United Kingdom travel eSIM comparison
UK eSIMs ride EE, O2, Vodafone or Three. Two local facts matter: London Underground platforms now have data coverage on most lines, and UK networks no longer include EU roaming after Brexit — so if your trip continues to Europe, choose a bundle that covers both.
Cheapest right now: Airalo UK · 1GB · 3 days at HK$31.79 per month.

FAQs
Will my eSIM work on the Tube?
Increasingly yes — most central stations and many suburban platforms across all lines now have mobile data. Deep sections of some lines still drop out between stations.
I'm visiting Paris after London — what should I pick?
Pick a Europe-region bundle that explicitly lists both the UK and France rather than a UK-only plan. Check the country list: most "Europe" bundles cover the Schengen area plus the UK, but Switzerland/Turkey are not always included.
