What is an eSIM?

eSIM (embedded-SIM) is a virtual SIM Card that is embedded in a mobile device and can connect you to any operator in the world offering eSIM services.

The eSIM works the same way as a traditional SIM, but you don’t need a physical SIM card.

Experience the high-speed 4G LTE data provided by KT, the outstanding telecom provider in South Korea.

Different from the unstable roaming service, you could benefit from the stable and fast-speed 4G nationwide network.

From now on just simply scan the QR code, and enjoy the convenience of our eSIM service without worrying about losing your home country’s SIM card!

    Highly recommend KT. Activation was easy. Service coverage was never an issue around Seoul and Dae Cheon beach area, as well as the country side near Dae Cheon.

    Having one of these is an absolute must if you’re traveling to Korea. Excellent coverage everywhere including subway trains (tried in Seoul, Incheon, DMZ & Busan). Super easy to set up on your phone as well.

    I plan to visit Korea on 18th October, I have some question before I purchase it.
    1. Can use in Full south Korea ?
    2. Does it count from adding E-Sim to mobile, example I purchase on 6th Oct, and adding to Mobile on 18th Oct, so it count from 18th oct right ?
