iRoamly does not provide an unlimited data eSIM for Central America. All of its Central America plans are fixed data bundles that give 2GB of high‑speed data per day, with validity ranging from 1 day to 10 days. For example, the 2GB‑1‑day plan costs $15.50 USD, while the 2GB‑10‑day plan costs $136.00 USD.
Because the data allowance is limited to a fixed amount per day, these fixed data plans can be more cost‑effective for most travelers, unless the user is an extremely heavy data consumer who would need a truly unlimited plan.
