SK Telecom plans to commercialize 5G Standalone in December 2026 after completing technology optimization and commercial network verification for the service (via rcrwireless.com).
5G-Advanced stays in test mode
The company is also studying and validating 5G-Advanced technologies and network elements. That leaves SK Telecom with one near-term launch target and another upgrade path still in evaluation.
Mobile revenue and ARPU both improved
SK Telecom reported quarter-on-quarter growth in mobile service revenue and ARPU in the third quarter. The company said it focused on attracting higher-lifetime-value subscribers rather than chasing aggressive subscriber growth, and it tied that approach to stronger profitability and customer value.
6G work sits further out
SK Telecom is participating in 6G research and standardization activities, with a 2029 standardization target and commercial deployment expected after 2030. That timeline keeps 6G well behind the company’s December 2026 5G SA plan and its current 5G-Advanced work.
Satellite competition remains limited for now
SK Telecom said low Earth orbit satellite services in South Korea are mainly used where terrestrial networks have limited coverage, including aviation and maritime operations. The company expects the impact on South Korea’s domestic mobile market to remain limited for now, while saying satellite operators would need more bandwidth and ground infrastructure to compete in the consumer market.
Droam Perspective
For mobile network buyers, the important signal here is sequencing: SK Telecom is putting a December 5G SA launch next to a slower 5G-Advanced review and a much longer 6G timetable. The revenue and ARPU gains suggest the carrier believes subscriber mix matters more than raw volume, which is consistent with its emphasis on higher-lifetime-value customers.
