Yes, unbelievably so! Switzerland has the best mountain coverage in the world. Our eSIM connects to premium networks (like Swisscom/Sunrise) that provide high-speed 4G/5G coverage in all major tourist towns like Interlaken, Grindelwald, Zermatt, and even at the top of most mountains, including the Jungfraujoch (Top of Europe) and Matterhorn Glacier Paradise.
