Saily’s UK eSIM starts at $4.49 for 1 GB. For about a week, the 5 GB plan ($12.99) covers maps, rides and messaging.
The catch: plans are data only, so you get no local phone number for calls or texts.
UK trips often start in London and add Edinburgh, the Lake District or Cornwall by train. A UK eSIM keeps Tube routes, train times and maps on your phone from Heathrow onwards.
