Avelis eSIM does not provide an unlimited data eSIM for Belize. The available options are fixed data plans that must be used within a set validity period. For example, Avelis eSIM offers a 20GB plan valid for 30 days, a 10GB plan also valid for 30 days, a 5GB plan for 30 days, a 3GB plan for 15 days, and a 3GB plan for 30 days. These plans include tethering and are priced at $215.99 USD, $117.99 USD, $63.99 USD, $38.99 USD, and $39.19 USD respectively. Choosing a fixed data plan can be more cost‑effective unless a traveler is an extremely heavy data consumer.
