Switzerland's mobile network is served by three main operators: Swisscom, Salt, and Sunrise. 4G LTE coverage is comprehensive across Zurich, Geneva, Basel, Bern, Lucerne, and all major cities, with strong connectivity along main SBB rail routes and motorways. Alpine resort areas including Zermatt, Verbier, Davos, St. Moritz, and Interlaken have reliable coverage in resort and town zones, with signal weakening at high altitude on ski runs, via ferrata routes, and remote alpine trails above 3,000 metres. The Matterhorn, Jungfraujoch, and other high alpine destinations have coverage at their visitor centres and main stations. Switzerland's dense network infrastructure means even many rural and valley areas have reliable connectivity.
