Zwitchy does not offer any Greenland eSIM plan that provides a phone number or SMS capability. Only data‑only eSIMs are available from this provider for Greenland. Travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and text communication, but they should verify that these services are accessible in Greenland before purchasing, as some destinations may block or restrict certain apps.
