Avelis eSIM does not provide an unlimited data eSIM for Belgium. The available plans for Belgium are fixed data plans, such as the Standard 50GB / 180 Days plan, the Standard 50GB / 30 Days plan, and the Standard 20GB / 30 Days plan. These plans offer 5G connectivity and tethering, and they are priced at $43.99, $63.99, and $16.99 USD respectively. Choosing a fixed data plan can be more cost‑effective for most travelers unless they are extremely heavy data users.
