RoameSIM eSIM Data Plans for Cambodia

RoameSIM does not provide a true unlimited data eSIM for Cambodia. The plans that carry “Unlimited” in their names are fixed data plans that offer 3GB of high‑speed data per day for a set number of days; after 3GB is used in a given day the speed is reduced to 1Mbps. If a traveler needs a larger data allowance, RoameSIM offers fixed data bundles such as the 100GB plan valid for 180 days or the 50GB plans valid for 7, 15, or 30 days, which avoid the daily speed throttling and can be more cost‑effective for heavy data users.

RoameSIM does not offer a Cambodia eSIM plan that includes a phone number or SMS capability. The provider currently sells only data‑only packages for Cambodia. Travelers who need voice or text functionality can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may block or restrict these services, so it is advisable to verify that the apps you rely on are accessible in Cambodia before purchasing.

RoameSIM offers 12 single‑country data plans for Cambodia and 30 multi‑country plans that include Cambodia among other destinations. The plans vary in data capacity from 1 GB up to 100 GB and are priced between $4.69 and $182.81. Within the single‑country offerings, there are both daily data‑cap plans—where the data limit resets each day—and fixed‑data‑cap plans that provide a set amount for the entire validity period. The multi‑country plans follow the same pricing and data ranges, allowing travelers to choose the bundle that best suits their usage.
