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
