Astaroam eSIM Data Plans for Costa Rica

Astaroam does not provide a truly unlimited data eSIM for Costa Rica. The plans that carry the word “Unlimited” in their name give a fixed data allowance of 3 GB per day for the specified number of days, after which the speed is throttled to 1000 kbps.

If you need a larger, fixed amount of high‑speed data, Astaroam offers alternatives such as the Costa Rica 10 GB 30 days plan for $18.16 USD or the Costa Rica 5 GB 30 days plan for $13.94 USD. These are fixed data plans that can be more cost‑effective unless you anticipate using far more data than the daily allotments.

Astaroam does not provide any eSIM plans with a phone number or SMS capability for Costa Rica. Only data‑only eSIMs are offered by the provider for this destination. Travelers who need to make calls or send text messages can use VoIP services such as WhatsApp, Telegram or iMessage over the data connection, but they should verify that those apps are accessible in Costa Rica before purchasing.

Astaroam offers six single‑country plans and twelve multi‑country plans for Costa Rica. The available plans range in price from about $3.26 to $45.71, with data caps between 1 GB and 10 GB and validity periods from 3 to 30 days. Some plans feature a daily data cap while others provide a fixed data amount for the entire validity period.
