GigSky does not provide any unlimited data eSIM plan for Greenland.
The available options are fixed‑data plans with caps such as 10GB for 30 days, 20GB for 90 days, 50GB for 180 days, and a 10GB travel package that covers both Greenland and 47 other countries. Choosing a fixed‑data plan can be more cost‑effective for most travelers, though it does limit usage to the specified amount within the validity period.
