Lumbus eSIM Data Plans for Cambodia

Lumbus does not provide a truly unlimited data eSIM for Cambodia. The plans that carry the name “Cambodia Unlimited” actually offer a limit of 3 GB per day; after the daily quota is reached, data speeds are reduced, although the exact throttled speed is not specified.

Instead, Lumbus offers a range of fixed‑data plans that may be more cost‑effective for travelers who need more data. For example, a 20 GB plan valid for 30 days is available for $50.99, and a 50 GB plan valid for 180 days costs $90.99. These options give users a larger high‑speed data allowance and avoid the daily cap found in the “Unlimited” labeled plans.

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 provides 11 single‑country data plans for Cambodia and 32 multi‑country plans that include Cambodia coverage. The available plans range in price from $4.99 to $179.99 and offer data caps from 500 MB up to 50 GB, with validity periods spanning from one day to a full year. The single‑country options focus on a fixed data amount, while the multi‑country plans feature daily data capping options for travelers who need consistent data use across different countries.
