£110 a month for 100 GB is actually less than I would have expected for a really remote place like the Falklands. As a point of comparison, I used to pay something like 10 USD per GB on flexiroam while traveling, though I think it's a bit less nowadays. Now that's what I call extortion. And it's still 100 times less than the roaming data rate on my standard mobile subscription.

As for Starlink, keep in mind that you are piggybacking on a humongous satellite network that has tons of unused capacity in remote areas. Now that it's available, it's cool to have it, but the previous provider had an exclusive contract for a reason. And presumably it's still binding, so I imagine the Falklands government is in a bit of a bind over this.

And by the way, Starlink itself is not above price gouging where they have no cheaper alternatives. Look at Starlink Marine pricing for example, which is I think 2500 USD / mo, down from 10000. So there is no actual guarantee that £60 per month unlimited usage will still be be there if Starlink is allowed to operate officially.
