eSIMNow does not provide an unlimited data eSIM for Belize. The only options available are fixed data plans with a set amount of high‑speed data that must be used within a specified validity period.
For example, eSIMNow offers a Belize 20GB 30Days plan, priced at $219.79 USD, and a Belize 10GB 30Days plan, priced at $119.91 USD. These fixed data plans may be more cost effective for most travelers, though an extremely heavy data user might consider a different service.
