RedSim eSIM Data Plans for Cambodia

RedSim does not provide a true unlimited data eSIM for Cambodia. The plans that carry “Unlimited” in their name actually offer a fixed high‑speed allowance of up to 3 GB per day; after that limit the speed drops to 1000 kbps. If a traveler needs a larger hard data amount, RedSim offers fixed‑data plans such as Asia 50GB 30 Days for $57.95 USD or Asia 20GB 30 Days for $26.96 USD, both of which give the listed data for a full 30 days.

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 provides 16 single‑country data plans and 17 multi‑country plans that cover Cambodia. The plans span a pricing range from $2.25 to $68.00 and data caps from 1 GB up to 50 GB, with validity periods between 1 and 30 days. In addition to traditional fixed‑data plans, the provider offers daily data cap options, allowing users to choose between a set amount of data for the entire validity period or a fixed cap that can be used at any time during that period. This variety lets travelers select a plan that best fits both their budget and usage needs.
