BetterRoaming does not provide an unlimited data eSIM for Global (World). The available Global (World) plans are fixed data bundles. For example, a 5GB bundle is valid for 30 days and costs $34.99 USD, a 3GB bundle is also valid for 30 days and costs $23.99 USD, and a 1GB bundle is valid for 7 days and costs $8.99 USD.
Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user is an extremely heavy data consumer who would prefer an unlimited option.
