eSIMCard eSIM Data Plans for Southeast Asia

eSIMCard does not provide a truly unlimited data eSIM for Southeast Asia. The plans listed under the name “Unlimited” all contain a fixed high‑speed data allowance—1GB or 2GB per validity period—after which the speed drops to a reduced rate of 512kbps or 2000kbps.

Travelers who need large data capacities can choose one of the fixed‑data plans instead. For example, eSIMCard offers a 100GB eSIM for 30 days in Southeast Asia at $109.25 USD, or a 100GB plan for 180 days at $132.43 USD. These fixed plans give full high‑speed data throughout the validity period, and many users find them more cost‑effective unless they have extremely heavy data demands.

eSIMCard does not provide Southeast Asia eSIMs that include a local phone number or SMS capability. The provider offers only data‑only plans for the region. Travelers can still use popular VoIP services such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging, but no native telephony or SMS support is included.

The eSIM Data For in Asia plan covers Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam, and it also includes additional territories beyond Southeast Asia. The eSIM Data For in Global Lite plan includes the same Southeast Asian countries as well as Cambodia in its coverage and extends to other regions outside the area. The eSIM Data For in Global Max plan adds Laos and Myanmar to the list of Southeast Asian countries it serves, and similarly offers coverage in other global regions. The eSIM, , , Global, Unthrottled plan is available for Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam, with further coverage in regions beyond Southeast Asia.
