VoLTE Support for Z3

[greatmant]

Is there a chance that the new Marshmallow update for the Z3 will finally add universal VoLTE support for all variants of the Z3 that are LTE? I am frankly getting quite annoyed that many of my colleagues have phones that support VoLTE and get to enjoy a call without switching the entire phone to 3G mode. Note that my carrier has VoLTE support as well.

This support it's network related, contact them regarding this.

I always wonder if it's on the phone manufacturer side to activate/enable volte through system update. It's because my carrier always says their network has been always ready for volte use. Like z3 D6653 is volte-able but z3 dual D6633/D6653 is not. D6653 wasn't able to use volte initially but it's usable after a system update.
I have an additional question: can I use my z3 volte function abroad when I switch to a local sim from a local carrier? Does system update region specific? Is a particular system update just design to enable volte in a particular country?
I believe is the phone manufacturer to decide whether they want a particular phone variant to have the volte function. Not just sony, but others like Samsung, LG. Say, in my country, LG G3 single SIM variant is able to use volte, while it's dual SIM variant is not. But both LG G4 single and dual sim variants can use volte.

The D6603 variant international Xperia Z3 is not VoLTE capable, as far as I remember reading, only the Japanese variant is supporting VoLTE.

D6653 international variant is volte capable. I'm using it. Hardware wise, nearly all newer phones are volte capable. It's just whether the firmware is set to enable it.

Hi @ChandraSekhar0,

Welcome to the community!

If your device supports VoLTE depends on your operator as this is a network based setting. I recommend that you contact your operator regarding this to see if they plan on making this feature available for your device.

@ChandraSekhar0, 

In order for VoLTE to be enabled your phone may have to be branded to an operator that supports it. There is no setting I can refer to in order for you to enable this feature, I can only refer you to contact your operator about this.
