Saily eSIM Data Plans for Belgium

Saily does not provide a truly unlimited data eSIM for Belgium; the plans that carry “UNLIMITED” in the name offer a 5GB/day cap. After the daily limit is reached, the data speed is reduced to 1024kbps.

Travelers can choose from fixed‑data alternatives that may be more economical for most users. For example, Saily sells a Belgium 20GB 30‑day plan for $26.99 USD and a Belgium 10GB 30‑day plan for $17.99 USD, both offering high‑speed data without daily caps. These plans give travelers the flexibility to use a large amount of data with predictable costs.

Saily does not provide any Belgium eSIM plan that includes a local phone number or SMS service. The company offers only data‑only eSIMs for travelers visiting Belgium.

Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, as these services do not require a physical phone number or SMS capability.

Saily offers 10 single‑country data plans and 16 multi‑country data plans that are valid for travel to Belgium. The available plans cover a price range of $3.99 to $95.99 and a data range from 1 GB to 50 GB. Some plans are structured with a fixed data amount that remains unchanged during the validity period, while others use a daily data cap that resets each day, providing flexibility depending on usage patterns.
