nextSIM does not provide a genuinely unlimited data eSIM for Cambodia. The plans that use “Unlimited” in the name actually offer a capped amount of high‑speed data—either 1GB or 2GB per day—before the speed is reduced to 512 kbps or 2000 kbps. There are therefore no plans that allow unlimited use of high‑speed data without a data limit.
Travelers who need more data can choose from the fixed‑cap options that nextSIM lists for Cambodia, such as the 10GB 30 days plan, the 20GB 30 days plan, or the 30GB 30 days plan, as well as the 30 GB or 40 GB and 50 GB global plans that include Cambodia as part of a larger coverage area. These alternatives provide larger data allowances at a predictable cost, which can be more cost‑effective for users that require substantial data usage.
