JamboSim eSIM Data Plans for Cambodia

JamboSim does not provide a truly unlimited high‑speed data eSIM for Cambodia. All plans marketed as “Unlimited” deliver 3 GB of high‑speed data per day, after which the speed is throttled to 1 000 kbps.

Travelers who need more data can opt for a fixed‑data plan instead. For example, eSIM JamboSim Asia 20 GB for 30 days is priced at $10.99, and eSIM JamboSim Asia 50 GB for 90 days costs $37.99. These packages give a larger total data allowance and can be more economical unless a user requires constant, unlimited high‑speed connectivity.

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.
