I was able to use it comfortably, so I recommend it. I got the 100GB per day plan, but I only used LINE, maps, and store search, so I didn't actually use even 1GB per day (lol). It's also helpful that you can check your current usage. I'll use it again next time.

We had some problems with installing the e-sim, but trip.com customer service came to rescue and everything is good and well. Signal is good too.

I used the 10GB plan for 30 days. During the contract period, I changed the settings on my smartphone and lost signal, causing my connection to be cut off. It was past midnight Korean time, but thanks to Trip.com's staff's long operating hours, I was able to contact chat support immediately and the issue was resolved. The person in charge seemed to be in China or the surrounding area, and spoke Chinese, but thanks to the automatic translation function, I was able to communicate in my native language, which was very convenient. Thank you very much.

Activation was easy and the connection was stable. I was asked for my phone number at the hotel while I was in Korea, so I'm glad I reserved one with a phone number. Popular restaurants sometimes require a phone number for waiting, so I'll reserve the same one next time.

I ordered two eSIM cards. One for me and one for my wife. For some reason, the connection didn't work in China, which was disappointing at first. Then it turned out I needed to enable roaming in the SIM card settings (iPhone 17). And I got a connection in the Philippines. The reception is pretty good, you can even make video calls.

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.
