Your Asia eSIM in two questions
Which Asia eSIM plan fits my route?
Your route might cross several of these 19 countries, and one plan from this bundle can carry you across all of them.
- A three-day hop from Bangkok to Hanoi: standard use fits 500 MB a day for 5 days, and heavy use fits 2 GB a day for 3 days.
- A week from Tokyo to Seoul: 5 GB for 30 days suits standard use.
- Two weeks across Thailand, Vietnam and Indonesia: 10 GB for 30 days suits standard use, and Grab is a ride app in all three countries.
- Just Japan: a trip to Japan alone suits its own eSIM.
Unlike the other 20-country Asia eSIM, this one adds Taiwan, Laos and Kazakhstan, but leaves out Australia and New Zealand.

Nineteen countries share one eSIM, so Tokyo to Bangkok can run on a single line.
- Install, then roam: Add your eSIM at home, and keep data roaming switched on for it at every border. How to turn on data roaming.
- Apps for Japan and Thailand: In Japan, GO, Uber and DiDi cover rides, and LINE is the main messaging app. In Thailand, use Grab or Bolt for rides, and LINE to reach hotels and tour operators.
- Apps for Vietnam and South Korea: In Vietnam, Grab, Be and Xanh SM handle rides, and Zalo and Messenger are the main chat apps. Telegram is blocked there. In South Korea, Kakao T and Uber cover rides, and Naver Map and KakaoMap give walking and transit directions. Many Korean apps ask for a local phone number to sign up.
- Keep your home number: Leave it on for calls and texts, and set up WhatsApp so your chats still reach you. Set up WhatsApp with your home number.
- Top up mid-trip: Most plans can be topped up, so you can add data if your days run heavier than planned.
