Common Questions
How can an eSIM help me explore Asia beyond the airport?
You walk into Haneda Airport’s arrivals hall and open Google Maps for the train route to Asakusa, passing the SIM counter queue instead of joining it. On the ride, you follow the station names and save a little noodle shop near Senso-ji. Outside the station, the map guides you through streets lined with lanterns and shopfronts; Google Translate helps you read the handwritten specials before you choose lunch.
You book a museum ticket on your browser, pay by card at the restaurant and send a photo of your bowl home. When your feet need a break, you use GO to request a taxi instead of trying to explain a pickup point across a busy junction. Back at your accommodation, you browse Uber Eats for dinner and use LINE to message a Japanese friend about meeting near the temple gate.
What should I look for in a tourist eSIM for Asia?
For a route through China, Japan and South Korea, look for one regional eSIM that covers all three, with local network access around major visitor routes. This Asia plan covers those countries, so you can keep the same eSIM as you move between them. Choose the package for its stated data allowance and validity.
Look for hotspot support if you share data with another device; it works on most plans. This plan also supports top-ups when you need more data. Preflight installation is available through the one-tap button in your order email, and you have 180 days from purchase to activate.
Where does the Asia eSIM have the strongest coverage?
The Asia eSIM covers China, Japan and South Korea through local networks including KDDI/au, SKTelecom, with 3G/4G/5G connectivity. Coverage is strongest in cities and main tourist areas such as Beijing, Shanghai, Tokyo, Osaka, Seoul and Busan. It becomes patchier in China’s mountain interior, Japan’s remote mountain valleys and outer islands, and South Korea’s mountainous national parks.
