This offer showed up when I was making order reservations on klook. I was surprised at how much cheaper it was than e-Sims I used from different sources and considered buying for this trip. I checked terms and conditions and it matched what I wanted perfectly. I had no issues getting mobile data anywhere in Korea and we have travelled outside of Seoul. Extremely easy to download and install I will definitely consider looking on clock for the next time I travel and need an e-Sim.

Simply perfect, buy it without hesitation! It never let me down at any point, working perfectly absolutely everywhere I went, even inside the subway! I arrived in Korea already connected while still on the plane because I activated it before leaving home, and I stayed connected until I left the country, truly excellent 💗

Super convenient and reliable!I recently used the SKT 5G eSIM during my trip to Korea, and it was incredibly easy to set up, just scanned the QR code and I was online in less than two minutes. The connection was stable everywhere I went, from Seoul to Busan, and the speeds were consistently fast for streaming, maps, and messaging.The unlimited data plan was perfect for a 7‑day stay, and I didn’t have to worry about topping up or finding Wi‑Fi spots. It’s data only, but apps like Facebook and Instagram made communication seamless. Overall, it saved me time, money, and hassle compared to buying a physical SIM. Highly recommended for travelers who want a stress‑free, reliable connection in Korea.

I had a fantastic experience using Klook for my trip to Seoul. I purchased both an airport transfer and an eSIM, and everything worked exactly as promised. The eSIM was incredibly easy to install before my flight, and it activated without any issues when I arrived in Korea. I had reliable, fast data throughout my entire trip, which made navigating Seoul, using translation apps, finding restaurants, and calling rides completely stress-free. Having a dependable connection from the moment I landed made a huge difference. Klook also made travel simple with a smooth airport transfer, so from arrival to departure, everything was convenient and hassle-free. Overall, Klook helped make my Seoul vacation much easier, and I wouldn’t hesitate to use their services again on my next international trip. Highly recommend for anyone traveling to South Korea!

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.
