FAQ

United Kingdom eSIM — Frequently Asked Questions

Does eSIM work in the UK? +
Yes. The UK has top-tier eSIM coverage on EE, Vodafone and O2 with 5G in London, Manchester, Birmingham, Glasgow and Edinburgh, and strong 4G across England, Scotland and Wales.
Does a UK eSIM work on the London Underground? +
The Tube is rolling out mobile coverage station by station — many central lines now have signal on platforms and tunnels, and all Underground stations have connectivity in the ticket halls.
Is the UK included in Europe eSIM plans? +
Since Brexit some Europe plans exclude the UK, so pick a plan that explicitly lists the United Kingdom (or Great Britain) if England, Scotland or Wales is on your itinerary.
How much data for a London trip? +
5GB covers a long weekend of maps, tickets and social media. Choose 10GB+ for a week or if you stream and video call while exploring.
Will my UK eSIM work in Scotland and the Highlands? +
Cities and main roads are well covered by EE and Vodafone; remote Highlands, islands and hiking areas can have gaps, so download offline maps for the wilder routes.
