Simbye does not provide an unlimited data eSIM plan for Cambodia. All of the available offerings have a hard data cap as shown in the Data cap column.
The provider offers fixed data plans instead. For example, a 100GB bundle is available for 30 days at $59.99 USD, a 50GB bundle for 30 days at $49.99 USD, a 50GB bundle for 180 days at $59.99 USD, and smaller 20GB bundles for 30 days at $29.99 USD. These plans can be suitable for most travelers, and choosing a fixed data plan may be more cost‑effective than purchasing an unlimited option that is not offered.
