Billion Connect does not provide an unlimited data eSIM for Costa Rica. The plans it offers are fixed data plans, each with a set amount of data that must be used within a specified validity period. For example, the Orange World eSIM 1 Day 100GB supplies 100GB for one day, and the Costa Rica eSIM 30 Days 50GB gives 50GB for thirty days. Choosing a fixed data plan can be more cost‑effective for most travelers unless one is an extremely heavy data consumer.
