RedSim eSIM Data Plans for Cambodia

RedSim does not provide a truly unlimited data eSIM for Cambodia. The plans that carry “Unlimited” in their name give high‑speed data up to 3GB per day and then reduce the speed to 1 Mbps for the remainder of the day, so they are not unlimited in the sense of offering unrestricted high‑speed data.

Travelers who need more data can choose from RedSim’s fixed data plans, such as the 50GB 30‑day plan or the 20GB 30‑day plan, which offer larger data allowances without the daily speed reduction. These fixed plans may be more cost‑effective for users who consume a lot of data.

RedSim does not provide a Cambodia eSIM that includes a local phone number or SMS capability. Only data‑only eSIM plans are offered for that destination. Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but this is not guaranteed in all scenarios, so it is advisable to confirm that the needed services are accessible in Cambodia before purchasing.

RedSim offers 26 single‑country data plans and 17 multi‑country plans in Cambodia. The plans are divided between fixed data amounts—ranging from 1 GB to 50 GB—and daily data caps, which allow customers to lock in a daily quota for the validity period. Prices span from roughly $2.16 to $146.10, covering the full data cap spectrum, and a few plans may come with reduced speeds of 512 kbps or 1000 kbps.
