Where do smart meters get their power from?

As I understand it, it is battery powered half hourly readings from the gas
meter to the smart-enabled electricity meter, and then that handles the
communication of both readings to the supply company fundamentally via a
sim card arrangement.
Correct, except the gas meter updates the electric meter more
frequently than that. Judging by the indoor displays gas consumption
updates, its maybe every couple of minutes.
