If volte not working then here's my trick ...
First flash a rom which support volte fully like stock rom .... Now go to recovery and make backup of only EFS folder in twrp .... Now flash the rom in which volte not working and restore the efs folder after flashing the rom and now your volte will work .... And this trick will work with every rom

I think zui already support volte and there isn't any issue with volte make sure you're using the sim card in slot1
Double topic?

Miraculously I found this to be untrue!!
I have two Z2 plus phones, one on ZUI 2.5 unrooted, the other I am running ZUI 4.0.199 RuMod.
My Airtel SIM used in the unrooted ZUI 2.5 phone did not have VoLTE activated, and so I inserted into my friend's phone Redmi note 5 pro. Even there no VoLTE, so I complained to Airtel, and in about 1.5 hrs VoLTE got activated!
I then put it into the Z2+ with ZUI 4.0 and saw VoLTE working. I also then put back the SIM into my Z2+ with ZUI 2.5 and was amazed to find that Airtel VoLTE was working!!! I could make calls to others and the network did not switch to 3G.
It worked most of the day, but then in the night it suddenly switched off on its own again. I don't know if it is the Z2+ VoLTE bug or airtel switching off VoLTE, so I tried to verify by putting the SIM back in the ZUI 4.0 phone, and found that VoLTE was still active, but putting it back in the ZUI 2.5 phone did not enable VoLTE again.
I don't know what exactly to infer from this incident. Was it a error of Airtel's part that VoLTE worked, or is it the VoLTE bug that caused it to switch off on ZUI 2.5...
However, one thing is clear that Airtel has deliberately switched off VoLTE on some phones claiming unsupprted.
I have recently found Airtel VoLTE active on some friend's phones which officially do not support Airtel VoLTE like Lenovo K8 note, so I think Airtel is deliberately limiting VoLTE access...

But after a reset am unable to get the Voice over LTE even after turning the VOLTE option switching on from the settings.
So, someone please help me.. i have tried different access point settings still no help..
Restart the mobile. Or try to change the Sim card. Even I faced the same problem in Jio but after changing the sim its working fine now.
Have you update the latest MIUI 8 firmware ?
Does the problem still exist ?

This rom is fake and you need to flash the original rom and then choose english rom and use it or then you can apply for unlocking bootloader and then flash xiaomi.eu rom.
Hey everyone, I would like your attention please in solving this bug in every 8.1 ROMs. As Indian carrier user, one of my carrier is Jio and other network carrier is Airtel. In every 8.1 ROMs, I am unable to make calls from second sim if I enabled first sim as data sim. I had tried this in reverse way also means placing jio at second slot and used for data sim then also I was able to call from jio only not from my first sim. I tried without gaps flashing then I was able to call from both sims. I don't know its gapps problem or volte ims patches that after gaps there becomes a conflict and calling is not possible through non data sim. This is really a big problem for dual sim user. If anyone know any solution then pl guide. BTW I have tried this on Nitrogen, PX ROM, Lineage 15.1, omni , cosmic and other 8.1 ROMs .

Kenzo is not for airtel. It will never get volte.
Use Aosp Extended Pie.

Thank you for your reply,i didn't know that Airtel doesn't supports kenzo.
Okay,then is there any rom that supports dual 4g? Because ryt now i hv my airtel in sim 1 and jio in sim 2 with volte working...but whenever i need to call with Airtel ..my data needs to be switched to sim 1 that is of Airtel to make calls...n in this process...jio sim shows no network.
So what i want is a rom that could handle jio(volte) and airtel(non volte but 4g) at the same time so that i could use internet through Airtel 4g n at the same time receive calls through jio volte.
Help me find such rom.

I dont have airtel sim. But have u ever get that feature in miui global romfor kenzo ???
If u use 4g in one sim then other sim will fallback to 3g.
And also u must use same sim for data which u using for volte.
U cant use one sim for volte and other sim for data. U cant do this for kenzo.
If u want that kind of stuff then buy latest phone which has dual volte dual 4g.
Hey, I'm using Xiaomi.eu's MIUI 10 rom based on Marshmallow and I can't get VoLTE to work, it is available for my carrier but my phone doesn't get the VoLTE calls even if I'm on 4G. I saw some threads about this but they were about MIUI 8 and I'm afraid that I can't trust those fixes anymore since they can brick my phone, does anybody knows a fix for this problem? Thanks

Kenzo is old phone.
It was launched in 2016.
In india it only supports Jio carrier. Coz jio is the first to start Volte and 4g in india in 2016.
Later in india all other carrier brought 4g VOLTE service.
but still on other sims Volte is not enabled even though all other providers have volte too.
Xiaomi didnt care to push modem ota update on kenzo to enable volte for other carriers.
Now kenzo already ended official OTA support. So dont expect anything.
If u want volte enabled then buy latest phone coz xiaomi is bitttchh. They are selfish. They dont care about customers. They can easily activate volte by simply pushing ota update for modem. But they wont do. Coz they want people to buy new phones to enjoy volte service.
Installed miui rom on my mia1 but is was having some issues so i flashed stock MIA1 rom back . but now im not able to use Volte Service on my device 4G Airtel and Vodafone are working perfectly but for i had to use JioVoice Volte Application to make calls... i have enabled 4G LTE in network setting but still facing his issue
