Viasimo does not provide a truly unlimited data eSIM for Costa Rica. The plans labeled “Unlimited” give 2GB of high‑speed data per day; after that limit the speed is reduced (to 512 Kbps for the Costa Rica‑only version, to 384 Kbps for the global version, and to 1 Mbps for the South America bundle). These are fixed data plans rather than unlimited ones.
If a larger data allowance is desired, Viasimo offers fixed data bundles with higher caps. For example, the Costa Rica eSIM, 20 GB, 30 days plan delivers 20 GB of data for a month, and the Global eSIM, 20 GB, 90 days plan provides 20 GB over three months. These fixed plans can be more cost‑effective for travelers who need a larger quantity of data without the daily throttling that applies to the “Unlimited” plans.
