aloSIM does not provide a plan for Iceland that includes a phone number or SMS capability. All avalable aloSIM eSIMs for Iceland are data‑only.
Without a local number travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages. 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 Iceland before purchasing an eSIM.
