Helloo guys am from India and recently imported a redmi pro with a global rom MIUI 8.0.7(LXKCNMA) when i first used a 4g sim i did get the option of Voice over LTE nd able to call ober 4g network. 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.
So I got my Airtel number ported to a Jio sim card. Put it on sim slot 1. I'm getting to use data services but cannot seem to activate volte/enhanced 4g mode to make calls at all. The option isn't even visible in the mobile networks menu.
I also checked my sim info and it says 'volte provisioned' but there's volte option in the settings.
Since I'm not able to activate volte, each time I try to call from the Jio sim, it fails.
Also, I'm running the stock debloated ROM from Sandy and I'm rooted.
I've used V1 of this ROM before and volte was working fine. I just wasn't rooted at the time. Can root be a problem? Please help guys.
found anything ?
hey man did you find any solution to this problem yet?
Same issue- stock rom unrooted Airtel only
Quote me or hit thanks if you find a solution so I get a notification
Hi,can someone suggest me a pie rom for kenzo that can be a daily driver for me? All that i care about is a stable pie rom with good battery+gcam(night sight too but not a deal breaker).
Ps: i'm currently on pixel experience 08/2018 build ... it's quite good but i can't use Airtel volte on it...and also dual 4g doesn't work too.
When i try to use internet via airtel...jio sim show no network. I want this problem to be solved.
Please help me.

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.
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...

Bro i think that volte issue is real in that rom because even developers find issue in it but i haven't tried
I am using le max 2 in India
I am having multiple problems with this phone
First of all I rooted it and installed lineage os on it.
I do not know about the modem version at that time.
Jio Volte was working fine, but sometime jio to jio outgoing call not worked.
Also fingerprint was useless.
After that I installed cn26s modem
With that fingerprint was working and response was good.
But volte incoming calls was not working. (Always out of coverage area.)
Only outgoing and data was working. Also jio to jio outgoing was working fine.
Then I installed developer466d
Same problem as cn26
Then I installed Indian 19s
No luck same as cn26
After that I installed Indian 17s
Fingerprint stop working.
Volte worked but sometime.
I have no idea how to fix volte
Now I downloading 19s full firmware.
If any one have any clue
Here is the link to all modem
https://yadi.sk/d/woKdrlRrv8yhr/
I just flashed full firmware yesterday indian 19s.
Just after flashing only outgoing was working.
Then I leaved the device as it is with 19s.
In the morning incoming started to work itself.
I also noticed same behaviour with other ROMs
Leaving the phone with rom installed and sim installed for few hours worked.
