aloSIM does not offer an unlimited data eSIM specifically for Belgium. All Belgium‑only plans listed have a hard cap of 50GB, and the Belgium‑specified plans are valid for 10, 15, or 30 days. The only plan with more data is the Europe‑wide option, which provides 100GB for 180 days and covers Belgium as part of its broader coverage area.
If you need a larger data allowance, the fixed‑data plans are the options available. For example, the Belgium 50GB for 30 days plan or the Europe 100GB for 180 days plan provide substantial data for typical travel needs. These fixed plans may be more cost‑effective unless you are a very heavy data user, in which case a different provider with an unlimited offer would be required.
