Lumbus eSIM Data Plans for Cambodia

Lumbus does not provide a truly unlimited high‑speed data eSIM for Cambodia. The plans named “Cambodia Unlimited” actually deliver 3GB of 4G data each day and, after that daily allowance, the speed is reduced to 1 Mbps. This daily limit and throttled speed mean the data is not unlimited.

Travelers looking for larger, fixed data allowances can choose from Lumbus' fixed plans such as the 20GB 30‑day plan, the 50GB 180‑day plan covering Cambodia and several other countries, or the 50GB 180‑day plan that uses 5G where available. These options offer a set amount of high‑speed data for a specific validity period and may be more cost‑effective unless one requires a truly unlimited daily data package.

Lumbus does not provide a Cambodia eSIM that includes a local phone number or SMS capability. Travelers can purchase only data‑only plans for use in Cambodia.

Users can still make voice calls and send messages through popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but the availability of these services may vary. Travelers should confirm that the VoIP apps they rely on are accessible in Cambodia before buying a data plan.

Lumbus offers a total of 10 single‑country eSIM plans that are valid only for Cambodia, as well as 30 multi‑country plans that include Cambodia among other destinations. The single‑country plans vary from a few gigabytes of data at the low end to a sizable 50‑GB capacity, and are priced between about $3 and $141, with validity periods ranging from a single day up to a full year.

Among the single‑country offerings, four are daily data‑cap plans that refresh each day, while the remaining plans provide a fixed data cap that lasts for the length of the validity period. The multi‑country plans similarly combine both daily and fixed data‑cap options, giving travelers flexibility depending on whether they need a predictable amount of data for the entire stay or a daily allotment that can be reused each day.
