SK Telecom is differentiating its 'AI for All' service by introducing an actionable agent that completes tasks like reservations and applications with a single phone call. Leveraging its telecom strengths, the company aims to expand accessibility to digital underprivileged groups by enabling AI use via phone calls. While rapidly expanding its user base through integration with A. (a service), SK Telecom is also optimizing computational resources to operate efficiently even with government-supported GPUs.

Kim Ji-hoon stated on the 16th, “What matters most in public services is providing a convenient and intuitive AI agent experience. We will utilize phone calls and text messages as AI access points so that even those unfamiliar with apps can use 'AI for All.'”

SK Telecom differentiates itself with an app-less environment where AI features available on apps/webs are accessible via calls. When users dial a special-purpose number, the AI agent recognizes voice commands to perform requests like taxi bookings or hospital reservations. As a shared access number, it is available to subscribers of other telecom providers.

Additionally, the agent can make calls on the user's behalf to verify information difficult to find through searches—such as wait times or room charges—and relay it. SK Telecom previously demonstrated a prototype linking its AI Call with the medical platform Goodoc to successfully book appointments.

Elderly users who struggle with app installations can use 'AI for All' via phone calls to hail taxis or request civil documents. Beyond the 20 consortium partners, SK Telecom signed MOUs with 11 additional companies, including Tmoney Mobility, which operates taxi and express bus reservation systems.

For public services, SK Telecom plans a proactive approach—alerting eligible beneficiaries first, unlike existing civil services that rely on applicant-initiated requests. Kim noted, “Expanding actionable services depends less on data volume and more on public API integration. We've requested the government to open more public APIs, and inter-ministerial discussions are underway.”

SK Telecom is reviewing plans to link with A. (Dot) to expand access points for 'AI for All.' To secure 5 million monthly active users (MAU) within the year, the company deems it necessary to integrate A.'s existing user base. The possibility of transitioning A. into a super app by pivoting it toward the 'AI for All' platform is also under consideration. Additionally, beyond short-term user acquisition goals, key performance indicators include task completion rates (from request to final execution) and revisit rates.

Operational sustainability will be achieved through optimized computational resource efficiency. As 'AI for All' aims to provide free AI access nationwide, the company plans to establish an efficient business structure via token optimization. SK Telecom is building a routing and orchestration system that allocates requests to lightweight or large-scale models based on task complexity, while collaborating with partners Nota and A2C2 to lightweight models.

Director Kim stated, “To ensure sustainability, we must continuously optimize token usage—reducing 100 tokens per request to 50 or 20. Our plan is to operate using government-supported resources without additional in-house GPU investments until next year.” The government allocated 512 NVIDIA B200 GPUs to three consortia this year and designated 1.7 trillion won (out of a 2.5 trillion won budget) for GPU leasing in 2025.

SK Telecom will launch a closed beta in mid-November and a commercial service in December. Director Kim emphasized, “Our goal is for 'AI for All' to become an agent that simplifies and executes daily tasks.”
