That's where the albeit fairly rare dual-SIM phone has a role.

Only, for some reason, rare in the UK.

The reason is obvious: so many phones are either SIM-locked to one
provider, or are fitted with SIMs on non-rollover tariffs, that the
opportunities for fitting a second true-Pay-as-you-go SIM are quite
limited.

Of course back when 2G phones first came out the SIM was on a card you
could
switch cards easily in seconds but presumably that was deemed too
convenient

I'm not sure how many phones ever took the full size SIM.

Commercial considerations killed them off: the idea was that a person
would have a SIM, and be able to share/borrow a phone to use it in.

But the networks wanted to tie people into having their own phone (and
contract) in particular not wanting a phone they'd subsidised being used
with a SIM from a rival network,

They solved that problem by having phones "network" locked

My "acquired" smart phone still is

Is still what. Locked? That's hardly unusual.

I know

but you seemed not to understand it as the solution to people "sharing"
phones by swapping SIMs in/out

Do keep up: "[Opportunities open up] Even on a locked phone because
(for example) GiffGaff and Tesco both use O2, and Virgin/Orange/T-Mobile
all share EE."

O2 locking also seems to die eventually by around 18-24 months but it
might depend on whether or not a 'phone was originally purchased
outright.
