EtravelSIM eSIM Data Plans for Southeast Asia

EtravelSIM does not sell an unlimited data eSIM for Southeast Asia. All of its available plans provide a fixed data allowance, ranging from 20 GB to 50 GB, with validity periods of 30 days or 365 days.

Travelers who need more data can buy a larger fixed plan instead. For example, the 50 GB 30‑day eSIM is priced at $80.99 USD and covers Indonesia, Malaysia, Philippines, Singapore, Thailand, Vietnam and five additional countries, while the 20 GB 30‑day eSIM costs $27.00 USD and covers a similar set of Southeast Asian countries. Choosing a fixed data plan can be more cost‑effective unless an extremely heavy data user requires no data cap at all.

EtravelSIM does not provide a telephony‑enabled eSIM for Southeast Asia; all of its available plans are data‑only and do not include a local phone number or SMS capability. Travelers who need a number for calling or texting will need to rely on internet‑based services. Popular VoIP applications such as WhatsApp, Telegram, and iMessage work over the data connection and can be used for calls and messaging without a phone number or SMS feature.

The available Southeast Asian coverage under EtravelSIM is comprised of Indonesia, Malaysia, Philippines, Singapore, Thailand, Vietnam, and Laos. The Travel eSIM for Asia and Global Flex 365 eSIM plans list Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam. The Southeast Asia eSIM and Seafarer eSIM (180 countries) plans add Laos to that list, covering Indonesia, Laos, Malaysia, Philippines, Singapore, Thailand, and Vietnam.
