Xperia devices don't bring IMS/RCS settins for all regions/carriers in one. So to have VoLTE in your region your device has to be manufactured for your specific region. Alternatively you may install firmware for your region, but there is no an official way to do so. Look for an unofficial way on XDA. I was able to reflash my device this way to have VoLTE in my region. Also make sure that XZP is in your carrier's list of VoLTE-capable devices.

Here network is jio which supports volte. When inserted sim it should show volte but it doesn't where as in other mobiles it does. Cause of not volte we should use jio app for making calls. If there is volte there is no need of app for making calls
Yes it supports volte. Could you please gimme the link to flash the firmware to India.

Xz premium has volte. I bought it and I updated it to oreo. it was so cool. The problem was that I couldn't use volte. So I flashed it to Indian firmware. Still, there was no volte. I regret it. I just found that the problem was with my jio sim. I inserted my friend's jio sim and I the wonder. I could use volte feature with his sim. I inserted my sim in his volte supported phone and it was the same for him. There was no problem. There are some jio sim cards that doesn't support volte lurking around everywhere I guess. I recommend you to insert someone else's volte sim card and test it. You can have sim replacement from jio's customer service centers.

Hi @Sajujacob, welcome to the community.
VoLTE is controlled by the network, but the XZ Premium does indeed support it. Your network may need to push an update to your handset to use it though.
I recommend you contact your network and ask if they support VoLTE on this handset.
Are there any plans to get support for VoLTE/Wifi Calling on XZ Premium on T-Mobile as there is on the XZ1/XZ1C? It seems silly that what are functionally the same devices (besides screen resolution/size) cannot both have VoLTE certification.

But I am a bit scared to try it out. It would be great if you could share the process or could confirm that you followed the similar steps as mentioned here Flashing XZP
