Hello, maybe someone here can help me with my problem.
I have a G965F, I switched my carrier on monday from t-mobile to o2 germany. i was using soldiers's 7.2 rom and installed latest Stock DBT version today for testing. Now it is not possible anymore for me to force 4g connection and use VoLte/WiFi calling. If i force 4g, the VoLTe slider is greyed out and ims registration is not happening. If i use 4g/3g/2g or 4g/3g only, it works without a problem. Also with t-mobile force 4g and VoLte worked without a problem.
Just wanted to share my experience with WiFi Calling. I am in the US on T-Mobile and WiFi calling has been working for me surprisingly. VoLTE has also been working wonderfully. I've tested this on a Global Mi 9 running Stock and the Xiaomi.eu rom.
Enter these codes into the Dialer to enable the options in Settings. (Settings < SIM Cards & mobile networks < Sim Card Settings < VoLTE Enabled/Make Calls using WLAN)
VoLTE *#*#86583#*#*
VoWIFI *#*#869434#*#*
Things should work after you enable the two options. This depends on whether or not your carrier supports it and your e911 address set (US only?).
Some issues you might run into is that the option for Network Preference is greyed out and you will unable to change that option. I've had some success if you disable it and re-enable it and click on that option really fast, it will go through. When you first enable VoWiFi, it is important that you get into this menu and change it to WiFi preferred or WiFi Calling won't work.
UPDATE:
Manually creating your carrier APN worked great for me. Been testing it for about 2 weeks and I haven't had any issues with VoLTE/VoWiFi. For example, for me on T-Mobile, I created a new one with the following settings. The important part I'm guessing is the APN type. Also make sure that your carrier has enabled WiFi Calling on their end as well.
APN: fast.t-mobile.com
MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
MMC : 310
MNC: 260
APN type: default,supl,mms,ims,cbs
APN protocol: IPv4/IPv6
APN roaming protocol: IPv4/IPv6
On a side note, since you're on T-Mobile US, are you getting LTE+? I was showing LTE+ on my Mix 2S and Mi 8, but doesn't show up on my Mi 9.
Can verify, works with Chinese Mi 9 8GB 128GB version. I'm also on T-Mobile. Now there is "HD" written on the signal icon.

It does when I'm outside. RN it isn't showing tho, I'm in the basement. I'm pretty sure I've seen it before when I'm on the bus or something
Also works in Netherlands with Vodafone

It just randomly loses WiFi Calling. To solve this, I've been keeping my phone airplane mode with WiFi on and haven't experienced any type of disruption of service. Calls sounds great.

Worked like a charm on Romania's Orange network. Both VoLTE and VoWiFi seem to work well.
Thank you for the tip.

I don't know if it helps, but in Romania on Orange I have 4G+ almost all the time while on my old Oneplus 5T I didn't...

It's a carrier specific option. So go to phone-> settings-> Sim cards &.....-> Orange and should be the last two options.
Hmm...I've activated both too but only get the volte option, no wifi calling toggle switch. Tmobile USA running no root, stock miui 10.2.3. Did anyone on tmobile USA get wifi calling to work? Also, if you did, does it also activate wifi texting?
Update: guessing the volte doesn't require a restart but wifi calling requires a restart. To those who run into the same prob as me.
Ídem here, no volte options, my carrier support it and works on a s7 edge, any ideas?

After update to Miui 10.2..24.0 options for VoLTE and VoWIFI appears in menu and i can activate both.
unlike you, since the last update 10.2.24.0 I lost the option volte/vowifi, when I try to reactivate it, the phone tell me it's enabled for the SIM 2 but I have no sim two,
if i swap the sim card it tell me activated for the sim 1 ...
Same here, after the new update 10.2.24.0 i have the same message like you.

I activated volte and wifi calling, but when I go on flight mode and activate wifi, wifi calling is not working and there is no sign in status bar too. I am Vodafone Germany and on my Samsung it was working.
How did you get it working?

Did a quick test on mine (T-Mobile/Germany) and it's working. I just used the dial-codes and enabled wifi calling. Had to change the preferred connection type to wifi-prio though - wasn''t working with cellular-prio and flight mode before.
It works!

Download a signal app from the Play Store and make a phone call. If you still have 4G when making the call Volte is working. If the signal drops to 3G after the call connects Volte is not working.

I did It and volte is not working...
I have a Mi 9 global version running the latest stable global Room. I'm trying to turn VOLTE on, but I'm nota being sucessfully.
I've tried enable It via MCC code (*#*#4636#*#*) but It doesnt work. The option to enable VOLTE os greyed out.
How can I enable It? My old s7 suport VOLTE with the same sim card.
Hi,
I am using Mate 20 Pro (LYA-L29) in US and the firmware is 232. I am pretty sure that my carrier (not U.S. carrier) supports VoWifi and I used it on this Mate 20 Pro before while I was not in U.S. After I moved to U.S., I also updated the firmware and the Wifi Calling option has gone since then. To double check what is the cause, I inserted this SIM card into an iPhone and Wifi calling was available and worked well. Therefore, I think it is a problem of this phone.
Does anyone encounter a similar problem?
Thanks!
Different networks operate WiFi calling in slightly different ways. I know that my Mate 9 didn't support WiFi calling in the US but has done in other places without issue.

I don't quite understand why wifi calling depends on the physical place. Say I set the phone to airplane mode and connect the phone to different wifi routers in different places. The wifi standard is always the same and the phone may not be able to tell where it is.
VoWiFi and VoLTE (WiFi and 4G calling) are network and handset dependant. If a particular network hasn't authorised a particular handset, or if that handset doesn't have the specific settings needed for a particular network; then VoWiFi and / or VoLTE won't work.
I installed "Network Cell Info" to check the status of Wifi Calling and the availability of Wifi Calling is No. I notice that the devices prior to mate 20 pro have a secret menu and there is a switch to turn on the availability of Wifi calling. However, the secret menu code does not work anymore in my mate 20 pro.
This is so fvcked that despite my carrier (from which I GOT THE DAMN PHONE) supporting VoWiFI (I had it working on my S7Edge before this) and despite VoLTE working on my Mate 20P, they just won't enable it on Mate 20P.
Guess what...it DOES work on P20/30 Pro, from day 1. Go figure.
Also...got a SIM from a different carrier...bam, VoWiFi working on mate 20P.
This is madness....I'm running out of hair to pull.
PS I went as far as installing Nova launcher so I can create a widget to ENABLE VoWiFi (which normally does not show up in the Settings) but of course it does not do anything because the carrier did not enable it for the phone.
i have same problem in Israel carier
i have the volte switch but its not working.
other carier its worked automatically but their internet i cant watch youtube at 1080p

My situation is exactly the same. I have a switch for VoLTE but not for VoWifi. I also tried Nova launcher, but it did not work.
The strange thing is that the sim + mate 20 pro works in one place, but not in the US.
So i got my Mi 8 Pro yesterday (Global Version). The one feature I cannot seem to activate is Wifi Calling, I have done both the *#*#86583#*#* (voLTE) and *#*#869434#*#* (voWIFI), both options are enabled in *#*#4636#*#* and when i go into my sim settings both VoLTE and Wifi Calling are enabled
voLTE shows the symbol in my task bar however wifi calling never seems to enable? Is there some other setting I am missing or do I need to get EE to disable and re-enable it on my account since I've swapped phones? It's vital for me as I work in a lot of places without cell reception so i rely on wifi calling.
Any help is appreciated

Hello, my friend is also like you, he is the development version of WiFi can not be used but the stable version of the MIUI system can be used. You can try to re-wire the stable version of the MIUI system, I wish you good luck.
G'day everyone,
I'm using the XQ-CQ54 variant, but I couldn't get VoLTE and VoWiFI to work on Telstra. Does anyone know how to get this to work without rooting the device? I saw some folks have been able to get this to work with the OnePlus logkit. Is there a similar toolkit to enable VoLTE and VoWiFi for Sony devices?
For what it's worth, VoLTE works fine with Vodafone, but VoWiFi. Much appreciate any help.
You will need shizuku app and pixel ims apk
Got VoWifi working on mine even tho i cant get root(us model)

I have installed them both, but I couldn't get VoLTE working using a Telstra sim. Have you been able to get VoLTE working on Telstra's network?
Did you follow my guide tho https://forum.xda-developers.com/t/vowifi-and-volte-no-root-required.4566313

Yes, I tried, but that did not help. I can see LTE and VoWIFI switched on by *#*#4636#*#*, but none works on Telstra's network.
