Line is fast and reliable. Very affordable price for short trip. Activation took less than a minute. Once you landed you will have your line.

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.

The SIM card worked perfectly from the moment I inserted it. Fast and stable internet, good coverage both in cities and during trips. I had no issues with connection or speed, even when using maps, social media, and video calls. Very easy to activate, no additional setup required. Definitely recommend for travelers visiting Korea.

It's easy. I've had issues with cheap SIM cards in the past, but this one is genuine, so I feel safe. I was able to use it right away after it arrived, and there were no problems with the signal. So, although I don't know how the customer center will handle it, I'll definitely use their services again.

These eSIM cards are a great idea. No need to bother with buying physical ones anymore. Have you tried buying and registering a SIM card in the Philippines? Our friends tried, and it took a terribly long time. Overall, if your phone supports eSIM, I highly recommend buying it here. It's less hassle and cheaper.
