To clear up any confusion, I did some reaarch

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 phone (galaxy A3) (and others to judge by the research) tends to hang
on to the mobile signal rather than use the wifi when it can.
When the signal drops the phone will open UDP connections to ports 500
and 4500 - these can be seen as NAT sessions on my router - and a 'wifi
calling' icon should appear in the phones notfication area depending on
the phone and the version of android etc.

So long as these NAT sessions are open the phone can send and receive
calls and SMS messages over the internet.

The other thing I learnt from the research is the tech support at most
mobile phone companies is worse thanh used toilet paper.

Nearly all wifi calling problems were solved on the fira by other users,
not tech support personnel

If you tell a lie big enough and keep repeating it, people will
eventually come to believe it. The lie can be maintained only for such
time as the State can shield the people from the political, economic
and/or military consequences of the lie. It thus becomes vitally
important for the State to use all of its powers to repress dissent, for
the truth is the mortal enemy of the lie, and thus by extension, the
truth is the greatest enemy of the State.

(c) When the SIM provisioning allows it

previously my phone was on Tesco (O2 mvno) and I couldn't even enable
wifi calling, now it's on Virgin (EE mvno) and I can enable it, but it
still won't work as virgin don't support it.

When the signal drops the phone will open UDP connections to ports 500
and 4500

Also IP protocol 50 (ESP, neither TCP or UDP) those are the same three
connections that femtocells use to create IPSEC tunnels back to the
provider.

It would be strange if they used different...

Yep, but some people seem to think wifi calling uses SIP+RTP because
android phones can do that as well if you configure a VoIP provider.

I forgot to say that AFAIK in the UK only EE/BT ID moble O2 Sky and
vodafone support it on plan, amd only 3 Mobile on PAYG and plan.

My Pixel 3a states "WiFi preferred" under the setting for switching
WiFi calling on or off. It does seem to select WiFi whenever it
reasonably can be expected to. I use EE SIM-only.

I can only guarantee wifi calling here by going into airplane mode and
re-enabling wifi. Otherwise it drops in and out of 3G

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

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.

Well if you turn it on it will work

Its probably not useful at your home, but it IS useful for foreign
travel where e.g. you have acess to airport or hotel wifi, but dont want
to incur roaming charges. Go 'airplane mode' and turn wifi on.

€œit should be clear by now to everyone that activist environmentalism
(or environmental activism) is becoming a general ideology about humans,
about their freedom, about the relationship between the individual and
the state, and about the manipulation of people under the guise of a
'noble' idea. It is not an honest pursuit of 'sustainable development,'
a matter of elementary environmental protection, or a search for
rational mechanisms designed to achieve a healthy environment. Yet
things do occur that make you shake your head and remind yourself that
you live neither in Joseph Stalins Communist era, nor in the Orwellian
utopia of 1984.€�

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

From what I read on the EE web page, it doesn't work when roaming..
Any idea why?

Perhaps they don't want it to work. Outside the EU they must make
a lot of money from call charges.

To make you spend more money?

It certainly works away from home!
