VoWifi Works on MiUi 10.3-10.4/Developer
- Thread starter gsser
- Start date
I tried this with my MIX 2 and didn't work.
What I think is when you enabling the mobile radio via the toggle actually your call is going via GSM/UMTS/VoLTE (whatever you are using) but not WiFi. The mobile radio is switched on but without indication in the notification bar.
If you do all these things to make WiFi call it means that your operator doesn't support Xiaomi devices offcially for VoWiFi. So may be you have to activate WiFi call service via customer service (or other way). Do you have active WiFi call service under your subscription? If yes, may be you can check with your carrier whether particular call is WiFi call or VoLTE call. If the answer is No, this call is not WiFi call.
As I know when you make a WiFi call the whole communication goes through WiFI directly to the carrier's IMS and you don't need to turn on the mobile radio.
I'm curious if you can try to make a call in place where you have only WiFi coverage but not GSM/UMTS/VoLTE one.
If you succeed then I'm wrong.

My carrier doesnt support officialy but also it isnt supporting oneplus where vowifi was working
I agree, but for activation VoWiFI in One plus you have to make some settings in the chip using some Qualcom software and activate different profile.
Still I'm curious did you manage to test your way for activation of WiFi calling in MI Mix 2 on a place without 2G/3G/4G coverage but with available WiFi network?
I hope I'm wrong and you are right but...
I can tell you that, my phone signal strenght is really low in my home on some places due to thick walls. Usually i get 2g if im lucky 3g, when i do this i hear others loud and clearly.
Someone else told me it didnt work for him so yeah, it may not work on some people.
Finally I found a working decision (with VoWiFi icon, successful calls in airplane mode etc.).
I'm with latest Global MIUI 10.4.1.0 Pie, without root.
All steps are very simple and the responsibility is all yours.
P.s. I cannot post external links, according to forum rules. You can find the tutorial in 4pda forum (Запускаем VoWiFi на Глобальной бете с Андроид 9) under MI 6 part but it works for the last Global Stable for MIX 2 too.
Simple guide (or what I did):
1. Install "Power Shortcuts"
from Play Store (may be some other similar program will also work, I don't now)
2. In "Activity" tab push the gray arrow and find "Modem Config"
3. After find it push the green arrow to create a shortcut
4. In the newly created shortcut "Modem Config" scroll down to Netherla and choose/tap it
That's all I did and now I have fully worked VoWiFi
P.s. Ofcourse you must have this service activated on your subscribtion plan.

I'm glad to hear that.
I'm just curious, which is your operator and which country did you choose in the modem config shortcut?
Im using vodafone turkey, chose netherla as it is the only config that has vowifi
Still call connecting through Network Provider
I can call even on plane mode with or without wifi. Calls always getting connected.

If you want help you need to explain with a lot more details what you are doing (like does your operator has support VoWiFi, do you have this service activated under your subscribtion plan, your MIUI version...etc.)
If you just make an ascertainment, sorry to hear that you have nonworking service.
Perfect :good: many thanks to Minotavur! 
It really works on my MIX2 @ German provider O2/Drillisch
(no root, standard EU image, MIUI 11.0.3)
