MobiMatter does not offer an eSIM for Switzerland that provides a local phone number or SMS capability. Travelers using MobiMatter will receive a purely data‑only plan that can be used with 4G, 5G, or 3G networks depending on the plan chosen.
For voice and messaging, users can rely on VoIP applications such as WhatsApp, Telegram, iMessage, or similar services over the data connection. However, access to these apps is not guaranteed in every scenario, so travelers should confirm that the services they need are available in Switzerland before purchasing a plan.
