Public Wi-Fi in Europe: a practical safety routine for travellers

Use airport, hotel and café Wi-Fi more safely in Europe with simple checks, safer alternatives and device settings.

Hotel, airport, station, and café Wi-Fi can be convenient for a large download or a quick map refresh. Convenience is not the same as trust. CISA advises against using open public Wi-Fi for personal business, banking, or shopping because attackers may intercept sensitive information; it suggests cellular data rather than an unsecure public wireless connection for sensitive transactions.

Verify the network before joining

Ask staff for the exact network name and connection method. Be wary of nearly identical names, unexpected password prompts, or a sign-in page that asks for more information than seems necessary. Turn off automatic joining for unfamiliar networks so the phone does not reconnect later without your noticing.

A password-protected hotel network is not automatically private. Use the same caution in a lobby as in a coffee shop: avoid opening account settings, sending identity documents, or making financial changes unless you have a connection you trust. Keep the phone, browser, and important apps updated before the trip so known security problems have a better chance of being patched.

Choose the safer connection for the task

Use mobile data for sensitive, time-critical tasks when your travel plan allows. Save open or public Wi-Fi for lower-risk actions such as reading local information, downloading an offline map, or streaming a non-sensitive programme. If you use a reputable VPN, understand what it does and does not do; it does not make a fake login page legitimate or remove the need to check the network name.

CISA also recommends switching Bluetooth off when it is not being used and avoiding charging through an unknown shared computer or charging station. Carry a power bank or use a charging-only setup you control if battery is a concern.

Leave cleanly

When you finish, forget the network if you will not need it again. Check that Wi-Fi is off or that automatic join is disabled before you leave the venue. Review any new certificates, profiles, or apps you were asked to install; remove anything you did not expect. Never let a Wi-Fi captive portal persuade you to install a configuration profile without verifying it through the venue’s official staff or website.

Pair this routine with an arrival-day connection plan and a travel data budget. If Wi-Fi is your only route to eSIM activation, use a trusted hotspot where possible and save provider instructions first.
