Using mobile data in United Kingdom
Coverage during your trip
Coverage is typically strong across London and other large cities. Reception on the London Underground varies by line and station, and it can be patchy in the Scottish Highlands, the Lake District, Snowdonia, and on rural rail lines, so keep tickets and directions available offline.
Choosing and preparing your plan
Most visitors rely on maps, transport apps, and messaging, which are light on data; video, photo backup, and hotspot use push totals up quickly. Check the coverage list if your trip includes the Republic of Ireland, which is a separate country from Northern Ireland.
United Kingdom eSIM questions
Does a UK eSIM work on the London Underground?
Mobile coverage on the Underground is expanding but still varies by line, station, and tunnel. Download your route or tickets before travelling so you are not relying on a signal between stations.
Does a UK eSIM cover Northern Ireland and the Republic of Ireland?
Northern Ireland is part of the United Kingdom. The Republic of Ireland is a separate country, so check the plan's coverage list or compare a Europe regional plan if you are crossing the border.
How much data do I need for a week in London?
Maps, transport apps, and messaging usually need only a few gigabytes for a week. Add more if you stream video, upload lots of photos, or share a hotspot.
