South Korea's three mobile carriers will showcase their artificial intelligence business capabilities to the world at Mobile World Congress (MWC) 2026, which opens in Barcelona, Spain, on March 2, local time. Each company plans to build its presence on the global stage through a differentiated AI strategy.

According to industry officials on Monday, SK Telecom will share its "full-stack AI" strategy with global telecom officials under the theme, "SKT's AI that creates infinite possibilities." It will introduce its accumulated experience in operating AI data centres, related solutions and AI-based network technologies, including efforts to attract an Ulsan AI data centre and build the high-performance GPU cluster "Haein."

Visitors will see the "K-Sovereign GPUaaS (GPU as a Service)" solution that integrates offerings including the intelligent platform "AI DC Infra Manager" that monitors and manages integrated data across an AI data centre. It also includes the high-performance, high-efficiency cloud platform "Petasus AI Cloud," the GPU resource optimisation solution "AI Cloud Manager" and the real-time monitoring system "GAIA."

SKT will also unveil results from the government's next-generation AI model project. It will demonstrate at the venue the ultra-large AI model "A.X K1" with 519 billion parameters, which advanced to the second-stage evaluation of the Ministry of Science and ICT's "homegrown AI foundation model" project.

It will also display AI services that will serve as the brain, senses and eyes of physical AI. These include a digital twin platform that supports physical AI decision-making and planning, a robot training platform that helps physical AI learn the senses it needs, and the vision solution "SynapsEgo" that analyses first-person on-site video at high performance.

KT will set up an exhibition hall themed on "Gwanghwamun Square" and pursue a brand strategy that combines Korean identity with AI innovation. It will recreate iconic Gwanghwamun spaces in an immersive way, including the statue of King Sejong, KT's Gwanghwamun Building West and the Sejong Center for the Performing Arts.

At this year's MWC, it will present the enterprise AI operating system "Agentic Fabric" as its core solution. Agentic Fabric is an enterprise AI platform designed to perform tasks across corporate operations. It will also unveil "Agent Builder," which allows agents to be created and deployed based on industry-specific standard templates, and "Agentic AICC," which automates actual task processing beyond consultation. It will also exhibit "Vision Track," which searches for missing persons through AI video analysis.

It will also expand engagement with global visitors through content that combines K-culture with AI, including a K-pop dance programme, an AI hanbok experience and a cheering message from national soccer team player Kang-in Lee created with generative AI. KT also plans to set up an archive zone that highlights the history of Korean telecommunications technology to emphasise its identity as a leading domestic telecom company.

LG Uplus has set "people-centred AI" as its theme and will unveil "Ixi-O Pro," a future-oriented model of its ixi-O AI call agent. Ixi-O Pro is an AI call agent that comprehensively understands everyday data such as calls, text messages and schedules to proactively suggest context-appropriate information. It goes beyond simple recording to grasp conversational context and relationships and guide users to needed information.

It will also introduce an AI contact centre, an AI data centre, an autonomous network, the security solution brand IxiGuardian 2.0, a voice phishing prevention and response solution combining telecommunications and finance, and sovereign AI in cooperation with LG AI Research and Furiosa.

LG Uplus will also take part in the "Global AI Red Team Challenge" held during the event to verify the safety and reliability of generative AI. It will also unveil a real-time voice phishing response system developed with KB Kookmin Bank and promote the company's security technology to the world.

In particular, LG Uplus CEO Bum-sik Hong (홍범식) will be the only head among the three mobile carriers to deliver a keynote speech. Hong is set to present a vision for the full-fledged era of AI call agents under the theme, "people-centred AI."
