No, CloudOn eSIM does not provide a truly unlimited data eSIM for Cambodia.
The plans that carry “Unlimited” in their names actually give a data cap of 3GB/day (or 2GB/day for the global variants). Once the daily quota is reached, the service speed drops to 1000kbps, which is a reduced speed.
For users who want higher data volumes without the speed cut‑off, CloudOn offers fixed‑data plans such as the Asia 100 GB − 180 days and Asia 50 GB − 90 days, which grant a larger pool of data for that period (both on 5G coverage). These plans are usually more cost‑effective for travelers who do not need continuous unlimited bandwidth.
