The Natural Philosopher expressed precisely :
WiFi Calling will activate on phines that support it and mobile networks
that support it when
(a) there is an adequate wifi signal
(b) the mobile signal strength drops below a given level.

My Iphone supports it, but is there any point in my turning it on??

Depends on how often you don't have an adequate mobile signal.

I have fibre wifi at home, which my Iphone is connected to. I use a
Plusnet (EE) for my mobile, on a 3Gb, unlimited calls, unlimited texts
contact and a good EE signal at home.
