eSIMatrix eSIM Data Plans for Southeast Asia

eSIMatrix does not provide an unlimited data eSIM specifically for South East Asia; all available plans in that region have fixed data allowances.
Travelers can choose from fixed‑data options such as the 20 GB plan valid for 30 days, priced at $41.00 USD, or the 20 GB plan valid for 15 days at $39.50 USD. These plans offer a clear data quota and a set validity period. For users who anticipate very high data consumption, a fixed plan may be more cost‑effective than purchasing a short‑term unlimited plan.

eSIMatrix does not offer any eSIM plan that includes a local phone number or SMS capability for travelers in South East Asia. All of its Southern Asian eSIM offerings are data‑only, providing only internet access for the validity period of the plan.

Travelers who need to make voice or text communications can use popular VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, which works without a local phone number or SMS capability.

The eSIMatrix plan named “Asia” covers the South East Asian countries Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam, while also extending coverage to Australia, China, Hong Kong, Japan, New Zealand, and Taiwan.
