JamboSim eSIM Data Plans for Belgium

JamboSim does not provide a truly unlimited data eSIM for Belgium. The plans labeled “Unlimited” deliver 3 GB per day of high‑speed data; once that daily allowance is reached the speed is throttled to 1000 kbps. After the 3 GB/day cap the data remains usable, but at the reduced speed.

Those who need more data can choose from fixed‑amount plans. For example, the eSIM Belgium 20GB/30 days plan costs $6.99 USD and the eSIM JamboSim Europe 50GB/30 days plan costs $72.99 USD. Fixed data plans may offer better value for heavy‑data users than the daily‑cap “Unlimited” options.

JamboSim provides eSIM plans that allow Belgium travel plans to include a phone number and the ability to send SMS. The phone number for these plans comes with the dialing code +1; it is not a local Belgian number, and the plans support outbound voice calls and outbound SMS only, so incoming calls and messages are not supported.

The available plans range in price from $11.99 USD for a 1 GB plan valid for 7 days up to $101.99 USD for a 20 GB plan valid for 365 days, with intermediate options of 2 GB/15 days, 3 GB/30 days, 5 GB/60 days, 10 GB/180 days, and 1 GB/7 days. Travel users who need specific call or messaging functionality should confirm the details directly with JamboSim before purchase.

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.
