United Kingdom eSIM: daily caps, throttling and hotspot, brand by brand
Of 24 travel eSIM brands with a rule that applies to United Kingdom, 10 publish a daily full-speed allowance, 9 publish the speed you drop to afterwards and 5 state a hotspot rule (1 block hotspot outright). 3 rows rest on dated customer reports rather than the brand's own page and are marked unverified. Every number links to its source with the date it was observed; last review 2026-10-19.
The UK is outside most "EU" roaming arrangements, so travel eSIMs are the usual choice and the brands apply either a UK-specific or a Europe-wide fair-use rule on EE, Vodafone, O2 or Three. London days are data-heavy (contactless transit apps, navigation, maps underground on arrival), which is exactly when a daily bucket runs out. The table shows the published rules.

What to watch for in United Kingdom
Not every Europe plan includes the UK; a UK row here does not mean the regional plan covers it.
Hotspot blocking is common on unlimited UK plans from some brands.
Rail and rural Scotland and Wales expose host-network choice more than the cap.
