ZenSim eSIM Data Plans for Costa Rica

ZenSim does not provide a truly unlimited data eSIM for Costa Rica. Plans named “unlimited” actually allow 3GB of high‑speed data per day; once the daily 3GB cap is reached, the connection speed is reduced, although the exact throttled speed is not listed in the plan details.

Instead, ZenSim offers several fixed‑data options that may better suit most travelers. For example, Costa Rica 20GB for 15 days costs $54, Costa Rica 20GB for 30 days costs $60, and Costa Rica 10GB for 15 days costs $35. These plans provide a large amount of data for a set period and can be more cost‑effective unless a user requires an extremely large data allowance.

ZenSim does not provide an eSIM with a local phone number or SMS capability for Costa Rica. The supplier offers only data‑only eSIM plans for that country. Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages, even without a traditional phone number or SMS service.

ZenSim provides 10 single‑country data plans and 10 multi‑country plans that can be used in Costa Rica. Among these, there are 2 daily‑data‑cap plans that limit usage each day, while the remaining 18 plans offer a fixed total data amount for the entire validity period. Overall, the plans vary from about $6 to $64, with data caps ranging from 1 GB up to 20 GB and validities between 5 and 30 days. Some plans also allow tethering.
