ZenSim eSIM Data Plans for Belgium

ZenSim does not provide a truly unlimited data eSIM for Belgium. Their plans called “Unlimited” actually give a daily high‑speed allowance of 3 GB for the validity period; once the 3 GB/day quota is reached the data speed is throttled, although the specific reduced speed is not listed in the available data.

Customers who need more data can choose ZenSim’s fixed‑data plans. For example, a 20 GB plan for 10 days is priced at $23.00 USD, a 20 GB plan for 30 days at $24.00 USD, or a 10 GB plan for 10 days at $15.00 USD. These plans give a larger total data allowance, which may be more cost‑effective for travelers who expect heavy usage.

ZenSim does not provide eSIM plans for Belgium that include a local phone number or SMS capability. Only data‑only eSIMs are available from the provider. Travelers who need to make or receive calls and messages can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection.

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.
