Wifi CAlling

[AC Question]

I have a LG V20 Dual Sim phone and with the new update can't seem to find how to turn on the WiFi calling.

The phone is the unlocked version

Which version of android?
Which carrier?

In android 6.x, not all phones supported it and not all carriers supported it.
Did your phone have it before you did the update?
