## 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](/esim/japan).

Unlike the other 20-country Asia eSIM, this one adds Taiwan, Laos and Kazakhstan, but leaves out Australia and New Zealand.

## Which countries and networks does the Asia eSIM cover?

19 countries, from Japan to Kyrgyzstan, all on one eSIM. And 13 of them have 5G.

Your phone switches network by itself at each border, so there's nothing to pick. Here are three of the stops and the networks you'll join:

- **Japan:** KDDI/au, NTT docomo and Rakuten Mobile
- **Thailand:** AIS, CAT and TrueMove H
- **Vietnam:** MobiFone and Vietnamobile

Your data reaches the internet through the United Kingdom or Norway, which is a normal setup for travel eSIMs. [How IP addresses work abroad](/help/ip-address-another-country) explains more.

## Using one Asia eSIM across borders: tips

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](/help/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](/help/keep-whatsapp-and-home-number).
- **Top up mid-trip:** Most plans can be topped up, so you can add data if your days run heavier than planned.

## Questions

### How much is an eSIM for Asia?

Asia eSIMs start at £4.99 for 500 MB a day over 1 day. A 5 GB plan for 30 days costs £31.99. Prices include any taxes and show in pounds, euros or dollars.

### Which countries does the Asia eSIM cover?

One eSIM works in all 19 countries: Bangladesh, China, Hong Kong, Indonesia, India, Japan, Kyrgyzstan, South Korea, Kazakhstan, Laos, Sri Lanka and Malaysia and more. The full list with the network in each country is on this page.

### When does my Asia eSIM start?

Most plans start the moment your eSIM first connects to a network in Asia, so you can buy and install it at home before you fly. Install it within 180 days of buying.

### Can I top up my Asia eSIM?

Yes. Most Asia plans can be topped up from your eSIM page in two taps, with no new QR code. The plan table on this page shows which ones.

### Does it come with a phone number?

Every eSIMology plan is data only. Keep your own SIM switched on for calls and texts, and use WhatsApp, FaceTime or any calling app over your eSIM's data.

### What if my plans change?

Cancel an eSIM you haven't installed within 30 days for a full refund to your card, in two taps from your eSIM page.

### Can I use one Asia eSIM for Thailand and Vietnam?

Yes, both countries are on this 19-country eSIM, so one install covers the route. Grab is a ride app in both, and in Thailand, LINE is the main way to message locals, hotels and tour operators.

### Can I use Telegram in Vietnam on the Asia eSIM?

Yes, Vietnam is on this 19-country eSIM, but Telegram is blocked there. Zalo and Messenger are the messaging apps to use instead, and you can open both on your mobile data.

### Can I use GO or Uber in Japan on the Asia eSIM?

Yes, Japan is on this 19-country eSIM, and GO, Uber and DiDi are all ride apps there. Free public Wi-Fi often asks you to register first, so your own mobile data comes in handy when you need a ride.

### Does the Asia eSIM work in South Korea?

Yes, South Korea is on this 19-country eSIM. Many Korean apps ask for a local phone number to sign up, which a travel eSIM may not provide, but Naver Map and KakaoMap give walking and transit directions where Google Maps can't.

### Does the Asia eSIM include Australia?

No. Australia is on the 20-country Asia eSIM, not this 19-country one, and that version leaves out Taiwan, Uzbekistan, Laos, Bangladesh, Kazakhstan and Kyrgyzstan. Check which one you need before you buy.

### Is there 5G on the Asia eSIM?

Yes, 13 of the 19 countries on this eSIM have 5G, so check the networks for the places you're visiting. Your phone also needs to support 5G, and that's worth confirming before you buy.
