Esim in the uk ...

Hi,

I ordered a physical sim (one-off monthly "contract") for my dual sim phone so that I can set Smarty as the data side, and back up calls side (different network) while off away in the camper.

It has not arrived and I'm due to travel tomorrow.

Do I have the option to "replace" it with an esim?

If so I don't see a way in to do that :-/

Anyone had the same issue?

TIA ...
