eSIMatrix does not provide an Iceland eSIM that includes a phone number or SMS capability. The provider sells only data‑only plans for Iceland, so travelers will not have an active mobile number or the ability to send or receive text messages with the local operator. However, VoIP applications such as WhatsApp, Telegram, or iMessage can usually be used over the data connection for voice and text communication. Travelers should confirm that these apps are accessible in Iceland before purchasing, as some destinations may restrict or block specific services.
