ZenSim eSIM Data Plans for Belgium

ZenSim does not offer a truly unlimited data eSIM for Belgium.
The plans that carry the “Unlimited” name actually provide a 3GB per day cap, after which the speed is reduced; therefore they are not unlimited high‑speed data plans.

Instead, ZenSim sells fixed data plans that may suit most travelers. For example, the Belgium 20GB plan is available for 10 days at $23.00 USD and for 30 days at $24.00 USD, offering a larger data allowance that can be more cost‑effective for users who need a lot of data without the daily limit.

ZenSim does not provide Belgium eSIM plans that include a phone number or SMS capability. All available plans are data‑only and cannot be used for traditional voice calls or for receiving or sending SMS messages.

Travelers wishing to stay in contact can use the data connection to run VoIP applications such as WhatsApp, Telegram, or iMessage, which allow calls and messaging over an internet connection without requiring a local phone number or SMS service.

ZenSim provides a total of 16 distinct data packages available for Belgium—eight single‑country options and eight multi‑country options. The single‑country plans allow users to stay connected in Belgium alone, while the multi‑country versions enable connectivity across several European destinations. Among these packages, users can choose between fixed data caps of 3 GB to 20 GB and daily‑reset data caps that refresh each day, giving flexibility depending on travel patterns. Prices for the Belgian plans range from about $11 to $57, with validity periods between 10 and 30 days, making it easy to find a package that matches short trips or slightly longer stays.
