That's a population distribution issue, not an area size issue (you yourself raised the size of Texas as a "problem").
FWiW the state I grew up in is 3x the area of Texas with cattle stations larger than those tiny Texas ranches.

If you want to challenge the myth of coverage in Europe forget about size comparisons and look to some of the hard walking trails in remote areas; Via Dinarica Kosovo is known for it's beauty and harsh terrain, not for it's cell reception.
Elsewhere in the Balkans, Romania, et al you'll find blind spots.
The signal in the Kimberley's is shithouse, mate. Last time I was there, I went three days with zero signal, because I was in some more remote communities. That's not really an argument against what I was suggesting, is it?

No, that's pretty much just a tangential straw interpretation of your own design as the signal quality in Kimberley, or lack thereof, has got three tenths of f'all to do with the issue being population distribution rather than size.
Both Europe and the US have low population regions with poor signal.
Upthread I suspect the anecdata about good quality signal in Europe came from somebody who had more exposure to the well trod higher population density parts of Europe and hadn't encounter less covered corners.

The anecdote, was suggesting that our vast and empty lands are trivial to cover. But as you know, that has nothing to do with reality. I'm so sorry I tried to convey it with a tinch of kindness to them. Next time I'll tell them to pull their fucking head in.
