Swisscom 3G network shut down end of 2025; Sunrise 3G shut down mid-2025. Many alpine valleys and railway tunnels have no service from any operator. n258 (26 GHz mmWave) is deployed by Swisscom and Sunrise but rarely supported by foreign phones.
The Switzerland mobile network source is linked below as a public network reference. Check the places on your itinerary where the source offers local detail, then confirm the network information for the selected eSIM product. The operator table on this page provides the country-level reference, while the selected product details identify which network information applies to your plan.
Check your accommodation and the places you expect to visit in Switzerland. Indoor reception can differ from an outdoor map, so keep the property Wi-Fi details available as well.
Review the full route rather than checking only the arrival city. Save tickets, addresses and maps offline before longer road or rail journeys.
Check the selected product scope for every country on your itinerary. Your Switzerland plan and a regional plan may have different included destinations and validity periods.
Compare your phone with 4G bands B1, B3, B7, B8, B20, B28, B32 and 5G bands n1, n3, n7, n28, n78, n258 in the existing Switzerland network table. Support for more of the listed bands gives the phone more options when connecting, while the selected product, location and local network conditions determine the service available.
Keep the QR code and installation instructions available offline, and complete each step according to the selected product's instructions.
When validity starts: Validity-start rules can differ by product. Check the selected plan details before installation and travel.
Switzerland offers a mix of alpine adventure and city culture. In the Swiss Alps, hiking trails range from easy lakeside walks to multi-day treks. The Matterhorn region near Zermatt provides year-round glacier views. Lake Geneva’s shores are ideal for relaxed boat trips and vineyard visits. Zurich and Bern combine medieval old towns with modern museums and shopping. Keep a Swiss Travel Pass handy for unlimited train, bus, and boat travel, plus free entry to many museums. Trains are punctual and scenic, especially the Glacier Express route. For winter sports, book ski passes in advance during peak December to March.
Choose from these standout destinations:
Many attractions get crowded in July and August. Arrive early or book timed tickets online.
Swiss cuisine is hearty and cheese-heavy. Must-try dishes include:
Portions are generous. Tap water is safe to drink, and many restaurants offer a fixed-price lunch menu.
Summer (June to September) brings warm weather, clear trails, and lively festivals. Hiking and lake swimming are at their best, but accommodation prices peak. Winter (December to March) is ideal for skiing and snowboarding in resorts like Verbier, St. Moritz, and Zermatt. Snow conditions are reliable above 1,500 meters. Spring (April to May) and autumn (October to November) are quieter and cheaper. Trails may be muddy or closed due to snow. Many mountain lifts close for maintenance in late spring and late autumn. For fewer crowds and lower costs, plan a trip in early June or late September.
Switzerland’s weather changes quickly. Pack these items:
Pack a reusable water bottle; tap water is excellent everywhere. Leave expensive jewelry at home.
