Billion Connect does not provide an unlimited data eSIM plan for Belize. Travelers who need more data can choose from fixed‑data options such as the 50GB plan that lasts 30 days or the smaller 20GB, 10GB, 5GB, and 1GB plans, which cover 30 days, 30 days, 15 days, 7 days, and 3 days respectively. Selecting a fixed data plan can offer better value for most users, unless you are an extremely heavy data consumer and would be willing to pay a premium for unlimited usage.
