Your Asia eSIM in two questions
Which Asia eSIM plan fits my route?
In this bundle, Taiwan and Hong Kong sit alongside Vietnam, Thailand and Indonesia, so one eSIM can carry you across a proper route.
- A three-day trip through Taiwan and Hong Kong: the 1 GB for 7 days plan suits light use, with maps, messages and email.
- A week through Thailand and Vietnam: choose the 5 GB for 30 days plan for standard use, which covers social media, music and some video.
- Two weeks in Japan and South Korea with heavy use: the 2 GB a day for 15 days plan gives you a daily allowance for streaming and a hotspot.
- Japan alone: if Japan is your only stop, the Japan eSIM suits that trip.
This bundle covers Bangladesh, Laos and Taiwan, which the 20-country Asia eSIM does not; that one covers China and Singapore instead.

Using one eSIM across Asia: tips
From Tokyo to Bali, and Hanoi to Macau, one eSIM spans 14 countries. Here's how to get the most from it.
- Install at home: Set up your eSIM before you fly. At every border, keep data roaming switched on for the eSIM line. Need the steps? See how to turn on data roaming.
