Just waiting for Three UK to release the Marshmallow update for the Z5.
I have installed the Z5 O2 UK software and under settings no VoLTE option as this network does not support, however in the #*#*#4636#*#* settings shows the VoLTE provisioned flag is on, so maybe this means the software is enabled now for it and we just need to have a supported carrier.
I will put the software on and use Three SIM card and report back when I have tested.

Does anyone know if the E6883 will be able to use VoLTE on three.co.uk network?
I know that it I would have to be in VoLTE enabled area (Central London), but does the setting for VoLTE need to come from three.co.uk in order for it to work, or does it come from Sony?
Is the VoLTE only between VoLTE handsets?

I have been doing some research and testing lately with my Xperia Z5 (E6653) running the latest Three UK firmware build: 32.1.A.1.163-R4C on the Three UK network SIM.
Here are my findings:
Currently I can see 2 clear ways to enable VoLTE.
Hope this helps.
I have now moved to EE and as another point of interest, although I have not purchased the phone from them, I have also flashed the EE firmware to the handset, and I am able to use WiFi calling with a SIM only plan, which is contradicting to what the networks are actually informing people.
This seems more or less like announcing new network features and advanced technology to improve coverage, but in the process, deliberately trying to lock people out who do not only pay for network access but also the phone from the network.

From what I can see the Xperia Z5 Premium Dual SIM is not a phone that can be purchased or gained on contract and also from checking XperiCheck.com no carrier firmware is available.
