icon, at least not that I have seen. 4G and 4G+ are LTE and LTE-A.

thanks for the info

After the *#*#86583#*#, try going into Mobile & Networks, and select your SIM card. There should be a VoLTE enabled option now. This option didn't show up for me until I did that and then I had to turn it on.
There's now a tiny VoLTE icon in the notification bar and when I'm on a call, it stays there.

Try code *#*#869434*#*# to disable VoWIFI check. And check if it working on T-Mobile.
I don't have Tmobile to check it.

No, VoWifi doesn't work on t mobile

What ROM's have people tried for WiFi Calling? Does the OP refer to T-Mobile in the UK/EU or USA? The Global Stable seems to have some less features compared to the Chinese Stable. I had Advanced Messaging working in the default text app when I was on Chinese Stable by doing nothing but it does not seem to work on the Global Stable.

got volte working on tmobile US just not wifi calling but its fine

Which ROM is your device using? I really want to flash my green one back to the Chinese Stable. Global Stable just isn't as good in my opinion.

Eu global the lastest one 10.2.2.0

Ever find a solution to this? I am on MIUI Global 10.3 (Stable) and am able to turn off Mobile data( T Mobile is my carrier in U.S.) and with my WiFi on the device i can still make and receive phone calls. In this configuration i obviously still see my WiFi symbol in the Notification bar as well as the VoLTE symbol. Don't know if this will help you at all, but it is some stuff i have noticed recently when i was trying to figure out why T-Mobile apps dont work on my Mi Mix 3.
With WiFi turned off and Mobile Data turned on i am able to make phone calls(obviously) with VoLTE and am able to see the LTE+ symbol in the Notification bar as well.
If i go to About Phone --> Tap "Internal Storage" 4 time(brings you to the Testing Menu) and looking into the Phone Info i see the following...
Set Preferred Network Type: LTE/TD-SCDMA/UMTS
Mobile Radio Power: On
VoLTE Provisioned: Off
Video Calling Provisioned: Off
WiFi Calling Provisioned: Off
EAB/Presence Provisioned: Off
When i bring this menu up on my previous phone(LG G7 ThinQ) i see that the Preferred Network type was different...so i changed my Mi Mix 3 just to match to see how it would change
My LG G7(without a SIM inserted) shows the following
Set Preferred Network Type: LTE/UMTS auto (PRL)
Mobile Radio Power: On
VoLTE Provisioned: On
Video Calling Provisioned: On
WiFi Calling Provisioned: On
EAB/Presence Provisioned: Off
Changing the network type on my Mi Mix 3 didnt do much, however when i changed it LTE/CDMA/UMTS auto(PRL) the VoLTE Provisioned and Video Calling Provisioned both switched to "On".
I dont quite understand this so for the most part i have just left it to match my LG's setting since i can change the network type back to LTE/UMTS auto(PRL) after and the settings stay set to "On"
Made a few test phone calls after with WiFi on and off, everything seems to work just fine regardless of what the phone displays.

Put the device in airplane mode, then turn on WiFi. Can you make calls? I can't! Turning on WiFi and enabling WiFi Calling doesn't mean the calls are going over WiFi. Especially if you are still seeing VoLTE or any time of mobile network connection.
Edit: Go down to the very bottom, hit more, hit IMS status, and see what it says.

Yeah I looked at the IMIS before, voice over wifi has always(I assume) said not unavailable

No access to the IMS settimgs is more than likely why we can't get it working. We cam't see the settings to even compare them to what they should be.

I am on MIUI Global 10.3 (Stable) / Chinese Device / T-Mobile Germany.
VoWiFi as well as VoLTE are working on my device, however you need root access to enable the VoWiFi profile.
Once it is working you will see the WiFi calling icon in the status bar.
I was following this guide to enable WiFi calling on the Mi Mix 3:
https://forum.xda-developers.com/poco-f1/how-to/guide-activate-vowifi-wlan-call-t3871263
I don't know if the mentioned profile will work in other countries as well but maybe someone with more insight can shed some light into this.
I remember that VoLTE was working out of the box, you just have to disable the carrier check with the USSD code to make it available in settings.
VoWiFi can be enabled via USSD code as well, however even after changing the setting to enabled and preferred WiFi calling it does not register without the profile change.
VoLTE: *#*#86583#*#*
VoWiFi: *#*#869434#*#*
I had to redo the profile change after each upgrade with TWRP, since the firmware partitions get updated as well.
I hope this will help. :fingers-crossed:

I have Mix 3 with U.S T-Mobile service. After disabling the VoWiFi check with *#*#869434#*#*, the option for WiFi calling check box appears under the T-Mobile SIM section, but WiFi calling is not working when tested under airplane mode with WiFi enabled.

Vowifi works fine on MTS (Russia). All you need:
1. Activate vowifi service from the operator
2. Disable service check by command: *#*#869434#*#*
3. Create folder into: /system_root/system/priv-app/MBNLoader
4. Copy into this folder APK: MBNLoader.apk (View attachment MBNLoader.apk
5. Give right privileges: -rw-r--r--
6. Reboot phone
7. Install from play market QuickshortcutMaker: https://play.google.com/store/apps/details?id=com.sika524.android.quickshortcut
8. Open it and go to tab apps
9. Find Modem Config
10. Open it (tap) and you will see a lot of MCFG Modem configs.
11. Try one by one to start vowifi working
12. Enjoy!

TELSTRA Australia Users - I have VoWiFi all of a sudden!!??

Cant remember what exactly what I did, but I followed guides here;
https://forum.xda-developers.com/oneplus-7-pro/help/force-enable-volte-vowifi-t3934227
&
https://forum.xda-developers.com/oneplus-7-pro/how-to/guide-activate-volte-vowifi-t4116051
and
The later being the most recent. Whats even more surprising I have previously heavily de-bloated this rom using xXx No Limits to the extent VoWiFI and LTE feature aren't even available (but I understand changes carry forward as they are saved to the EFI partition)
Anyways, going to dive into to see what exact setting I enabled and will post back.
Any other Telstra users notice they have VoWiFI this morning?
Edit: Updated with PDC Setting for Telstra Volte & VoWiFi :laugh::laugh::laugh::laugh:

Yea, so I know have VOLTE as well!! Really a nice surprise this morning because reception hasn't been the best at home. Anyways,
I have a GM1910 (Chinese ver of One Plus 7 Pro 256Gb / 12GB running OOS 9.5.13 GM21AA with xXx No Limits magisk rom + Kirisakura custom kernel.
I have all installation files backed up as well as some are not hosted by the ops anymore.
What I need to figure out are the specific change I made to the IMEI with the qpst programs... I don't think I did anything to major in the end there, it was months ago and didn't yield any affect.
Any Telstra users have VOLTE and VoWiFi without having done anything!?
I'll post later today my PDC settings

Updated post with req. PDC setting, can someone confirm if working on their end too?

No such luck on my end. I have the same model and have tried a few versions to no avail. I have had volte pop up before, but the moment I made a call it switched back to 3G. Have you confirmed them to be working? I need vowifi, i have no reception at home. Sick of facebook calling...

I just made an additional discovery, you also need to have "My Telstra" app installed as well just as a normal app and have run it at least once then reboot. Have you tried that?
Also, in you Sim settings you have VOLTE and WiFi calling enabled?
Volte and VoWiFi are working here, during call it he phone app will advise call is over vowifi

I'm SOL.
Got a HD1913 1+ 7T Pro.
Tried everything but cant get VoLTE or VoWIFI to work on Telstra.
Running Firmware 10.0.10.HD01AA
Have all the options enabled under Sim1 and through *#*#4636#*#* its all enabled.
Unfortunately no VoLTE sign or VoWIFI when calling. HD symbol works during calls, but thats about it.
Even have the Telstra App installed and full permissions.
UPDATE****
So i put the phone into aeroplane mode and enabled only wifi, tried to do a call and it failed, then BAMMM! VoWIFI enables itself and now I have VoWIFI enabled.
UPDATE 2****
VoLTE has enabled itself too. Looks like the trick for Telstra is to go into aeroplane mode, make a call with wifi enabled only, accept that it says called failed and it should enable VoWIFI and VoLTE.
Happy Days!!!

I'm also on Telstra (Boost mobile) and managed to get VoLTE and VoWIFI working on my OnePlus 7 (non-pro version).
I followed the guide exactly as described here: https://forum.xda-developers.com/oneplus-7-pro/how-to/guide-activate-volte-vowifi-t4116051
After I did all the steps, I rebooted and VOLTE didn't seem to work at first. But then I went into airplane mode and made a call with only Wifi enabled as kw0n2k suggested above. Then VoWIFI and VoLTE started working immediately.
When I was following the guide, the Logkit app preinstalled on my phone didn't have the VoLTE switches so I had to download the Logkit APK they recommended in the post.
For the VoLTE profile, I used "Telefonica_UK_Commercial" as mentioned in the post.

VoWifi on MIUI 12?

When the phone arrived, Miui had 11 systems on it. When you switch on for the first time, the VoWifi signal also appears next to the Telecom card. Then he immediately upgraded himself to Miui 12, there has been no VoWifi since. The switch (both VoLTE and VoWifi) is visible in the settings menu, but there is no VoWifi connection. You can also see in the call list that you are only making or receiving a VoLTE call. Has anyone else experienced this, or do I just have such "luck"?

Have you turn it on?
Sim cards & mobile networks -> Choose your sim card -> Tick on Make calls using Wi-Fi.

Maybe they removed your provider's profile. Vowifi also does not work in Telekom Hungary. I can switch on the vowifi in the menu but does not work. But someone reported it works on another operator, Digi. Also you may ask your operator not to deny vowifi in some reason after the software update.

My previous phone (MI 9SE) also had Android 10 and MIUI 12, this Telekom SIM worked. VOWIFI appeared in the status bar and there was a WIFI CALL note in the call list in addition to the calls.
WIFI appeared on the lock screen instead of Telekom.
Interestingly, both phones have Global (non-EU) ROMs.

It depends more likely whether the provider's profile exists in the firmware or not, and not likely depends on the Android version.

Oneplus 7 Pro T-Mobile (GM1915) on verizon, is VoWIFI possible?

Hello,
I recently purchased a T-Mobile unlocked Oneplus 7 pro (GM1915, 8GB ram/256GB storage) on eBay to use on Verizon, and I can't seem to get wifi calling to work. We went through the setup with Verizon, and let them know it was a CDMA-less device, and everything works perfectly besides wifi calling. I do not have the option to turn on wifi calling in the settings of the phone or the log kit. When I dial *#*#4636#*#* in the phone app to get to the phone info, the VoLTE provisioned slider is enabled and able to be turned on and off, but the Video Calling, Wifi Calling, and EAB/Presence Provisioned sliders are all greyed out and disabled. I called Verizon to check on their end if it could be enabled, and he said it was enabled on my account, but it still wasn't working on my phone. He put in a ticket to verify the E911 address, but after reading a lot of threads on forcing VoWIFI on other models, I just wanted to see if it was even possible, as I saw next to no threads on my specific model of 7 pro. If anyone has any guidance for me on this issue, I would really appreciate some help.
Thank you!

Won't work. The phone is not a Verizon phone and will be refused access to the vowifi server. Only the pixel ever functioned. Sms over WiFi will work with the Verizon messages app or Google messages and rcs. You best option is Google voice for vowifi.
Welcome to Verizon where unlocked 5g phones don't work on 5g either.

Fully possable

VoLTE on XA2 Ultra H4213 ??

I have been struggling with getting a definitive answer to the question if VoLTE is possible on the H4213.
I am led to believe VoLTE is a software ability that does leverage on some hardware requirement.
After not finding the .."enable VoLTE switch" in settings on the Stock Rom but getting info from SONY that the H4213 is a VoLTE capable device, I flashed LineageOS 19.1 plus some Gapps to the Sony.
All good! Now there is a VoLTE slider in settings but still unable to get VoLTE connection. The sim is supposed to be 4G/LTE only.
When I run Network Cell Info (Device+sim) and #4636# Sim shows as ready and Network Type as LTE and in service, VoLTE ,Video calling and WiFi calling provisioned .... but Device Telephony shows Phone Type as GSM and VoLTE capable - No. Same for WiFi Call avail - No and Video Call - NO.
I have been thinking of running VoLTE-fix to see if this fixes anything but that would be of no use if the device HW is not VoLTE capable.
Anybody out there that can say with certainty that the device is VoLTE capable.
I have a suspicion that the sim may be the issue here, as I am also struggling to connect to Mobile data on the sim and the APN information looks dodgy.
This is with RainOne in South Africa, and the surprising thing is that if the number of that sim is called I immediately receive an SMS that I had received a call . SMS and Whatsapp works.
Any light on this issue will be appreciated. Ideas, thoughts anything !
Thanks
