ZenSim does not provide a truly unlimited data eSIM for Greenland. All of its plans have a hard data cap, and the only plan that uses the word "Unlimited" in its name is a 3 GB/day bundle that drops to a throttled speed once the limit is reached.
Travelers who need more data can choose from ZenSim’s fixed‑data plans, such as the 10 GB 30‑day option or the 5 GB 15‑day option, which offer a larger amount of high‑speed data for a set validity period. These plans can be more cost‑effective for most users, while heavy data‑consumers may prefer a fixed bundle that matches their usage.
