    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!

    For me better to used sim card rather than pocket wifi because you don’t need to charge, carry power bank and will get internet connection at all area because sometime pocket wifi didn’t get coverage at certain area..

    I strongly suggest travellers to book this!!! We need this sim card! If you would like to post your photos right away and connect to your loved ones somewhere else, then you should definitely book this.

    Highly recommend this sim card, because roaming is extremely expensive in South Korea, but with such a sim card you could stay available by Internet always all over the country. I traveled around Korea by train and in each city I shared my emotions and photos on Instagram at once, chat with my friends and family on WhatsApp and used maps to check my destination online, very convenient!!!

    Hassle-free transaction with Klook yet again. Arrived at 1am in Incheon, good thing the redemption counter was open 24hours. Fast and reliable internet connection! Was able to tether my other devices too. Will definitely purchase again. Thanks, Klook!

    The 4G is fast and very reliable. Its my second time to purchase sim. And it never fails to amazed me. The speed of the internet wherever you are in korea is fast. Highly recommendable to get. So dont forget to grab yours when you visit korea! ♥️

    This is very useful and convenient. No need to charge additional device because it is a sim card. The domestic calls and texts also helped me especially when I applied to an event. The reception is also good anywhere you go. Internet is so fast. I am so happy with this item. This is highly recommended and worth it! I was able to update photos real time. See sample photos.

    I had another layover in Seoul/Incheon and decided to get a SIM card from here again, and I'm glad I did! Last time I picked up at Terminal 2 but did Terminal 1 this time, and the kiosk was just as easy to find as the other one. Data speed was super fast and was able to use as a wi-fi hotspot again. I got the 30 day SIM card for my mom too. I was able to find a KAL Lounge, enjoy a quick meal and check-out ICN a bit before my next flight!

    I bought 10 days unlimited data and it is really worth it! The internet is fast everywhere. It is very useful and you can search where ever you go. I've visited a lot of places. No more reason to get lost by using Google maps or Naver Map. Very good service! Thank you Klook!

    I had a 1-night layover in Seoul/Incheon and this was perfect for my needs! The kiosk is easy to find and the salesperson speak English well and had no problems getting the SIM card to work. Data speed was good enough for everyday web use. I also used it as a wi-fi hotspot for both my parents and it was great. And I think the 1 day SIM is good for 24 hours b/c I was still able to use it the next morning to find a lounge at ICN airport for breakfast and enjoy the view from the gate before my departure!

    My first solo trip to Korea and I knew I needed to get a sim card! I heard about Klook and it was very affordable for fast internet all around Korea. The booth to pick up your sim card was easy to find, once you get out to the main lobby you will see a bunch of booths for sim cards. I will definitely be using this sim card again the next time I visit Korea.

    I got it quickly at the airport counter, and the staff at the counter explained it in detail. I installed it on the spot. I also got two packs of instant noodles as a small gift. At present, it is very smooth to use. It is just right to use in places without wifi. You will also get a Korean number that can receive calls. The overall speed is very fast, and I will buy it again when I have a chance.
