The (almost) 5-star eSIM
The eSIM was very easy to install and, once I reached my destination, I had a connection from the very first moment without having to worry about roaming.
Activation was quick and simple, and I had a connection the whole time with no hassle. Coverage and speed were very good.
I went on a trip around Latin America and had coverage everywhere, at a very good price. Highly recommended 💪🏼

More about the China, Japan, and South Korea eSIM
eSIM for China, Japan and South Korea: internet without roaming
With a single eSIM you get mobile data in all three destinations of the most sought-after Asian trip, without swapping cards when crossing borders or paying your carrier's roaming fees. Our eSIM runs on the real networks in each country: China Mobile, China Unicom and China Telecom in China; NTT Docomo, SoftBank and au (KDDI) in Japan; and SK Telecom, KT and LG U+ in South Korea. You land at Beijing, Tokyo or Seoul airport with internet active from the first minute.
Roaming in China, Japan and South Korea: why an eSIM works for you
None of the three countries are in the European Union, so your carrier's roaming charges skyrocket — it's easy to pay 10 or 15 € a day, or per-megabyte rates that ruin your bill. With the eSIM you pay once for the whole trip and forget about it. In China there's an extra advantage: our connection routes traffic outside the country, so you can use Google Maps, WhatsApp, Instagram or Gmail without needing a VPN, something that doesn't always work with a local Chinese SIM.
How much does an eSIM for China, Japan and South Korea cost?
Prices go up depending on the GB and days you need. For a one-week trip visiting one country, 3 to 5 GB is plenty if you use hotel Wi-Fi. For a two- or three-week circuit through all three countries, using maps, translator and some video, a 10 GB or higher plan is the comfortable choice. You can compare all options and pick the exact duration before paying.
eSIM vs physical SIM in China, Japan and South Korea
A physical SIM forces you to find a counter at the airport, communicate in another language and, in China, show your passport for registration. The eSIM is 100% digital: you buy it before leaving home, install it with a QR code and land with data ready. Plus you keep your usual number on the main SIM for bank SMS or calls, while the eSIM handles only internet.
Does the eSIM work in Beijing, Tokyo, Osaka, Kyoto, Seoul and Busan?
Yes. Coverage follows the major carriers in each country, so you get good 4G and 5G signal in Beijing, Shanghai and Xi'an, in Tokyo, Osaka and Kyoto, and in Seoul and Busan, as well as on high-speed trains like the Shinkansen or KTX and in the busiest tourist areas. You can see the full list of countries and plans at all destinations if your route includes any extra stops.
How do I activate the eSIM for China, Japan and South Korea?
After purchase you receive a QR code and instructions by email. You scan it from your phone settings, leave the eSIM installed and activate it when you arrive at your destination, once it connects to the local network. It's quick and you don't need technical know-how. If it's your first time, we explain it step by step in our eSIM guide, with screenshots for iPhone and Android.
