Frequently Asked Questions
Is there one eSIM for South Korea and Japan?
Yes. Besides plans for Korea only, this page lists South Korea and Japan plans and China, Korea and Japan plans, so a Seoul and Tokyo trip needs just one eSIM. In Korea, travel eSIMs use SK Telecom, KT or LG U+. Check the countries shown on each plan, and buy enough data for both legs of the trip.

Where can I get an eSIM in Korea?
SK Telecom, KT and LG U+ all sell prepaid eSIM plans to international visitors. A travel eSIM can also be bought online and installed before you fly, so it is already working when you land at Incheon or Gimpo and you can book a taxi or check train times right away.

Used this app for mobile data while in Malaysia for a few days last week. I rate it 10/10 for ease of use, affordability and for effectiveness too. After 5 days of regular usage, I still have 8GB left out of 10GB

It's truly excellent; you can get 24/7 support when you encounter a problem. It's the best e-SIM app.

This is the best part... A fantastic app. I had no problems during my week-long vacation in Paris, France. I used it on my Android phone and the setup was very easy with the QR code. The package prices are also much more economical compared to other e-service providers. Plus, you don't easily use up your internet data unless you're watching videos.
