MobileSIM eSIM Data Plans for Belgium

MobileSIM does not provide a truly unlimited data eSIM for Belgium. All of its plans described with “Unlimited” in the name actually offer a maximum of 3 GB per day of high‑speed data; after that amount the speed is reduced to 1000 kbps, so the data cap is effectively a hard limit.

Travelers looking for large amounts of data should consider MobileSIM’s fixed data plans. For example, the Belgium 20 GB for 30 days plan gives a substantial data allowance at a lower price than the daily “Unlimited” options, and the Global 60 GB for 125 days plan offers a very high data volume for extended travel, both of which may be more cost‑effective for heavy data users.

MobileSIM does not offer eSIM plans for Belgium that include a phone number or SMS capability. The provider only sells data‑only eSIMs for Belgium, so travelers will not receive a local phone number or the ability to send or receive traditional text messages.

If a traveler needs to make calls or send messages, popular VoIP apps such as WhatsApp, Telegram, and iMessage can usually be used over the data connection, but some destinations may block or restrict access to specific apps or VoIP services. Travelers should verify that the apps they rely on are accessible in Belgium before purchasing a MobileSIM data‑only plan.

MobileSIM provides 12 single‑country data plans and 10 multi‑country plans for travelers in Belgium. The catalogue includes both daily data cap options, which reset each day, and fixed data cap options that count toward a single total limit for the plan’s validity. Prices generally range from about $2.30 up to $165, while data allowances span from 200 MB to 60 GB, giving a broad selection that can suit short‑term visits or longer stays.
