TraveleSIM.CH eSIM Data Plans for South East Asia

TraveleSIM.CH offers several eSIM products that cover the Southeast Asian countries of Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, Vietnam, Laos, and Brunei. For example, the Sim Card for Asia (7 areas) includes Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand and Vietnam; the Asia (20 areas) product adds Laos to that list; the Asia (12 areas) product includes the six core countries without Laos; the Sim Card for Asia 20 covers all eight ASEAN countries listed above; the Global (120+ areas) plan includes Indonesia, Malaysia, Philippines, Singapore and Thailand; and the Sim Card for Global139 covers Brunei, Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand and Vietnam. A few of these plans also extend coverage beyond Southeast Asia—such as the Asia (20 areas) product, which offers service in a broader region, and the Global plans, which provide worldwide coverage.

TraveleSIM.CH does not provide any unlimited data eSIM plans for South East Asia.
They offer fixed‑data options instead, such as a 50GB plan valid for 180 days that covers Indonesia, Cambodia, Malaysia, the Philippines, Singapore, Thailand, and Vietnam, and a 20GB plan with 30‑day validity for the same region. Choosing one of these fixed data plans can be more economical unless you are an extremely heavy data user who would otherwise require an unlimited package.
