Best eSIM for the United Kingdom(2026) — connected before baggage claim
Land at London Heathrow, tap the install link from your email—your phone sets the eSIM up itself—and you're online before you clear border control. From there, data does the heavy lifting: Citymapper plots your Tube route into the city, Google Maps walks you to your hotel, live boards tell you which platform your train to Edinburgh leaves from, and WhatsApp lets everyone at home know you've arrived.

Staying connected in the United Kingdom
Practical advice for using mobile data in the United Kingdom.
Enable your eSIM before landing
Install your eSIM at home, then switch its data line on when you land at Heathrow or Gatwick. You're connected before passport control—no airport Wi-Fi forms.
Ride the Tube with Citymapper
Citymapper is the app Londoners use for the Underground: line status, the fastest interchange, where to stand on the platform. Load your route before heading down the escalators.
Download offline maps for Scotland
Heading to the Highlands or the Isle of Skye? Signal fades in remote glens, so save offline Google Maps areas while you're still in Glasgow or Inverness.
Watch live train departure boards
British stations often announce platforms minutes before departure. At hubs like King's Cross or Paddington, watch the live boards on your phone so you're ready when your platform appears.
Hotspot the whole family
On the long train to Edinburgh or a drive through Cornwall, turn on your phone's hotspot and share your eSIM data with the group's tablets and laptops.
