Strange. IDNet runs on the old 3 network and I thought they had killed
that off earlier this year? If there is no 3 then 4G should fall back
to 2G for speech and texts - as indeed many phones do especially if they
do not do VoLTE.

I think Three don't have any 2G fallback any more, do they? Their network has only ever had 3G and up. Presumably ID is the same? In which case 'the end of 3G' likely also means the end of calls for 4G phones which don't support VoLTE.

Er, given that 3 and VF are now one, would it be unreasonable to think
that they may fall back onto VF 2G - which AFAIK is not due to be
switched off until 2030.

I don't know, but I suspect spending money on systems to allow legacy customers to roam onto a legacy network is not going to be top of their priority list?

As mentioned elsewhere in the thread, my phone supports VoLTE with Tesco/
O2.
So it appears to be an incompatibility between my phone and the iDmobile/3 network.
Android 11 is early for good VoLTE support as Android 12 had a major functionality upgrade (I read).
So it looks like a new SIM on another network or a new phone.

I've looked in Settings and 4G calling is supported on the Tesco SIM but
not on the iDmobile SIM.
This suggests that it is the 3 network being unhelpful.
This now gives me the problem of finding a mobile network (apart from
O2) which has a compatible 4G/VoLTE for my phone.
Also how to prove this without having to buy and reject various SIMs.
I could always buy a new phone, I suppose, but I like this one and it
does support VoLTE.

Although I think you've already moved on in your diagnosis, to answer
your question above, if you fire up the Network Cell Info Lite app and
then attempt to make a voice call when on a 4G/LTE connection (showing
on the 'Gauge' tab) you will either see if remain on that 4G connection
else it will roll back to 3G/HDSPA (or worse) having failed to use VoLTE.
Which is what currently happens on my O2 PAYG SIM (as I patiently await
the alleged 'upgrade' to support VoLTE....)

The way to tell for sure is to dial *#*#INFO#*#* and look for the 'VoLTE provisioned' for each SIM. That works even if you don't have suitable signal.

I'm getting VoLTE on my O2 Classic PAYG SIM (Pixel 7 Pro, GrapheneOS). GOS does now have a toggle to force VoLTE provisioning if the network doesn't want to, but I've not enabled that. So it looks like O2 have deployed it,
to Pixels at least. What phone are you using?

It's in a old Nokia which supports VoLTE and wifi calling. Well, it did previously on Three....

The whole 2G/3G/4G/5G plus VoLTE and so on just seems to me to be a
way to force people to update their phones continuously. It's a total
can of worms.

ThatrCOs not entirely correct. Many 10 Gbit switches will not support a 10 Mbit device. In general you get backwards compatibility in technology when the cost of so doing is low.
2G and 3G donrCOt use the radio spectrum as efficiently as 4/5G. Spectrum is scarce, so itrCOs not sensible to support the older technologies in the long term.
The way to tell for sure is to dial *#*#INFO#*#*

I find it very difficult to plug a 50+- BNC connector into a 8P8C socket (not to mention N connectors and vampire taps).-a (8P8C is the correct
name for what is popularly called RJ-45.)
