eSIMX eSIM Data Plans for Southeast Asia

eSIMX does not offer any unlimited data eSIM for South East Asia. All of its plans provide a fixed data allowance. Among the highest‑cap options are the Asia 15GB 7Days plan costing $42.80 USD and the Asia 15GB 30Days plan costing $48.80 USD, both covering Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, Vietnam and 12 additional countries. If a traveler does not need extremely heavy data usage, choosing a fixed‑data plan such as these can be more cost‑effective than searching for an unlimited alternative, which is not available from eSIMX for this region.

eSIMX does not provide eSIMs for Southeast Asia that include a phone number or SMS capability; only data‑only plans are offered.
Travelers can still communicate via internet‑based services such as WhatsApp, Telegram and iMessage, which use the data connection for calls and messages.

The eSIMX “Asia” plan is the only plan that covers South East Asian countries. It includes Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam. The same plan also extends coverage to several other regions, but those areas are not part of the South East Asian coverage.
