eSIMX eSIM Data Plans for Southeast Asia

eSIMX does not provide any unlimited data eSIM for Southeast Asia.
Instead, eSIMX sells fixed data plans. For instance, the Global 100GB 30Days With Calls plan gives 100GB of high‑speed data for 30 days and the Global 50GB 30Days With Calls offers 50GB for the same validity period. These plans cover most Southeast Asian countries and offer 5G connectivity, but they are not unlimited. Choosing a fixed data plan can be more cost‑effective unless a traveler is an extremely heavy data user.

eSIMX does not provide eSIM plans for Southeast Asia that include a phone number or SMS capability. The provider offers only data‑only eSIMs for that region. Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice calls and messaging.

eSIMX offers three primary plans that include Southeast Asian coverage. The East Asia Daily plan includes Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam, and extends to other regions beyond Southeast Asia. The Asia plan covers the same set of Southeast Asian countries—Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam—and also offers coverage in additional regions outside Southeast Asia. The Global plan covers Indonesia, Cambodia, Laos, Malaysia, Philippines, Singapore, Thailand, and Vietnam, with global coverage that extends beyond Southeast Asia. In summary, the Southeast Asian countries covered by eSIMX are Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, Vietnam, and Laos, while the plans also provide access to overseas areas beyond the region.
