Most EU and Europe eSIMs do not include Switzerland in their main roaming zone, or include it with reduced data allowances and higher fees. Switzerland is part of the Schengen Area but not the EU, so EU roaming rules don't apply. Travelers are often surprised by extra charges or limited data when crossing into Switzerland on a Europe eSIM. The ETravelSim Switzerland eSIM is purpose-built for Switzerland on Swisscom's network, with predictable pricing and full data allowance for the country.
