4G VoLTE calls confirmed working with carrier x

[Kevin Kofler]

In principle, VoLTE should work. (It works for me, but I am almost at the other end of the world, in Austria (2 letters sure can mean a huge distance geographically), so that confirmation does not help you all that much.) What I know is that for some carriers, VoLTE might only work with a specific modem firmware version or with manual configuration, for most, it will just work. If you need confirmation, you will have to wait for someone who has tried VoLTE on Vodafone Australia to hopefully chime in.

To answer the original post:
In Austria (the one in Europe), carrier: HoT (MVNO on the network of T-Mobile/Magenta), VoLTE just works (since it was enabled late last year – there was previously no carrier support for it).
