yaySIM does not offer any eSIM plan for the Åland Islands that includes a phone number or SMS service. The only plans available to travelers are data‑only eSIMs.
With a data‑only plan users can still make calls and send messages through VoIP applications such as WhatsApp, Telegram, and iMessage, as long as those services are accessible in the Åland Islands. Because some destinations may block or restrict certain apps or VoIP services, travelers should verify that the apps they rely on are available before purchasing a plan.
