Astaroam eSIM Data Plans for Costa Rica

Astaroam does not offer a truly unlimited high‑speed data eSIM for Costa Rica. The plans labeled “Unlimited – 3 days, 5 days, 7 days, 10 days” give 3 GB of high‑speed data per day and, once that daily allotment is used, the speed drops to 1000 kbps. Users looking for more generous high‑speed data can consider Astaroam’s fixed‑data plans, such as the 20 GB plan valid for 30 days at $25.20 USD and the 10 GB plan valid for 30 days at $16.17 USD, both of which include tethering. While fixed data plans may cost more if you need a lot of data, they avoid the throttling that applies to the “Unlimited” options and can be more cost‑effective for heavy data users.

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 a mix of single‑country and multi‑country data plans that include coverage in Costa Rica. In total, there are six single‑country plans specifically for Costa Rica and fifteen multi‑country plans that list Costa Rica among other destinations. The available plans span a price range of about $3.21 to $44.97 and data caps from 1 GB up to 20 GB, with options that either allocate a fixed amount of data for the entire validity period or cap the amount of data that can be used each day. These plans also support tethering at reduced speed, with a limit of 1000 kbps in applicable cases.
