TailSim does not provide an unlimited data eSIM plan for Costa Rica. Instead, the provider offers a selection of fixed data plans with caps ranging from 1 GB to 20 GB and validity windows between 7 days and 30 days. For example, a 20 GB plan for 30 days costs $49.99 USD, while a 10 GB plan for 30 days is priced at $26.99 USD. These fixed‑data options can be more cost effective for most travelers unless selecting a very heavy data consumer.
