Simbye eSIM Data Plans for Southeast Asia

Simbye does not provide an unlimited data eSIM plan for Southeast Asia. Travelers can, however, choose from several fixed‑data options that cover the major countries in the region. For example, the “Asia (7 areas) 50GB 180Days” plan offers 50GB of high‑speed data for 180 days at $60.00 USD, while the “Asia (7 areas) 20GB 30Days” plan gives 20GB of data for 30 days at $30.00 USD. Both plans allow tethering and cover Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam.

Opting for a fixed data plan can be more cost‑effective for most travelers, unless you are an extremely heavy data consumer who would specifically need unlimited usage.

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’s Southeast Asian eSIM coverage comes primarily from its Asia and Asia (7 areas) plans, each of which serves Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam. In addition, the Global139 plan extends that same regional reach and also includes Brunei and Myanmar, while still covering the same seven core Southeast Asian countries. Thus, Simbye’s plans collectively cover Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, Vietnam, Brunei, and Myanmar.
