Good to know before you go to United Kingdom
The UK has near-universal, reliable signal in London and the other major cities, getting even faster in city centers. Coverage is reliably good along the rail network too, which matters if your trip is London-day-trips style (Oxford, Bath, Edinburgh by train). It does drop off in the Scottish Highlands, the Lake District, and parts of rural Wales, so download offline maps before a countryside hike. Most short UK trips are light on data — 2-3GB a week covers maps, messaging, and browsing comfortably unless you are streaming a lot of video on the move.
