Because I was arriving late at night and planned to catch the last subway ride, I pre-configured my settings to turn off mobile data before departure to minimize the hassle at the arrival airport. Upon arrival, I connected to Wi-Fi at the airport and then switched mobile data on while waiting for immigration, and it worked immediately. I traveled outside of major cities as well, and the connection was excellent everywhere, making it very cost-effective. I would definitely use it again.
It was my 2nd time taking the KTX train from Busan to Seoul. The ride was very smooth. And along the way you get to see a glimpse of the various cities and towns of South Korea. Ample space to put your luggage. Ample leg room. Better than a plane ride.
