"KT has made a lot of effort in preparation for three years, including building a network of over 11,000 kilometers for the Olympic Games," said Lee Kang, managing director of KT Pyeongchang Winter Olympic Games. I hope the Olympic Games will be as successful as the efforts of the employees who have failed to get home even during the holidays. "
