Plan your connection
Choosing an eSIM in the United Kingdom
Use your itinerary, time away from Wi-Fi and selected plan terms to compare the available options.
Use current transport information during a London stay
Transport for London’s TfL Go app provides route planning, live arrivals and disruption information. Set up your preferred travel tools before departure and save the hotel address and first transfer for arrival.
If London is only part of your visit, include the onward days elsewhere in the United Kingdom when choosing validity. Download essential journey details so a connection interruption does not leave your itinerary inaccessible.
Check UK inclusion on a wider European trip
A Europe plan’s name is not enough to establish that the United Kingdom is included. Compare the exact covered countries if your itinerary also visits France, Spain or another destination.
Compare allowance and validity for the whole trip, then check any hotspot or daily high-speed limits if you expect to work while away. Use the live offers above for current terms and prices.

Common questions
United Kingdom eSIM FAQs
Will a United Kingdom eSIM work on countryside rail routes?
Coverage can be intermittent outside cities and inside trains or tunnels. Save tickets and important directions before beginning the journey.
Should I choose a UK-only plan or a Europe plan?
Choose a local plan for a UK-focused itinerary. For onward European travel, compare regional coverage carefully and confirm the United Kingdom and every other stop are included.
What device do I need to use this eSIM?
You need a carrier-unlocked phone or tablet with eSIM support. Check the exact model and regional variant before buying because eSIM availability can differ between versions of the same device.
Does the eSIM include calls or SMS?
FlyoSIM travel plans are data-only unless the selected plan explicitly states otherwise. You can use data-based calling and messaging apps while connected.
