Asia 20 Areas eSIM: One Plan for Multi-Country Trips
Tokyo, Bangkok, and Singapore on one itinerary? An Asia 20 areas eSIM keeps one prepaid profile across roughly twenty destinations—ideal for backpackers and multi-city holidays. Always open the country list: not every “Asia” bundle includes Japan, Korea, or the same Southeast stops.
20-country list
“Asia” on the label is not enough—tick Japan, Thailand, Singapore, and every stop on your route.
7 vs 12 vs 20
Pick the smallest bundle that lists every country you visit.
Long-haul ready
Install on Wi‑Fi before your flight; enable data when you land in Asia.

Two weeks only in Japan? A Japan-only plan may be cheaper—see our Japan guide.
Why travellers pick an Asia 20 areas eSIM
- One purchase, many borders — Backpacking Thailand, Vietnam, and Malaysia? One Asia 20 travel eSIM beats buying a new prepaid SIM in every country.
- Cheaper than roaming — Prepaid Asia 20 areas data gives a fixed price before you fly—no shock bill from your home carrier in Japan or Singapore.
- Install before long-haul — Buy online, scan the QR on Wi‑Fi at home, and enable data when you land—standard for any regional Asia travel eSIM.
Asia 20 vs Asia 7 vs Asia 12: which regional eSIM?
Comparing Asia 20 areas eSIM vs Asia 7 vs Asia 12 is the fastest way to avoid overpaying. A short Southeast loop (Thailand, Vietnam, Cambodia) often fits Asia 7; adding Japan, Korea, or Singapore usually pushes you toward Asia 12 or Asia 20. Open each destination page, search the country list, and match every stop.
