How to Get Your eSIM
- Choose Your Data Size
Select a plan that matches your trip length and data habits. A two-week backpacking circuit across four countries needs more data than a five-day business trip to one city. - Complete Your Purchase
Check out with your email address. Your eSIM QR code arrives instantly — no shipping, no waiting at customs. - Install Before You Fly
Scan the QR code in your phone settings while still on home Wi-Fi. Label the new eSIM profile 'Asia Travel' so you can find it easily. - Activate After Landing
Once you land in any of the 12 covered countries, enable data roaming on your eSIM line. Connection happens within two minutes. - Cross Borders Without a Second Thought
When you fly from Japan to Thailand or bus from Cambodia to Vietnam, your eSIM switches to a local partner network automatically. No new SIM required.
Traveler Tips
- Download offline maps for rural areas before crossing the Laos-Cambodia border — mobile signal can drop for 30+ minutes at remote checkpoints.
- Keep your home SIM in dual-SIM mode: incoming calls reach your regular number while eSIMno handles all data. Use WhatsApp or FaceTime Audio for outbound calls to avoid roaming charges on your home line.
- Install Grab before arriving in Southeast Asia — it works for rides and food delivery across Thailand, Vietnam, Malaysia, Singapore, Indonesia, and Cambodia with no extra app per country.
- At Changi Airport in Singapore, WeChat Pay and Alipay are accepted at most shops — but you need data to load your QR code, so activate your eSIM before leaving the arrival gate.
- The Japan Rail Pass must be purchased before entering Japan; JR ticket machines accept foreign cards but require data to confirm reservations via the SmartEX app.
- Crossing from Shenzhen into Hong Kong by MTR takes under 20 minutes — your eSIM will re-register to a Hong Kong network as you exit immigration.
Why Data Matters Across Asia
Asia rewards the connected traveler. In Tokyo, real-time translation apps turn kanji menus into English in under two seconds. At Bangkok's Chatuchak Weekend Market, Google Maps guides you through 15,000 stalls spread across 35 acres. In Shanghai, DiDi hails a ride to the Bund faster than waving down a taxi — but only if you have data to open the app.
Cross-border logistics depend on live information. Flight delays at Changi Airport push alerts to your lock screen. Boarding a Shinkansen at Kyoto Station? The SmartEX app stores your e-ticket QR code. Checking into a Bali villa? Airbnb's self-check-in instructions load only when you are online.
With eSIMno plans for Asia, your data pool carries across all 12 covered countries. Use 2 GB exploring Angkor Wat, another 1 GB navigating Kuala Lumpur, then stream a video call from a Melbourne café — no top-up, no SIM swap, no carrier hunting. Pick the plan size that fits your itinerary and focus on the trip, not the logistics.

Top Countries in Asia
Your Asia eSIM covers 12 countries, each with its own draw for travelers. Here are five marquee destinations where reliable data makes all the difference.
Japan
Japan runs on precision — and so should your connectivity. Scan QR codes at JR ticket gates, translate ramen menus in Osaka, and stream Sumo highlights from your Shinjuku hotel. Data keeps the trip on schedule.
Thailand
From the Grand Palace in Bangkok to the limestone cliffs of Krabi, Thailand blends culture and coastline. Grab handles airport transfers; Google Maps navigates night markets. Your eSIM balance works the same in Chiang Mai as it did in Phuket.
China
The Great Wall, the Terracotta Army, Shanghai's skyline — China demands data for translation apps, ride-hailing, and mobile payments. One eSIM means no scrambling for a local SIM at Beijing Capital Airport.
Australia
Sydney Harbour, the Great Barrier Reef, and the Outback cover a continent-sized country. Australia pairs well with multi-stop Asia itineraries; fly into Melbourne after Southeast Asia and your eSIM keeps working.
Cambodia
Angkor Wat alone draws over two million visitors a year. Cambodia rewards early risers who photograph the temples at dawn — and upload the shots before breakfast. Your data crosses the border from Vietnam or Thailand without a hitch.
Grand Palace, Bangkok
Getting Around Asia
Asia's size rewards travelers who mix transport modes. Budget airlines like AirAsia, Scoot, and Jetstar connect Bangkok to Bali in under four hours for a fraction of full-service fares. Book one-way legs to build a flexible route across multiple countries.
Rail Networks
Japan's Shinkansen links Tokyo to Osaka in 2 hours 15 minutes; the Japan Rail Pass covers unlimited travel on JR lines for 7, 14, or 21 days. In China, high-speed trains run from Beijing to Shanghai in 4 hours 30 minutes. Taiwan's THSR cuts Taipei to Kaohsiung to 90 minutes.
Land Borders
Overland crossings open Southeast Asia to backpackers. The Poipet border connects Bangkok to Siem Reap by bus in 8 hours. The Friendship Bridge links Vientiane, Laos to Nong Khai, Thailand. The Johor-Singapore Causeway sees 300,000 daily crossings — trains, buses, and private cars all queue at immigration.
Ferries and Island Hops
Ferries link Singapore to Batam, Indonesia in 50 minutes. In Thailand, catamarans run from Phuket to Koh Phi Phi in 2 hours. Malaysia's Langkawi connects by ferry to Penang and southern Thailand.
Whichever route you choose, your itinerary can span half a dozen countries in a single trip — and your eSIM follows along without a pause.

Yes. The eSIM registers to a local partner network in each covered country. Fly from Tokyo to Bangkok, bus from Cambodia to Vietnam, or ferry from Singapore to Indonesia — your plan stays active and your data balance carries over at every border.
Nothing manual. When you land in a new country or cross a land border — for example, the Poipet checkpoint between Thailand and Cambodia — your phone detects the local network and switches automatically. Keep data roaming enabled and the handoff takes under two minutes.
This plan covers 12 countries across Asia and the Pacific. The full list appears in the Countries Covered section on this page, directly below the plan cards. Scroll down to confirm every destination on your itinerary is included before you buy.
Yes. Keep your home SIM active in dual-SIM mode. Incoming calls reach your regular number over your carrier's network. For outgoing calls, use WhatsApp, FaceTime, or Google Meet over eSIMno data — this avoids roaming voice charges on your home line.
Purchase an additional eSIMno plan and install a second profile. Many travelers buy a backup plan before crossing from Japan into Southeast Asia, where video calls and navigation can drain data faster than expected.
The eSIM connects to 4G LTE or 5G networks depending on local infrastructure. In central Tokyo, Seoul, and Singapore, speeds routinely exceed 100 Mbps. In rural Cambodia or remote parts of Indonesia, expect 10-30 Mbps on 4G — enough for maps, messaging, and video calls.
An Asia eSIM eliminates the hassle of buying separate SIM cards in each country you visit. With one plan covering 12 destinations — from Tokyo to Bangkok to Sydney — your mobile data activates the moment you land and stays active across every border crossing. Install before departure, enable airplane mode for your flight, and switch on data roaming when you touch down in any covered country.
Cross-border travel across Asia puts real demands on your data. Translate Japanese train announcements in Osaka, navigate the backstreets of Siem Reap, video-call your team from a Shanghai hotel, then check into your Melbourne Airbnb three days later — all on the same eSIM balance. Your data pool does not reset at immigration; it follows you from country to country until your plan expires or runs out.
This multi-country eSIM suits backpackers circuiting Southeast Asia, business travelers covering regional offices in a single trip, cruise passengers docking at five ports in ten days, and families on guided tours spanning three or four nations. Pick the data size that fits your itinerary, skip the queue at every airport SIM counter, and keep your home SIM active for incoming calls via dual-SIM mode.
