SK Telecom announced on the 27th that it has secured first place in the mobile phone service category for the 29th consecutive year in the 2026 National Customer Satisfaction Index (NCSI) survey conducted by the Korea Productivity Center.

Since the introduction of the NCSI in 1998, SK Telecom has maintained the top spot every single year for 29 consecutive years—a record unmatched across all domestic industries.

The NCSI is an index that quantifies the level of satisfaction evaluated directly by consumers for products or services sold in Korea.

SK Telecom believes that its continuous recognition by customers over the past 29 years can be attributed to its efforts to improve AI-driven telecommunications services, its reinforcement of customer protection and network security following last year's cyber intrusion incident, and its ongoing activities to restore customer trust.

This year, SK Telecom has made "on-site communication" a core focus to rebuild customer trust. The CEO and other executives and employees are actively engaging with customers in the field to identify areas for improvement, applying these insights not only to products and services but also to customer touchpoints such as distribution networks and call centers. Since the beginning of the year, SK Telecom has also been operating the "Visiting Service," offering security and telecommunications education in 71 counties nationwide.

To further restore customer trust, SK Telecom has strengthened the role of its independent advisory body. The Customer Trust Committee, established in May last year, will continue to support trust-building initiatives under the principle of putting customers first throughout this year. Additionally, the company plans to expand the role of its 100-member customer advisory group, ensuring that feedback collected in the field is reflected in products, services, and overall policies.

Moreover, SK Telecom assessed that its efforts in customer protection—such as utilizing AI to strengthen network security and advancing spam and voice phishing blocking technologies—were highly evaluated. Last year alone, SK Telecom proactively blocked approximately 1.1 billion attempted telecom fraud calls, including voice spam and voice phishing attempts. The company is also enhancing customer experience by integrating AI into all aspects of its services and customer-facing channels.

Jaeheon Jung, CEO of SK Telecom, stated, "This year's achievement of ranking first in the National Customer Satisfaction Index is more meaningful and valuable than ever before," adding, "Without becoming complacent with the results, we will continue to carefully listen to even the smallest voices of our customers and pursue fundamental service innovations that customers can truly experience."

Meanwhile, SK Broadband was also ranked first for the 16th consecutive year in both the high-speed Internet and IPTV categories.
