Simfinity eSIM Data Plans for Southeast Asia

Simfinity does not provide a truly unlimited data eSIM for Southeast Asia; all of its plans have a fixed data cap, the largest being 25GB. Travelers looking for a high‑volume fixed plan can choose, for example, the Global eSIM that offers 25GB for $104.90 USD with unlimited validity, covering Cambodia, Indonesia, Laos, Malaysia, the Philippines, Singapore, Thailand, Vietnam and 98 additional countries. Another option with a lower data allowance is the 10GB Global eSIM for $53.71 USD, which also has unlimited validity. Opting for a fixed data plan can be more cost‑effective unless the user requires truly unlimited data usage.

Simfinity does not provide eSIM plans for Southeast Asia that include a phone number or SMS capability. Only data‑only eSIMs are offered by the provider in that region. Travelers can still use popular VoIP apps such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages.

Simfinity offers several eSIM plans that include the Southeast Asian nations of Cambodia, Indonesia, Laos, Malaysia, Philippines, Singapore, Thailand and Vietnam. The Global eSIM, East Asia Pass, Asia Pacific Pass and World Wide Pass all list these countries as part of their coverage, while each plan also extends to regions beyond Southeast Asia (the specific destinations outside the region are not listed here).
