Korea Cable Telecom

Korea Cable Telecom Co., Ltd. (KCT; Korean: (주)한국케이블텔레콤) is a South Korean telecommunications company and a facilities-based telecom operator (기간통신사업자). It was established on 23 August 2006 and is part of Taekwang Group. The company operates as a virtual mobile network operator (MVNO) and provides internet-based telephony, international calling, representative-number services, business communication solutions, and budget mobile plans under its Tplus (티플러스) brand. KCT's service portfolio is built around four main areas: internet telephony (인터넷 전화), telephony add-on services (전화부가), business solutions (비즈솔루션), and mobile (모바일). Its internet telephony offering provides low call rates over IP networks, designed to match customer scale for efficiency and convenience. Add-on services include a range of value-added telephony features backed by 24/7 customer support. Business solutions are tailored communication packages for corporate needs. On the mobile side, KCT offers budget plans that let customers keep their existing devices and call quality while paying at least 30% less, marketed as an honest service. The company has expanded its MVNO business through partnerships with major South Korean carriers. It launched SKT-based budget mobile service in 2011, added KT-based service in 2018, and began LGU+ network service in 2022. It participated in the Korea Post budget phone sales program in 2019 and introduced the country's first eSIM service for budget phones.

The company positions itself as a differentiated digital communication service provider built on leading technology and continuous customer-satisfaction management. Its corporate identity emphasizes communication genes and a joyful, open communication space, while its Tplus brand identity uses connected 't' and 'p' speech bubbles to symbolize dialogue and connection.
