It covered my whole trip from Seoul to Busan. Albeit, there are times that it got slow. The convenience and the efficiency it brought me makes up for it. I already tried this with my Japan trip and it worked amazing and fast. That's why I availed again this time for my Sokor trip. I'll avail again in my next international trips since it's cheap and very worth it!

I had a great experience using the 5G eSIM for South Korea that I bought from Klook. Setup was super easy—I just scanned the QR code and was connected within minutes, even before leaving the airport. The connection was fast and reliable throughout my trip, especially in cities like Seoul and Busan. I was able to use Google Maps, social media, and messaging apps without any issues. The 5G speed was noticeable, and I didn’t experience any major lag or disconnections. I also liked that I didn’t have to remove my physical SIM, so I could still receive important messages from my home number. Plus, it saved me the hassle of finding a SIM card or pocket WiFi after landing. Overall, it’s very convenient, affordable, and perfect for travelers. I would definitely use this again on my next trip to South Korea. Highly recommended!

Setup was so easy—I just scanned the QR code at home before my flight, and the second we landed, I turned the line on and instantly had full bars. The 5G was incredibly fast. I was using Naver Maps constantly, translating things on the spot, and uploading videos to social media with zero lag, even deep underground in the subways.
