Land at Singapore's Changi Airport or Tokyo's Haneda, tap the install link Lumbus emailed you — your phone sets the eSIM up itself — and you're online before you reach baggage claim. This Asia eSIM covers 21 Asian countries on a single plan, so a trip that strings together Japan, Thailand, and Vietnam needs just one setup — no airport kiosk lines and no plastic SIM swaps at every border. Up to 10x cheaper than roaming with plans starting at $4.99.

Data does the heavy lifting on an Asian itinerary. You'll open Grab to hail rides in Singapore, Kuala Lumpur, and Manila, use Naver Map to navigate Seoul, translate menus in Osaka, and message home on WhatsApp from a beach in Bali.
Buy your eSIM for Asia before you fly, install it with one tap from the link in your email — or scan the QR code if you prefer — and it keeps working as you cross between covered countries. Your phone simply picks up a local connection in each one.

Practical advice for using mobile data in Asia.
Set up your eSIM on home WiFi before departure. Land at Changi, Incheon, or Bangkok's Suvarnabhumi, turn on data roaming for the eSIM line, and you're connected without touching an airport counter.
Grab handles rides and food delivery in Singapore, Thailand, Malaysia, Indonesia, the Philippines, and Vietnam. One account works across all of them, so keep the app installed as you hop between countries.
Google Maps offers limited directions in South Korea. Download Naver Map or Kakao Map before you arrive in Seoul, and save offline map areas for Japan and Vietnam while you're at it.
Signal gets patchy on ferries and in remote corners of Indonesia and the Philippines. Save offline maps of Bali, Palawan, or any island stops before leaving the city, so you can navigate when coverage drops.
Cross the causeway from Singapore into Malaysia or fly from Bangkok to Hanoi, and your eSIM reconnects to a local network on its own. No new SIM, just keep data roaming switched on.
