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.

Does a South Korea eSIM come with a phone number?
Most travel eSIMs, including most South Korea plans, are data-only and have no local number. You keep your usual number on your main SIM for calls, texts and WhatsApp. Plans that include a number or minutes say so on the plan page.

I bought the eSIM for a holiday in Tibet. Everything was great; with the integrated VPN I was able to access all the sites that are normally blocked in China (Google, WhatsApp, etc.).

This was my first e-SIM experience, and believe me, the signal is much better than the lines in Turkey. I traveled to four different cities in Indonesia and got 5G in all of them. 5 GB of internet lasted me three weeks. Thank you.

After 2–3 years of using the service, I encountered a problem for the first time. I can only praise the excellent technical support, which responded very quickly and with whom I exchanged several emails until the final resolution. Professionalism at its best!
