eSIM in Asia
Data does the heavy lifting on a multi-country Asia trip. You'll hail rides on Grab in Thailand, Malaysia, and Vietnam, check Tokyo train times between transfers, translate menus in Seoul, and keep the group chat alive on WhatsApp from a beach in the Philippines. Changing countries every few days only works when your data changes with you.
Buy your eSIM for Asia before you fly. The install link arrives by email — tap it at home and your phone sets the eSIM up itself, or scan the QR code if you prefer. Your data is ready when you land: no store visits, nothing to swap at any border.

Pick the coverage that fits your route
Sticking to Southeast Asia? The compact list covers hubs like Singapore, Thailand, and Vietnam. Adding Tokyo, Seoul, or Delhi? Choose a wider coverage option that includes Japan, South Korea, or India. Open each country list on this page and check every stop before you buy.
One eSIM, many borders
Flying Singapore to Bangkok, then on to Tokyo? Your eSIM reconnects automatically in each covered country. Skip the arrival-hall SIM counters and keep one data plan for the whole route.
Download offline maps first
Save offline maps before island hopping in Indonesia or the Philippines, or trekking in northern Vietnam. Signal fades on boats and mountain roads, and a saved map still gets you back to town.
Use Grab across Southeast Asia
Grab handles rides and food delivery in Singapore, Thailand, Malaysia, Vietnam, Indonesia, and the Philippines. One app and one account work in every city — it just needs data, which you'll have the moment you land.
Different map apps in Korea
Google Maps has limited features in South Korea, so locals use Naver Map and Kakao Map instead. If your coverage option includes South Korea, download both before you arrive in Seoul — they have English versions and make the subway far easier.
