WiFi & Connectivity
Stay connected at EuroAirport Basel–Mulhouse–Freiburg — free WiFi, eSIM options and local data for France.
Airport WiFi at BSL
No registration required — connect and browse immediately.
Because the airport straddles France and Switzerland, roaming coverage is uneven: an EU/France plan covers the French sector cleanly, but Switzerland sits outside the EU, so some EU roaming plans exclude it or apply extra charges even though you're standing in the same terminal — check your specific plan's Switzerland coverage, or bring a separate Swiss/EU-wide eSIM to be safe.
The free wifi (just accept the terms on the portal page, no account needed) generally works well across the whole terminal regardless of which sector you're in, so it's a reasonable fallback while you sort out mobile roaming.
