- Keep your WhatsApp active while adding a Swiss data line.
- Pick flexible plans depending on your length of stay or alpine travel.

Coverage & 5G in Switzerland
Switzerland has some of the strongest coverage in Europe:
- Swisscom — #1 in coverage, best speeds across the Alps and villages.
- Sunrise — excellent in Zurich, Geneva, Basel, Interlaken.
- Salt — solid in cities, a bit weaker in remote alpine valleys.
5G: Available in most major cities and even ski resorts (Zermatt, St. Moritz, Jungfrau). On remote mountain trails, expect fallback to 4G or slower.
Transport connectivity
Swiss trains (Zurich–Lucerne, Geneva–Interlaken, Glacier Express) maintain strong coverage, even in tunnels. Ferries on Lake Geneva and Lake Lucerne generally keep 4G signal. Mountain cable cars have patchy service—download maps before heading up.
