eSIMCard does not provide a truly unlimited data eSIM for Estonia. Every plan that carries the word “Unlimited” in its name—including “Unlimited Data For 1Day in Estonia, Throttled” and “Unlimited Plus Data For 1Day in Estonia, Throttled”—offers a fixed high‑speed data allowance of 1 GB or 2 GB and, after reaching that cap, the speed drops to a specified kilobit rate. Similar one‑day and multi‑day plans cap data at 1 GB or 2 GB per day, and the plans featuring unlimited minutes still impose these data limits.
For travelers who need a larger data allocation, eSIMCard offers fixed‑data plans instead. Examples include a 50 GB plan for 30 days, a 35 GB plan for 30 days, and a 100 GB plan that lasts 90 days. These plans provide high‑speed data without the throttling applied to the “Unlimited”‑named plans, making them a more cost‑effective choice for heavy data users in Estonia.
