Anyone got LOS 16.0 + Three UK + native WiFi calling working?

Poor us who bought our phones right out. I wonder if this is the case for newer phones too.

There must be someway to get that zip!

I'm looking now to see if there's a download of any official Three ROM packages. Could be fruitless, but worth a look.

Edit: Here's an official Galaxy S9 Three UK ROM download:

Presumably it would have working VoWifi. Now we just need someone to reverse engineer the Telephony settings!
