Simbye eSIM Data Plans for Southeast Asia

Simbye does not provide an unlimited data eSIM for Southeast Asia. Travelers who need continuous data access will find fixed‑data plans instead. For example, the South East Asia 50GB 180‑day plan costs $59.99 USD, while the South East Asia 20GB 30‑day plan is $29.99 USD. These fixed plans can be more cost‑effective for most users, although an exceedingly heavy data user may prefer a plan with higher data limits.

Simbye does not offer an eSIM for Southeast Asia that includes a phone number or SMS capability. The provider’s Southeast Asia plans are data‑only and do not provide inbound or outbound voice or SMS services. Travelers can use a data connection to run messaging and calling apps such as WhatsApp, Telegram, or iMessage, which work over the internet without needing a local phone number or SMS function.

Simbye offers two eSIM plans that cover Southeast Asian destinations. The Asia plan includes Indonesia, Laos, Malaysia, Philippines, Singapore, and Thailand. The South East Asia plan covers Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam. No other Southeast Asian countries are listed in these plans, and the Asia plan also extends to additional regions outside Southeast Asia, but those are beyond the scope of the question.
