Saily eSIM Data Plans for Belgium

Saily does not provide a truly unlimited data eSIM plan for Belgium. The only plan named “Belgium UNLIMITED 15 days” actually offers 5 GB of high‑speed data per day and slows the connection to 1024 kbps after the daily quota is reached, so it is not an unlimited plan in the sense of unrestricted high‑speed data.

If a visitor to Belgium needs a large data allowance, Saily offers fixed‑data alternatives. For example, the Belgium 20 GB 30‑day plan provides 20 GB of high‑speed data for 30 days, and the Belgium 10 GB 30‑day plan gives 10 GB for the same period. These plans are available for purchase and can be more cost‑effective for users who anticipate heavy data use, as they avoid the throttling that occurs once the daily cap on the “UNLIMITED” option is reached.

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 a total of 17 data plans for Belgium, consisting of 6 single-country plans and 11 multi-country plans. These plans range in price from approximately $3.99 to $95.99 and provide data allowances from 1GB to 50GB. Some plans offer a fixed data amount, while others have a daily data cap. Certain plans may experience reduced speeds after reaching a specific data usage threshold.
