Instabridge does not provide an unlimited data eSIM for Belgium. All of the plans listed for Belgium have a fixed data cap, with the largest offering 20GB of data.
Travelers who need a large data allowance can choose from Instabridge’s fixed data plans, such as the 20GB Belgium eSIM Mobile Data Plan that is valid for 7 days or the 10GB Belgium eSIM Mobile Data Plan that is valid for 30 days. These options can be more cost‑effective for most users unless an extremely heavy data consumer requires unlimited data.
