Registering for the eSIM was a bit confusing. I had to ask ChatGPT for help, sending screenshots and questions right before my flight took off – it was a really close call! I thought I understood it, and then the plane took off immediately. But the internet was good and fast, no speed reduction. They said this eSIM was good enough for concert ticketing, so I bought it. Sharing internet, sending photos, and videos was quick. However, it failed again when I entered the concert venue. After the concert, the internet was still dead. I had to go to a less crowded, more distant area for the signal to return. That was when I went to the BTS concert at Arirang.

Initially, I had trouble in connecting the eSim but once you go throuigh the layers, it was ok. I had no problem with this eSim and it was good to use considering my other physical SIM Card wasn't optimal for me. May consider using KT more in the future.
