No, simpleSIM does not provide a true unlimited data eSIM for Cambodia. The plans that carry “Unlimited” in the name all have a fixed data allowance – for example, eSIM Cambodia Unlimited - 1 day offers 1GB of high‑speed data and throttles to 512kbps after the limit is reached, while eSIM Asia Unlimited - 3 days gives 3GB/day with a reduced speed of 1000kbps once the cap is hit. For travelers looking for a larger, unthrottled data supply, simpleSIM offers fixed data plans such as the eSIM Asia 50GB plan, which provides 50GB for 90 days, or the eSIM Cambodia 20GB + Calls & Texts plan, which includes 20GB for 30 days. These fixed data plans can be more cost‑effective for most users and keep data usage predictable over the validity period.
