Strong eSIM eSIM Data Plans for Southeast Asia

Strong eSIM does not provide an unlimited data eSIM for Southeast Asia.
All of its Southeast Asia plans carry fixed data caps. For example, Strong eSIM offers a 50GB plan valid for 180 days at $146.90 USD, and a 20GB plan valid for 30 days at $65.90 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 travelers, unless a user requires extremely heavy data usage that would exceed the available allowances.

Strong eSIM does not provide an eSIM plan for Southeast Asia that includes a phone number or SMS capability. Strong eSIM only offers data‑only eSIMs for Southeast Asia, so travelers will need to use data‑based services such as WhatsApp, Telegram, or iMessage to make calls and send messages.

Strong eSIM offers several plans that cover a wide range of Southeast Asian destinations. The Asia (7 areas) /Day plan includes Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam; the Singapore & Malaysia & Vietnam & Th plan covers Indonesia, Malaysia, Singapore, Thailand, and Vietnam; the Asia (20 areas) /Day plan adds Laos to those eight countries; the Asia (12 areas) /Day plan covers Indonesia, Cambodia, Malaysia, Singapore, Thailand, and Vietnam; the Global (120+ areas) /Day plan lists Indonesia, Malaysia, Philippines, Singapore, and Thailand; the Asia‑20 plan again covers Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam; and the Global139 plan includes all of the above plus Brunei. In summary, Strong eSIM’s plans in Southeast Asia cover Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, Vietnam, Laos, and Brunei, while Timor‑Leste and Myanmar are not part of any current plan.
