JamboSim eSIM Data Plans for Belgium

JamboSim does not provide a truly unlimited data eSIM for Belgium. The plans that carry the word “Unlimited” in their name give 3 GB of high‑speed data per day; once that daily allowance is reached the speed is reduced to about 1 Mbps, so the data is not unlimited.

Travelers who need more data can choose from JamboSim’s fixed data plans. For example, a 50 GB plan valid for 7 days or a 100 GB plan valid for 180 days are available for Belgium. These plans offer a large amount of high‑speed data within a set validity period and can be more cost‑effective for users who consume a lot of data.

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 one single‑country data plan that covers Belgium. In addition, Belgium is included in a large selection of multi‑country packages—JamboSim’s catalogue contains 52 multi‑country plans that feature Belgium as one of the covered destinations. Across all plans the price range is approximately $1.99 to $195.99, while the data caps vary from around 200 MB to 100 GB. Some of the options offer a fixed data amount (e.g., 1 GB, 10 GB, etc.), whereas others apply a daily data cap that resets each day of the validity period.
