Will my eSIM work as soon as I land in United Kingdom?

Yes — install it at home on Wi-Fi before you fly, then switch the line on when you land. It joins a partner network in United Kingdom automatically, usually before you reach baggage claim. Your days only start counting at that first connection.

Do I keep my own number and WhatsApp in United Kingdom?

Yes. This is a data-only eSIM that runs alongside your home SIM. Your number stays active for calls and texts, and WhatsApp keeps working on your usual number the whole trip.

When do my days start counting?

Only when the eSIM first connects to a network in United Kingdom — not when you buy or install it. Buying ahead of your trip is completely safe.

Which phones work with a United Kingdom eSIM?

Most phones from 2018 onward: iPhone XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, plus many recent Xiaomi, Oppo and Motorola models. Your phone must also be carrier-unlocked — check yours in 30 seconds on our compatibility page.

What makes an eSIM the best choice for United Kingdom?

Three things decide it: a price agreed before you fly, data that doesn't run out mid-trip, and a setup you can finish at home. A prepaid unlimited travel eSIM answers all three — from £1.88 per day in United Kingdom, with the QR code in your inbox seconds after ordering.

Visiting more than one European country? The Europe regional eSIM border-hops automatically on a single plan.
