Planning to visit China, Japan, and South Korea in one trip? This classic East Asia route is incredibly popular — but each country has its own connectivity quirks. Here's how one multi-country eSIM solves them all.
Three Countries, Three Challenges
East Asia is a fantastic multi-country destination, but each country presents something to plan for:
- China — Google, WhatsApp, and Instagram are blocked on local networks
- South Korea — Google Maps is limited; locals use Naver and Kakao
- Japan — free Wi-Fi is patchy and you'll rely heavily on translation
The Solution: A Multi-Country East Asia eSIM
Instead of buying separate SIMs in each country, a regional eSIM covers all three on one plan. And importantly, our China-inclusive regional plans route through international connections — which means Google, WhatsApp, and your usual apps keep working even in China, no VPN required.
Why This Matters
The biggest headache for this route is usually China's app restrictions. With the right regional eSIM, you skip that problem entirely — you stay connected to Google Maps, WhatsApp, and everything else across all three countries, seamlessly, from the moment you land in each.
How Much Data Do You Need?
- 5 GB — a week or two of moderate use
- 10 GB — a typical multi-country trip with daily maps and apps
- 20 GB+ — longer trips or heavy use
What You'll Use It For
- 🗺️ Maps across all three countries (with Google working in China!)
- 💬 WhatsApp and messaging without a VPN
- 🚄 Navigating trains and metros in each country
- 📸 Sharing your whole East Asia journey in real time
