Voyasim does not offer an Iceland eSIM plan that includes a phone number or SMS capability. Travelers can only purchase data‑only plans from this provider for Iceland. While this means no traditional voice or SMS service, popular VoIP applications such as WhatsApp, Telegram, and iMessage can usually be used over the data connection for calls and messaging. However, some destinations may block or restrict these apps, so travelers should verify that the services they need are accessible in Iceland before making a purchase.
