The SIM Reset solution preserves user data, such as financial certificates, T-money, and contact information, eliminating the need for re-authentication with financial institutions or resetting applications. Available for both physical SIM and eSIM users, it offers a convenient alternative to traditional SIM replacement. SK Telecom noted that the solution provides the same security benefits as a new SIM card but with greater ease of use, allowing customers to choose based on their preferences.
SK Telecom plans to offer the SIM Reset solution to customers visiting T World stores after receiving SIM replacement notifications, with potential expansion in the future. Starting May 12, when SIM card inventory increases, the company will enhance reservation scheduling for SIM replacements. Additionally, SK Telecom is improving access to eSIM self-activation to meet customer needs efficiently.
The company validated the SIM Reset technology in collaboration with the 6G Forum and the Open RAN Industry Alliance (ORIA), mobile communication research organizations, confirming its effectiveness ahead of implementation. Professor Kim Dong-gu, Executive Committee Chairman of the Open RAN Industry Alliance, stated: “This technology, which resets only authentication-related information through software without the inconvenience of backing up personal data in the SIM card and resetting the app, will be a useful technology in the future as the importance of security grows.” Similarly, Professor Jang Kyung-hee, Executive Committee Chairman of the 6G Forum, said: “This technology, which resets only authentication-related information through software without the inconvenience of backing up personal data in the SIM card and resetting the app, will be a useful technology in the future as the importance of security grows.”
The SIM Reset solution reflects SK Telecom’s commitment to enhancing user security and convenience in mobile communications. By leveraging advanced software-based technology, the company aims to protect customers from SIM-related fraud while streamlining the user experience. This innovation positions SK Telecom as a leader in addressing emerging security challenges in the telecommunications industry.
