Skyalo does not provide any eSIM plans for Switzerland that include a phone number or SMS capability. All eSIMs sold by Skyalo for Switzerland are data‑only, meaning users can access high‑speed internet but cannot make or receive standard voice calls or SMS messages.
Travelers who need voice and messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to stay in touch. However, some destinations may block or restrict certain VoIP services, so it is advisable to verify that the apps you rely on are accessible in Switzerland before buying a Skyalo eSIM.
