We will have rental car so planned to get regular Starlink but this one will be much better option.
I respectfully beg to differ. There are massive chunks of Scotland which have no cellular reception at all. There are many places where there is service from some-but-not-all providers. Of those places, there are a few where the service is glacial in performance.
Example: if you stop at The Green Welly Stop in Tyndrum (FK20 8RY), you'll have coverage from only two of the mobile networks. Vodafone and o2 have a coverage patch there. Have a look at the coverage maps (bidb.uk aggregates them all). It's absolutely patchy, and certainly not contiguous.
(1) I'm looking at you Germany, where my connection between Hamburg and Berlin was mostly edge and my LTE connections in the cities were barely useable. I even switched local SIMs from T-mobile to Vodafone because it was so terrible, but was the same result.
As a reference, I have a 20eur/month pay as you go plan from Free (France) that gets me unlimited 5G, calls, messages in France, and unlimited calls and messages + 30GB internet in the whole of the EU + a bunch of other countries. Cheaper, more reliable, more useful, faster.
Also anyone can buy and activate Free esim outside of France.
Dunno if providers will pick up on me teleporting around.
Maybe the better way is some kind of 700mhz repeater-over-IP.
Hotel wifi is 50/50 - sometimes works, some times does not regardless of the price. I stayed in $400/day Mariott with crappiest wifi imaginable (after paying for Premium internet I got unstable 5MB).
We traveled around Columbia for a month this year, and was able to work from 90% of the places we were in using the hotspot. And we were pretty rural a lot of the time.
