eSIM for travel in Asia
Asia is the world’s fastest-growing travel region, and eSIM adoption here is massive — Japan, South Korea, and Southeast Asia all have excellent mobile infrastructure and widespread eSIM support from local carriers like NTT Docomo, SoftBank, SK Telecom, and TrueMove.

What makes Asian eSIMs different
- Japan: Excellent coverage but the most plan options — you can find plans from 3 days to 30 days with data from 1 GB to unlimited
- Southeast Asia (Thailand, Vietnam): Very budget-friendly — plans start at $4.00, and local tourist SIMs at the airport are often more expensive than an eSIM bought in advance
- China: An eSIM is especially useful here because it bypasses the need to register a physical SIM with your passport — plus many Western apps work normally over an eSIM data connection
