Kenzo doesnt support smartfren volte.
Max pro is new phone and it has firmware update for smartfren volte
Try using smart volte app for 4g voice volte app from playstore.

Volte switch need to enabled in EFS partition.
Efs is where our all imei number, mac adress, baseband stuff is stored.
Upgrading to higher android version doesnt give u volte.
So far only jio sim is enabled in india in 2016. After that xiaomi didnt care to push volte for other carrier. They can easily enable it by pushing update. its their way of marketing and forcing customer to buy new phone.

Xperia X VoLTE

Hi guys, here in my city and another ones near recently we have some carriers with VoLTE enabled. I was thinking about reasons that Xperia X don't have VoLTE enabled... I tested in another phones that i have and it works perfectly. The SOC is a snapdragon 650 wich supports VoLTE and HD Voice features, also VoWiFi, according GSMArena it also supports 700MHz band, wich is the one that we have VoLTE here... I'm leting something scape? I also tried some build.prop configs what give-me some "toggles" access "Enable VoLTE" in network settings, i've set to enabled but isn't... So, our stock software don't have any implementation for VoLTE? I've already research about and don't find any satisfactory information...
Thank you,
Luiz
Some providers enable the Volte on the sim only if they see the sim is in a supported phone by them, if its enabled by default on the sim then the phone has to have selected the right modem. You should check to see if sony has specific firmware for your provider here: https://xpericheck.com/device/F5121 , and if it does you should flash the specific firmware if not your only way to make it work is to change some stuff in build..prop and check different modems (you can google to see how its done) and maybe you are in luck that some other provider has the same modem settings with your provider.
1. Check to see if your SIM has Volte enabled on it or you have a way to enable it (some providers auto activate it if they see the sim is in a phone accepted by them and for some you need to send an SMS or something to activate it )
2.Check on xpericheck if there is a specific firmware for your provider (if yes you should flash that , or just flash the customization file) and if not
3. Enable volte in build.prob then test different modems maybe you get lucky (only if you have root)
The phone supports Volte and it works smooth if your provider and sony released a firmware version for it.
I already try to enable VoLTE on build.prop, also searched for modems but no good results. I'm using TIM operator in Brazil on F5122, the only modem for TIM is from another Sony model, and not working yet...

Could unlocked T-Mobile V60 activate LoLTE/Wifi Calling?

Hi XDArs
I have an unlocked T-Mobile V60 thinQ(LM-V600TM), and now I am using it in Taiwan.
But I cannot see the VoLTE option and turn on the WiFi calling.
Any way to solve this? To help me activate these functions.
(like flash ROM, kernel, driver or radio...)
Thanks
Does your Taiwanese carrier provide WiFi calling option?
Hi there,
If you're on A12, then to enable VoLTE, you may root your device and change one line in the build.prop:
ro.vendor.lge.build.target_operator=SW
Then you may not see the VoLTE toggle but VoLTE should be enabled.
