Instabridge does not provide an unlimited data eSIM for Cambodia. All of its Cambodia plans have a set data cap, ranging from 1 GB up to 20 GB, and a fixed validity period.
If you need a large amount of data, you can choose a fixed data plan such as the 20 GB Cambodia eSIM Mobile Data Plan, which is valid for 7 days, or the 10 GB plan, valid for 30 days. These options can be more cost‑effective for most travelers, unless an extreme data‑heavy use case is required.
