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.
