JamboSim eSIM Data Plans for Cambodia

JamboSim does not provide a truly unlimited data eSIM for Cambodia. The plans that carry the word “Unlimited” in their name give 3GB of high‑speed data each day and then throttle the connection to 1000kbps once the daily amount is exceeded. Therefore, after the stipulated amount is used each day the speed is reduced, and the plan is not unlimited in the sense of providing unrestricted high‑speed data.

Customers who need more data without the daily cap can choose from JamboSim’s fixed‑data options. For example, a 20GB eSIM is available for 30 days at a price in the $10–$20 USD range, and larger plans such as 50GB for 90 days or 100GB for 180 days give more flexibility for heavy users. These fixed‑data plans may be a more cost‑effective choice for travelers who anticipate extensive data usage in Cambodia.

JamboSim does not provide an eSIM plan for Cambodia that includes a local phone number or SMS capability. The available plans from JamboSim are data‑only and do not support inbound or outbound calls or text messages.

Travelers can still communicate while in Cambodia by using internet‑based messaging and voice services such as WhatsApp, Telegram, and iMessage, which operate over the data connection and do not require a local phone number or SMS permission.

JamboSim offers 12 single‑country plans and 33 multi‑country plans that include Cambodia. Prices range from $1.99 to $99.99, while data caps span 200 MB to 100 GB with validity periods from 3 to 365 days. The catalog includes both daily data‑cap options—where a set amount of data is available each day—and fixed‑cap plans that provide a total data volume for the entire validity period. Many plans allow tethering and some are limited to reduced speed of 1000 kbit/s.
