MobileSIM eSIM Data Plans for Belgium

MobileSIM does not provide a truly unlimited data eSIM for Belgium. The plans that are labeled “Unlimited” in the name, such as Belgium Unlimited data for 10 days, actually offer 3 GB of high‑speed data per day and switch to a reduced speed of 1000 kbps after that limit is reached, so they are not unlimited in the strict sense.

Travelers who need larger data allowances can choose from the fixed‑data plans that MobileSIM offers for Belgium. One example is the Belgium 20 GB for 30 days plan, which delivers 20 GB of high‑speed data over 30 days. Another option is the Europe 50 GB for 30 days plan, which gives 50 GB across Belgium and other European countries for 30 days. These fixed plans are often more cost‑effective unless a user requires a very large amount of data with no speed throttling.

MobileSIM does not provide any Belgium eSIM plans that include a local phone number or the ability to send and receive SMS messages. The available plans are data‑only, offering connectivity without voice or text services.

Travelers wishing to make calls or send messages while in Belgium can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection provided by the MobileSIM eSIM.

MobileSIM lists seven single‑country plans that are specifically tailored for Belgium, in addition to 17 multi‑country plans that include Belgium among their coverage areas.

The provider’s offerings span a broad price range from about $3 to $185 USD, with data caps from 500 MB up to 100 GB. Daily‑cap options are limited to two plans, whereas the majority of plans—twenty‑two—provide a fixed data allotment for the entire validity period. This structure allows travelers to choose either a set amount of data that lasts the whole voucher duration or a daily data allowance that resets each day, with the choice typically depending on the length of stay and usage pattern.
