eSIMatrix does not provide an unlimited data eSIM for Costa Rica. Instead, the provider offers fixed‑data plans that cover the country. For example, the “South America 20 GB – 5 days” plan includes 20 GB of high‑speed data for five days and is valid in Costa Rica as well as 16 other South American countries. The same 20 GB data amount is available for 10 days and 15 days, with prices ranging from $70.00 USD to $82.00 USD. Choosing a large fixed data plan can be more cost‑effective for most travelers unless they require truly unlimited usage.
