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.

Hello , i have activated both, i have no options in settings.

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.
Hello I’m new to android I’ve had a iPhone for the past 8+ years. I went with the Xiaomi mi a3 and I have ATT as my service here in the USA. So I’m wondering how do I get the WiFi calling to work I need it bad!!

No guarantee it will work, but you can try inputting the following codes in Phone > Dial pad to disable carrier check (to re-enable it just input the same code again) :
For Enhanced 4G (VoLTE) :
*#*#86583#*#*
For WiFi Calling :
*#*#869434#*#*
For my case, WiFi Calling option appear but not working.
Good luck!

Don't need to reset phone, just restart if you want. Then check :
Settings > Wireless & network > Mobile network > Enhanced 4G > ON
Phone > Settings > Calling account > Sim1/Sim2 > Wifi calling > ON
Like I said earlier, may or may not work. In my case, wifi calling is still not working.

I had already sold all my Wonder codes.
WiFi calling
Update to the Latest firmware and apply the second code from the first post!!
*#*#869434#*#* for WiFi calling
Now use a carrier who supports wifi calling !!
Try this video : https://youtu.be/k7gL28bDsEo from 1:42 as a proof !!
Thanks in advance
I just followed the guide and have both vowifi and volte enabled in my wife's mi A3.
It goes without saying that I had previously enabled the vowifi in her carrier.

Pretty sure I saw a recent post here with the stock images, or you could use FirmwareFinder
Use the windows hisuite program. It has an option to rollback the firmware.
Can you tell me where in settings I can turn WIFI calling on? I have 10.0.0.177 col-l29 and I can not find it. thanks

So I just switched to O2 and my WiFi calling option has disappeared! Seems like it's a carrier thing and not a phone thing..
I asked them to enable it but it hasn't worked. Maybe contact your network and ask?
Also if someone can get the RadioInfo settings to open (*#*#4636#*#* and *#*#6130#*#*) then we might be able to force it, but mine won't open!
Good day good people. My provider provides VoLTE service for SAMSUNG, IPHONS and some HUAWEI phones. Can anyone help me with activating this service. I need activation without a rooting my phone. Thank you.

You have to call your provider support and ask them to enable you VoLTE and WiFi Calling.
You also have to enable this in phone settings

Exactly. In my case, I got my service prvider to activate the above mentioned two services. When I first inserted the SIM card into my P30 Pro and set the phone up, the VoLTE was automatically turned on. I only had to turn on the VoWiFi.
