No unlimited data eSIM options are offered by eSIM‑On Shop for Belgium. Travelers can choose from fixed‑data plans that provide a range of allowances and validity periods. For instance, the Be Belgium 50GB plan is valid for 180 days and costs $55.00 USD, while the Be Belgium 20GB plan is valid for 30 days and costs $26.50 USD. These larger‑allowance packages tend to be more cost‑effective for users who anticipate heavy data use, whereas a lightweight 10GB or 5GB plan might better suit casual travelers.
