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 offers several Southeast Asia eSIM plans that include a virtual phone number and two‑way SMS capability. Prices start at $10.99 USD for a 4 GB data bundle valid for 30 days and rise to $80.99 USD for a 50 GB bundle of the same duration; larger 365‑day plans range from $29.99 USD to $109.99 USD. All plans provide a phone number with the dialing code +44 (UK), except the Southeast Asia eSIM 20 GB and Seafarer eSIM, which use +33 (France), and they allow both inbound and outbound voice calls as well as inbound and outbound SMS. Travelers should confirm directly with EtravelSIM if they need a local dialing code or specific SMS functionality.

The Travel eSIM for Asia plan covers Indonesia, Malaysia, Philippines, Singapore, Thailand and Vietnam. The Southeast Asia eSIM plan extends that coverage and adds Laos. The Seafarer eSIM, which provides service to 180 countries, likewise covers Indonesia, Malaysia, Philippines, Singapore, Thailand, Vietnam and Laos, and offers additional destinations beyond Southeast Asia. The Global eSIM concentrates on Indonesia, Malaysia, Philippines, Singapore, Thailand and Vietnam while also providing roaming to a wide range of other regions.
