Stay Connected in Lausanne

Lausanne's connectivity is excellent, as you'd expect from a Swiss city. Fast 4G/5G runs almost everywhere, fiber sits in most accommodations, and free WiFi covers the train station, the metro, and much of the lakefront. The frustration isn't coverage. It's cost. Switzerland sits outside the EU roaming zone, so European travelers who breeze across borders with their home plans suddenly face per-MB charges that catch people off guard. Travelers from further afield often assume Switzerland follows EU rules and get an unpleasant bill. The other quirk worth noting in Lausanne specifically: the city tumbles down a steep hillside between the cathedral and Lac Léman, and signal can dip briefly inside the metro tunnels and a few of the older stone buildings in the Old Town. Nothing severe. Worth knowing if you're on a video call. Plan ahead and connectivity here is a non-issue.

Three carriers run the show in Switzerland: Swisscom, Sunrise, and Salt. Swisscom has the most extensive coverage and tends to win independent network tests. It's the safe pick if you'll head into the Alps for day trips from Lausanne. Sunrise is competitive on speed in urban areas and often cheaper on prepaid plans. Salt is the budget option. Fine in Lausanne itself. But coverage gets spotty once you leave the main areas. Fair warning. In Lausanne city centre you can expect 5G on all three networks, with download speeds typically in the 200 to 500 Mbps range and 4G fallback that still comfortably handles video calls. The M1 and M2 metro lines have in-tunnel coverage, though it occasionally hiccups between stations. Lake-facing neighborhoods like Ouchy get strong signal across the waterfront. Heading further afield? To the Lavaux vineyards or up to Les Diablerets, Swisscom is noticeably more reliable than Salt.

Free WiFi is everywhere in Lausanne: hotels, the train station, most cafes, the lakefront promenade in Ouchy. It's mostly fine for casual browsing. The risk isn't unique to Switzerland. Public networks let anyone on the same access point potentially intercept unencrypted traffic. Travelers tend to be targets. They check bank apps, booking sites, and work email from unfamiliar networks. A VPN like NordVPN encrypts everything between your device and the internet, so even on a sketchy cafe network your login credentials stay private. Worth using whenever you're doing anything sensitive: banking, work logins, accessing cloud storage. For watching Netflix or reading the news, it matters less. Hotel WiFi in Lausanne is generally well-managed but still shared infrastructure, so the same logic applies.
