The company operates in the telecommunications industry in Korea and other markets, providing services to mobile phone subscribers. In Korea, the competitive landscape includes three main mobile and fixed network operators: the company, KT Corporation (KT), and LG Uplus Corp. (LG U+). As of December 31, 2025, KT and LG U+ together held approximately 58.4% of the mobile phone subscriber market share, which includes 15.1% attributed to mobile virtual network operators (MVNOs) leasing networks from KT and LG U+. The company's market share in 2025 was adversely affected by a cybersecurity incident involving the leakage of USIM information of its 5G and LTE network subscribers.
