Michael Chare remarked:
Since smart meters aren't standardised and are much more complex
than simply reading the numbers off a variably-shaped box, they
don't want to take responsibility for whatever piece of junk your
past supplier fitted. That includes not wanting to get involved in
whatever connectivity the past supplier arranged - the old supplier
contracted with some mobile network, but the new one won't have any
arrangements set up and would have to re-make them piecewise.

Don't be daft, there are millions of meters and only a dozen or so
mobile networks (assuming you count MVNOs as well). Every energy company
having some sort of deal with every mobile network is trivial in the
grand scheme of things.

So what is your explanation as to why smart meters are linked to one
particular supplier?

Because what they send over the network differs, one from another.
