Switzerland's three networks — Swisscom, Sunrise, and Salt — deliver genuinely excellent coverage across the Alps, the Plateau, and the Italian-speaking Ticino region. 5G is live in Zürich, Geneva, Bern, Basel, and Lausanne, and 4G/LTE reaches most ski resorts and mountain passes. A Switzerland eSIM activates at Zürich (ZRH) or Geneva (GVA) and keeps you online on the Glacier Express, in Zermatt's car-free streets, and at the top of the Jungfraujoch.
Best time to visit: June–September (summer) or December–March (ski)
