Sony Xperia Z3+ dual support for VoLTE and Reliance Jio 4G

I have my Sony Xperia Z3+ dual and I love this phone. But I plan to use Reliance Jio when it is launched because I have used its on friend's samsung phone and its speed are very good and its pretty fun to use at such high speed 4G internet. Does my phone support full 4G offer by Reliance including VoLTE feature ?

This is 4G band support for my phone , there are so many of them.
LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 12(700), 17(700), 20(800), 38(2600), 39(1900), 40(2300), 41(2500)

How I to know which one is for reliance 4G and not even sure about VOLTE support.

Do you see this in your phone :

Menu > Settings > Call Settings > Enable VoLTE

If its there then yes, your phone has VOLTE support .

For Reliance JIO 4G support, it has support for all bands used by RJIO, ie.
Band 5 (850 MHz)
Band 3 (1800 MHz)
Band 40 (2300MHz)

So we can say its RJIO compatible.
