Avelis eSIM does not offer an Icelandic eSIM that provides a local phone number or SMS capability. Travelers can only purchase data‑only plans from this provider for Iceland. They can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging. However, some destinations may block or restrict access to certain apps or VoIP services, so travelers should confirm that these services are available in Iceland before purchasing.
