Astaroam eSIM Data Plans for Costa Rica

Astaroam does not provide an unlimited data eSIM plan for Costa Rica. Instead, the provider offers fixed‑data options, such as the Costa Rica 10GB 30 days plan at $26.08 USD and the Costa Rica 5GB 30 days plan for $18.49 USD. These plans deliver a set amount of high‑speed data, which can be more cost‑effective for most travelers unless they require a very high data volume.

Astaroam does not offer a Costa Rica eSIM plan that supplies a local phone number or SMS capability. The provider sells only data‑only plans for travelers in Costa Rica.

Travelers can use VoIP services such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages.

Astaroam offers a total of ten plans that include coverage in Costa Rica, divided evenly between single‑country and multi‑country options. Specifically, five plans cover only Costa Rica while another five are valid for multiple countries. The available plans feature data caps ranging from 1 GB to 10 GB, with prices that span from approximately $4.14 to $80.55 USD and validity periods between 7 and 30 days. All of the plans are based on a fixed data amount and allow tethering.
