KT vs TIMB Comparison

KT is South Korea's largest fixed-line telecom operator, with around 11.5 million fixed-line broadband customers and 9.5 million IPTV customers, and is the second-largest wireless operator with 28 million subscribers. Additionally, it has a number of nontelecom businesses, including real estate, payment processing, artificial intelligence, and IDC/cloud services, many of which are the focus of its growth strategy. The company was formed from the previously government-owned, monopoly telecom business and was listed in 1998. After selling its mobile business in 1994 (forming its mobile competitor, SK Telecom), KT created its own mobile operator in 1997.

TIM, which is 67%-owned by Telecom Italia, is the third-largest wireless carrier in Brazil, with 62 million subscribers, equal to about 23% of the market. The firm owns 49% of I-Systems, an infrastructure partnership that is expanding its network footprint across Brazil. I-Systems can provide broadband service to about 8 million locations, including 6.5 million with fiber, equal to 10%-15% of the country. TIM leases capacity on the venture's network to serve retail broadband customers under the UltraFibra brand, but it has agreed to buy out its joint venture partner in 2026 and will take full ownership of these assets. TIM also resells fiber network access from other providers.
