Any question answered...

I still want to use the dingle so can't cut the sim down to hodge into the iPad. I have a decent monthly allowance for Internet but can't get it unless the supplier can give a vat receipt. I might have to go into the shop and face sales talk!

I cut it down in the way I was able to put it back together with some sellotape.

As for the tariffs, can't help you at the moment, as it all changed since the last time I did the research.
