On September 4, 2026, SK Telecom initiated an all-out effort to stabilize its mobile communication network ahead of the Yeouido fireworks festival, deploying AI and 5G technology, additional equipment, and dedicated personnel to manage an anticipated crowd of 1 million people. Earlier that day, SK Telecom increased its R&D expenditure and its R&D as a percentage of revenue in the first half of the year, signaling a focus on AI investment. This move followed its selection for the government’s "sovereign AI foundation model" project. The company, as part of a consortium alongside KT Corp. and Kakao Corp., also unveiled its blueprints for the government-led "AI for All" project, which aims to develop artificial intelligence services accessible to everyone. Previously, on September 4, Naver Cloud won a government project to develop an AI foundation model specialized for cybersecurity, a project in which SK Telecom also competed. South Korea had earlier detailed its "AI for All" initiative, with the three consortia preparing general-purpose chatbots and agents capable of carrying out daily tasks through various digital platforms.
