Best eSIM for Asia Travel: Country by Country

Asia is tricky because each country has its own network rules. A single Asia eSIM can save money, but per-country plans are often cheaper for longer stays.

• Japan: 10 GB for about $18, 5G ready on major carriers
• Thailand: 15 GB for roughly $9, valid 30 days
• Vietnam: 10 GB around $7, strong coverage in cities
• Indonesia: 12 GB near $10, best on Telkomsel network

For a multi-country tour, a regional Asia plan beats buying a new SIM at every border.
