I picked up the LG U+ SIM card at the airport and it worked right away after installation. The connection was fast in Seoul and also stayed stable during my day trip outside the city. Maps, messaging, and video calls all worked smoothly.

This SIM card was very convenient for my Korea trip. The staff helped me activate it quickly and the data speed was strong in subway stations, cafes, and shopping areas. I also liked having a local number for reservations.

The pickup process was simple and the SIM started working without any complicated setup. Internet speed was good for social media, Google Maps, and checking travel information. It was a useful choice for a short visit to Korea.

Picking up the SIM card at Incheon Airport was smooth, and I was very happy that the staff helped me with the entire exchange process. The signal and speed were fast, and although there were times when I couldn't connect on the subway, everything else was perfect!

Excellent as always!!! I always buy LGU when I come to Seoul because it's stable and reliable~ I even recommended it to my friends, hehe! I picked it up at the counter at Gate A of Terminal 1, and the lady at the counter spoke a little bit of Chinese! And after removing the SIM card, the pink card is the Tmoney bus card, so you don't need to buy a separate bus card!

The LG U SIM card I ordered from Trip.com worked perfectly. The counter was easily visible after exiting customs. The staff were friendly and helpful in replacing the SIM card. Throughout my Busan trip, navigation and mobile signal were consistently fast and convenient. The T-Money card was also very convenient; after topping up, I could use it on the MRT, Gimhae Airport MRT, and buses.

I've been using this phone card for a while now; the internet speed is fast, and it's easy to get one. I'll definitely use it again next time.

This was my first time trying a local Korean data SIM card, and I was surprised how convenient it was. Getting the SIM card at the airport was quick, and the Korean staff even helped me install it ? they were incredibly kind and helpful, and even gave me a SIM card ejector tool and a card holder. It worked immediately after I inserted it into my phone, and my personal transportation card worked instantly when I topped it up at the subway station. On the day I went to KSPO DOME, it was incredibly crowded, and several people around me said they couldn't send messages, but my friend and I (both using iPhones) had no problems at all. What I was most satisfied with was that I didn't even need to connect to the hotel Wi-Fi for several days; the data usage was consistently stable, and I could easily browse navigation and Instagram. Overall, the experience was much smoother than I expected, and I'll probably continue using this SIM card next time I'm in Korea. I recommend buying it online in advance; buying it directly at the airport is a bit more expensive.

Overall it was a smooth experience. The connection was fast enough for maps, browsing, and sharing photos, even when I moved between Seoul and Incheon. I would use this LG U+ SIM again on my next trip.

I used it for navigation, translation, taxi apps, and uploading photos every day. The LG U+ network was reliable almost everywhere I went, including Busan and Seoul. Much easier than looking for Wi-Fi all the time.

The SIM card gave me stable data during my whole stay. I used Naver Map, translation apps, and Kakao services without issues. Activation at the counter was quick, so I could start using it right after arrival.

Very reliable SIM card for traveling in Korea. I did not have to worry about finding public Wi-Fi, and the local number was helpful when I needed to confirm reservations. The airport pickup was also well organized.
