gosimless does not offer any unlimited data eSIM plans for Belize. Travelers looking for a larger data allocation can choose from fixed‑data plans, such as the Belize 20GB – 30 days plan priced at $168.49 USD or the Belize 10GB – 30 days plan at $91.99 USD. Selecting a fixed data plan may be more cost‑effective for most users, unless someone requires very heavy data usage daily.
