RedSim eSIM Data Plans for Southeast Asia

RedSim does not provide a truly unlimited data eSIM for Southeast Asia. The plans labelled “Asia Unlimited” give high‑speed data up to 3GB each day, after which the speed is throttled to 1000kbps. These plans are fixed data bundles with a hard cap, not a continuous unlimited data service.
If you need larger data volumes you can choose one of RedSim’s fixed data plans, such as the 50GB 30‑day plan or the 20GB 30‑day plan, both of which offer a set amount of high‑speed data that must be used within the validity period.

RedSim does not provide an eSIM that includes a local phone number or SMS capability for Southeast Asia. The provider offers only data‑only plans for that region.

Travelers who need to make voice calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may block or restrict certain apps or services. It is advisable to verify that the apps you rely on are accessible in Southeast Asia before purchasing.

RedSim offers two plans that cover Southeast Asia. The Asia plan includes Indonesia, Cambodia, Laos, Malaysia, Philippines, Singapore, Thailand and Vietnam. The Global plan adds Brunei and Timor‑Leste to those countries, offering coverage for Indonesia, Cambodia, Laos, Malaysia, Philippines, Singapore, Thailand, Vietnam, Brunei and Timor‑Leste.
