Stellar eSim does not offer an Iceland eSIM plan with a phone number or SMS capability. Only data‑only eSIM plans are available for Iceland, so travelers cannot make regular phone calls or send text messages directly through the network. They can, however, use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging, but some destinations may block or restrict these services. Travelers should verify that the VoIP apps they rely on are accessible in Iceland before purchasing.
