This is the most important thing to know before visiting Switzerland. Despite being surrounded by EU countries, Switzerland is not an EU member and is explicitly excluded from EU roaming regulations. If you use a standard European eSIM in Switzerland, you will pay international roaming rates — often €2–€5 per day extra. Ovosim's dedicated Swiss eSIM uses local Swisscom pricing from the moment you cross the border.
Salt has been ranked the world's best mobile network by umlaut and Opensignal multiple times. In practical terms: 5G coverage in every Swiss city, 4G in virtually every Alpine village, and network penetration deep into mountain valleys that would be dead zones on any other country's infrastructure. This is the network your Swiss eSIM connects to.
Swiss ski resorts — Zermatt, Verbier, St. Moritz, Davos, Grindelwald — all have excellent Salt 4G/5G coverage on the slopes, in the gondolas, and at the summit restaurants. The famous Jungfraujoch (Top of Europe, 3,454m) has 4G. The Glacier Express between Zermatt and St. Moritz maintains connectivity through most of the journey, with brief gaps in the deepest Alpine tunnels.
The SBB (Swiss Federal Railways) app is the essential tool for navigating Switzerland's famous public transport network. You need data to check real-time departure boards, book seats on panoramic trains, and validate mobile tickets. Salt's nationwide coverage means you stay connected at every station from Geneva to St. Gallen. Download the SBB app before arriving.
Switzerland is perfectly positioned for day trips into neighbouring countries. Day trips to Lyon (France), Milan (Italy), Munich (Germany), and Innsbruck (Austria) are popular from Swiss bases. Note: your Swiss eSIM covers Switzerland only. If you cross into France, Germany, Italy, or Austria, you will need a separate plan or Europe+ eSIM for those countries.
