It's very convenient to use, communication is smooth, connections are always stable, and you can even share the network. It offers generous data allowances at an affordable price—highly recommended.

Reviews: South Korea | 4G eSIM | 1-30 Days | Daily Package / Total Package | Qecode
Guest User2025-10-09
I’m totally obsessed with this Korean eSIM! Before, when I carried a Wi-Fi egg, it would always lose signal when I was squeezed into the subway in Myeong-dong. I even lost a SIM ejector tool once when switching to a physical SIM card—such a hassle. But this time, I chose KT Telecom’s eSIM, and it totally unlocked a seamless internet experience. I received the email with the QR code just 3 minutes after placing the order. After scanning the code on my iPhone, the activation was done in 1 minute.

I used it in Ulsan, Pohang, and Busan, and the signal was good everywhere, which was great 😊 I was a little worried because I had to authenticate after arriving at Gimhae Airport, but I was glad I could authenticate without any problems once I connected to the airport's Wi-Fi 😊 I went not only in the city but also to the suburbs, and I had good signal reception in the East Sea side of Ulsan and Pohang, as well as Gwangalli and Haeundae in Busan 😊
