ZenSim eSIM Data Plans for Belgium

ZenSim does not provide a truly unlimited data eSIM plan for Belgium.
All plans that include “Unlimited” in their name actually grant a fixed high‑speed allowance of 3 GB per day, and once that daily limit is reached the data speed is reduced (the specific throttled speed is not listed).

Instead, ZenSim offers several fixed‑data alternatives that may suit most travelers. For example, a 40 GB plan usable for 30 days costs $45; or a 20 GB plan for 15 days costs $23. These fixed‑data options are typically more cost‑effective unless a traveler requires an extremely heavy data consumption that would otherwise hit the daily cap.

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 offers 13 single‑country plans and 13 multi‑country plans that cover Belgium. Among the available options, some plans provide a fixed data amount available for the entire validity period, while others implement a daily data cap that resets each day during the package’s duration. Prices for Belgian plans range from about $5 to $69, with data caps spanning from 1 GB up to 40 GB and validity from 5 to 30 days. When selecting a plan, travelers can choose between the daily‑reset style for frequent short trips or a fixed‑data plan for longer stays, both supported by ties to Belgian connectivity.
