Flysimio does not offer an unlimited data eSIM plan for Southeast Asia. All available plans have a data cap. For travelers needing a larger allowance, the table includes a 50GB plan valid for 180 days at $112.50 USD and a 20GB plan valid for 30 days at $50.00 USD. These fixed‑data options cover Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam.
Choosing a fixed data plan can be more cost‑effective for most users because it provides a clear data limit and price without the higher cost that often accompanies unlimited offerings. Travelers who anticipate extremely heavy data use might consider adjusting the plan duration or quantity instead of seeking unlimited coverage.
Flysimio does not provide any eSIM plans for Southeast Asia that include a local phone number or SMS capability. All plans sold by Flysimio for this region are data‑only; they offer high‑speed 5G/4G internet but no inbound or outbound voice or text features. Travelers can still use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages.
Flysimio offers three eSIM plans that cover Southeast Asian countries. The Asia (7 areas) plan includes coverage in Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand and Vietnam, while the Asia‑20 plan also covers those same seven Southeast Asian countries and expands to other regions beyond Southeast Asia, with additional coverage in places such as Australia, China, Hong Kong, Israel, India, Japan, South Korea, Kuwait, Sri Lanka, Macau, New Zealand, Pakistan and Saudi Arabia. The Global (120+ areas) plan covers Indonesia, Malaysia, Philippines, Singapore and Thailand, and extends to many regions outside Southeast Asia. All plans can be grouped by the Southeast Asian countries they cover—Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand and Vietnam—with the Asia (7 areas) and Asia‑20 plans covering the full list and the Global plan covering a subset.
