Lumbus eSIM Data Plans for Cambodia

No Lumbus plan provides truly unlimited high‑speed data for Cambodia. All Lumbus offerings have a hard data cap. For example, the “Cambodia Unlimited” plans give 3GB of high‑speed data each day for 3, 7, 14, or 30 days; after the daily limit is reached, speed is reduced to 1000kbps. A fixed‑data alternative is the “Cambodia 20GB 30Days” plan, which offers 20GB of high‑speed data valid for 30 days. These fixed‑data plans can be more cost‑effective for most travelers while still delivering substantial data allowances.

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.
