It was easy to book on Klook. Redemption was also easy, taking only about five minutes of my time. The counter can be easily found right out of the arrival hall in Terminal 1 at Incheon International Airport. The staff was friendly, and the process was almost seamless. Although the price can be on the steeper side, it does provide you with a Korean phone number, which is important for taxis or reservations.
This is always my go to for way to have a esim for South Korea. I have used the service a lot of times and its always reliable. This is from a local telco LGU so its fast and reliable. The included text and phone service is a must!
The LG u+ eSIM has never let me down. You have signal everywhere, and there are plenty of free Wi-Fi hotspots in different cities across South Korea.
This was an excellent one. The Data was so fast and efficient. The staff also assisted us in our esim. It was a hassle free experienced. Thanks Klook

Very easy to set up, just scan the code and wait for the installation! the internet is very fast and stable, highly recommended!
Arrival was quick. The guy who helped us set up the SIM cards and made sure to check that everything was working properly, both the internet and the calls. He also gave us T-money cards with a very adorable logo. I recommend it 100%!
Easy to use. Good network. I went to the airport stall and got a free t money card as well.
Its my 2nd time purchasing this e-sim for my korea trip but this time i added the plus of having a sms number and it was wonderful! it helped us a lot with reservations at popups and overall we had a great experience with the internet! I had no trouble using the data on seoul, incheon and busan. even on the subways the signal didnt get lost!
Easy to claim at the airport, and they will help you activate the eSIM. The data connection is stable, even in the subway.
