ETravelSim eSIM Data Plans for Southeast Asia

ETravelSim does not offer an unlimited data eSIM plan for Southeast Asia. A fixed‑data alternative is available, such as the 50GB eSIM valid for 30 days or the 50GB eSIM valid for 365 days. Choosing a fixed data plan can be more cost‑effective unless the traveler is an extremely heavy data consumer.

ETravelSim does not provide Southeast Asia eSIMs that include a phone number or SMS capability. The provider offers only data‑only plans for this destination. Travelers who need to stay in touch can use popular VoIP applications such as WhatsApp, Telegram, or iMessage, which work over the data connection and allow voice calls and messaging without a local phone number or SMS service.

ETravelSim offers several eSIM plans that cover Southeast Asian destinations. The Travel eSIM for Asia plan includes Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam. The Southeast Asia eSIM plan adds Cambodia and Laos to that list, covering Indonesia, Cambodia, Laos, Malaysia, Philippines, Singapore, Thailand, and Vietnam. The Seafarer eSIM, which spans 180 countries, also includes the same Southeast Asian countries: Indonesia, Cambodia, Laos, Malaysia, Philippines, Singapore, Thailand, and Vietnam. Finally, the Global Flex 365 eSIM covers Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam. None of the plans list Brunei, Timor‑Leste or Myanmar as coverage areas.
