I used an eSIM while traveling in South Korea, and overall it was a very convenient and hassle-free experience. The setup process was quick and easy. I simply scanned a QR code before arriving, and the eSIM was activated within minutes. There was no need to visit a physical store or swap out my SIM card, which saved a lot of time, especially after a long flight. In terms of performance, the connection was generally fast and stable. I had good coverage in major cities like Seoul and Busan, including inside subways and buildings. Internet speed was more than sufficient for navigation, social media, and even streaming. One of the biggest advantages was the flexibility. I could choose a data plan that suited my trip duration, and there was no need to worry about topping up frequently. It also allowed me to keep my primary SIM active for receiving messages. However, there were a few minor drawbacks. The price can be slightly higher compared to local SIM cards, and if your phone battery
