Gatwick covers the basics — SIM vending machines at baggage claim in both terminals (EE, Three, Lycamobile) and WHSmith stores in the arrival halls (the South Terminal one is 24/7) — though prices run higher than London phone shops. An eSIM still wins on price and lets you skip the machine fumbling after a red-eye.

Getting online at London Gatwick (LGW)
Gatwick leans leisure — arrivals catch trains into London or head to the south coast, where offline maps quickly fall short of a live connection.
Most large airports, including London Gatwick (LGW), offer free terminal Wi-Fi — but that signal ends the moment you step outside to the taxi rank or train, which is exactly when you need maps, ride-hailing and messaging most. Buying a SIM at the counter means queueing after a long flight, showing your passport for registration, choosing from a short menu of tourist bundles, and swapping out your physical SIM so your home number goes offline. None of that is terrible — but all of it is avoidable.
How to be online before you leave the jet bridge
- Before you fly: pick a United Kingdom eSIM above and buy it — you'll get a QR code by email in minutes.
- Install it on home Wi-Fi: scan the QR in your phone's cellular settings. Leave the line switched off for now; your home SIM stays your default.
- When you land at London Gatwick (LGW): turn off airplane mode, enable the travel eSIM's data line, and turn on data roaming for that line. It connects to a local network automatically.
- Walk out connected: maps, ride-hailing and messaging all work before you reach the taxi rank — no kiosk, no queue, no passport photocopy.
