Best eSIM for Asia: regional plans for a multi-country trip
Japan, Thailand, Vietnam and Singapore on one profile. What the regional Asia plans include, and where they fall short.
Asia is the region where a regional eSIM saves the most, because a two-week trip often crosses three or four countries. The plans are also less standardised than in Europe: country lists differ, some exclude Japan, and the data allowances are often smaller than the headline suggests.
This comparison covers the plans that work across Japan, Thailand, Vietnam, Singapore and Malaysia, priced for a two-week trip with normal use.
-
Airalo Asialink
The broadest country list in the region, including Japan, South Korea, Thailand, Vietnam, Singapore and Malaysia. Fixed data with hotspot included, which makes it the practical pick for a laptop-friendly trip.
-
Saily Asia
Cheaper per gigabyte than Asialink and simple to set up in the app. The country list is slightly narrower and plan sizes change with the season, so check that every country on your route is included before you buy.
-
Holafly Asia
Unlimited data for travellers who stream or tether, with a country list that covers the main destinations. The fair-use threshold is daily, and hotspot is limited on some plans.
-
Nomad Asia
A smaller provider with competitive regional pricing and a clear country list. Fewer plan sizes, but the fixed-data plans are straightforward and the app is simple.

What this does not solve
Regional plans are convenient, not always cheaper. For a trip that stays in one country, a single-country plan is usually better value, and for Japan specifically the network you attach to matters more than the regional label. Check the country list twice: a plan sold as Asia does not always include every country on your route.
