eSIMsData does not provide a true unlimited data eSIM for Costa Rica. The plans listed as “Unlimited” only allow a set high‑speed allowance each day—1 GB/day or 2 GB/day—and, after that cap is reached, the speed is throttled to 1250 kbps or 2000 kbps. A genuinely unlimited plan, with no data cap or speed reduction, is not offered.
Travelers who need large data volumes can choose fixed data plans instead, such as the 100 GB 30 days plan for $73.44 USD or the 50 GB 30 days plan for $43.39 USD. These plans provide a large, hard limit of high‑speed data and can be more cost‑effective for high‑usage users.
