What SKT does

SK Telecom Co., Ltd. (SKT, KOSPI: 017670) is a South Korean telecommunications and AI infrastructure company headquartered in Seoul, founded in 1984 originally as Korea Mobile Communications. The company operates as a core subsidiary of SK Group, South Korea's third-largest conglomerate. SKT serves four primary customer segments: enterprise and industrial customers seeking integrated AI infrastructure, manufacturing and petrochemical sites deploying industrial robotics over AI-RAN, international tourists using e-SIM services, and global telecom operators licensing AI infrastructure technologies through channel partnerships.

SKT's product portfolio is anchored by its AI Pyramid 2.0 strategy. Core offerings include the Sovereign AI Package (integrating AI data center infrastructure with the proprietary A.X K1 AI foundation model and enterprise AI services), AI-RAN infrastructure enabling ultra-low latency industrial robot operations, and AI servers jointly developed with Arm (AGI CPU) and Rebellions (RebelCard accelerator chip). The technology stack includes AI data centers built on SK Group capabilities, AI-based radio access network technology achieving up to 10x higher transmission efficiency than 5G with approximately 18% improvement in data recovery accuracy and 30% reduction in data loss rate in millimeter-wave environments, and alignment with O-RAN and 3GPP standards under South Korea's government-backed AI Highway initiative.

SKT generates revenue across multiple streams: AI data center services (4% of Q3 2025 revenue, targeting KRW 1 trillion by 2030), enterprise AI services via the Sovereign AI Package, AI infrastructure and semiconductor-related supply partnerships anchored by a $750 billion five-year advanced memory semiconductor commitment with Nvidia and other global tech firms, and consumer telecom services including e-SIM offerings distributed through the Discover Seoul Pass partnership network of 219 facilities. Distribution is primarily direct enterprise sales complemented by strategic channel partnerships with global telecom operators (Deutsche Telekom, Orange Group, e& Group) and tier-one technology vendors (Nvidia, Arm, Ericsson, Nokia, Samsung, Rebellions). The company is publicly traded on KOSPI under ticker 017670.
