    Thanks to Klook and KT telecom, we received the simcard immediately after touching down Seoul. The sim was fast and convenient. We like it and will definitely buy it next time. Strongly recommended for those visitors who stay in Korea for a short time 👍

    Very fast data so it’s very convenient to travel around using KakaoMap. I was able to visit so many things in one day because of it. Plus, I was able to communicate with my family all day even though they live abroad. It was very easy to pick up as well, the staff was very nice!

    Pretty fast and reliable. I always buy sims from other countries when traveling especially if they have pretty good internet connectivity. An essential when traveling alone and you rely on maps. 😀 i just hope they update the name because the counter personnel got confused at first with regard to the sim name or network provider is correct.

    It was my first time booking for pick up at Gimpo airport, and I was not disappointed. As with Incheon, claiming of the sim card was quick and easy. KT's service is superb as always, keeping me connected, and enabling me to update and keep in touch with friends as I travel. Thank you so much Klook!

    i used klook for the first time for this trip and found that they have great prices and the vouchers are very easy to use. the sim card is so easy to use and collect. I bought it for my friends who were arriving in Seoul to meet up with me and accidentally ordered to pick it up the day after they arrive. I went to see if I could pick it up and there was no problems at all. the staff was also super friend when providing it to me. the network is very good and stable. no wonder Korea has the worlds fastest internet. we were to to enjoy the trip and upload our photos as we travelled.

    This is my 2nd time in Korea and I really didn't regret choosing Olleh. My data connection was really fast. My friends even asked me to do hotspot. I went to a lot of places, worry free because my data connection was really stable. thanks Klook!

    My Klook Driver help me to exchange my voucher to the KT officer. I thought I still have to go to Terminal 2 since in the instruction provided in the voucher, it is mentioned that the KT kiosk is open 24hrs on Terminal 2. I arrived at Terminal 1. Luckily, my driver at Klook, found a KT kiosk in Terminal 1. Im happy that I was able to get my Sim! Very fast internet connection. No delays and lags. Unlimited data is very useful specially if you are a solo traveler. Thanks Klook!
