eSIMCard does not provide a truly unlimited data eSIM for Costa Rica. All plans that use the word “Unlimited” in their name actually include a fixed data allowance—such as 1 GB/day or 2 GB/day—after which the speed is throttled to a lower rate (for example, 500 kbps or 2000 kbps). Therefore, there is no plan that offers high‑speed data without any limits for travelers in Costa Rica.
For travelers looking for larger data volumes, eSIMCard offers several fixed‑data options. A 100 GB plan valid for 180 days is available for Costa Rica, as is a 50 GB plan that lasts 30 days. These plans provide a set amount of high‑speed data and may be more cost‑effective for users who need substantial bandwidth without the continuous limits of the “Unlimited” packages.
