KT announced on the 26th that it will provide 5G SA (StandAlone) service on an iPhone for the first time in Korea.

This time, 5G SA will be applied to five iPhone 17 series (iPhone 17, iPhone Pro, iPhone 17 Pro Max, iPhone Air, iPhone 17e), and SA mode will be available after completing iOS regular update (iOS 26.4). KT commercialized 5GSA service for the first time in Korea through Samsung smartphones in 2021.

5G SA is an advanced technology compared to the existing NSA (Non StandAlone) by providing services only with 5G networks without LTE network help. While NSA uses LTE network and 5G network at the same time, SA processes all signals and traffic in 5G network, which improves battery efficiency because it has a fast response speed and does not require LTE connection.

In addition, since services are provided only with 5G networks, more stable communication use is also considered a major advantage even in LTE network failures or disaster situations.

KT has been preparing for SA-oriented network evolution since the beginning of 5G commercialization in 2019, and has accumulated related technologies and operational capabilities by commercializing SA for the first time in Korea in July 2021 and commercializing 5G call service (VoNR) in October 2024. In line with the government's 5G SA transition policy stance, stable transition and service advancement are also continuously being promoted. Based on this technology and operational know-how, after cooperation with Apple and thorough network verification, the iPhone will also provide SA service.

Following the commercialization of VoNR, KT is continuously upgrading SA-based technologies such as network slicing (a technology that separates one physical core (core) network infrastructure into a number of independent virtual networks depending on the service type and provides customized services in each slice).

Kwon Hee-geun, head of KT's marketing innovation division (Sangmu), said, "We are continuously working to provide real 5G services that customers can feel," adding, "With the commercialization of iPhone 5G SA, we will provide the best service to customers amid the evolution of communication technology that leads to 6G."
