JamboSim eSIM Data Plans for Belgium

JamboSim does not provide a truly unlimited high‑speed data eSIM for Belgium. Every plan that carries the word “Unlimited” in its name caps high‑speed data at 3 GB per day and reduces the speed to 1000 kbps once that limit is reached, so the name does not reflect unlimited data.

If a traveler prefers a data‑limited alternative, JamboSim offers fixed‑data options such as the 20 GB/30 day Belgium plan or the 100 GB/180 day Europe plan. These plans give a larger total data allowance without the daily or throttling restrictions found in the “Unlimited” packages.

JamboSim offers Belgium eSIM plans that include a phone number and the ability to send SMS. Prices start at $11.99 USD for 1GB of data valid for 7 days and rise to $105.99 USD for 20GB of data valid for 365 days. Each plan allows tethering and covers Belgium as well as 164 other countries.

The phone numbers come with the dialing code +1, which is a North American number rather than a local Belgian one. Voice and SMS functions are outbound only, so calls and texts can be sent to other numbers but not received. Users should confirm specific details with JamboSim if they require additional functionality.

JamboSim provides 12 single‑country data plans for Belgium and 47 multi‑country plans that include Belgium. The plans vary from $1.99 to $185.99, offering data caps between 200 MB and 100 GB over validity periods of 3 to 365 days. The catalogue includes fixed data cap plans, which supply a set amount of data for the entire validity window, and daily data cap plans, where the allowance is refreshed each day.
