What matters here

- TfL publishes Tube coverage by line and section; station Wi-Fi and mobile data are different services.
- Save the hotel address and onward ticket before an underground journey.

FAQs
Will I have data throughout a Tube journey?
Check TfL’s current section list. It lists coverage on the whole Elizabeth line and specified parts of other lines, with rollout continuing. That does not establish uninterrupted access on every route or through every roaming product.
Does a Europe eSIM always include the UK?
Only the purchased product’s country list answers that. The European Commission says EU roaming rules no longer oblige operators to include the UK, although some choose to. A travel bundle’s “Europe” name is not its coverage contract.
