Core Viewpoint - The article discusses the challenges and solutions related to the "second number renewal" service, which aims to provide users with a "clean" mobile number free from previous ownership issues, highlighting the need for better coordination between telecom operators and internet platforms [5][12][14]. Group 1: User Experience and Issues - Many users face difficulties when trying to register new mobile numbers, as these numbers may have been previously active and linked to other accounts, leading to a "digital identity crisis" [3][5]. - The Ministry of Industry and Information Technology (MIIT) reported that by May 2025, the total number of mobile phone users in China is expected to reach 1.807 billion, intensifying the competition for number resources and prompting operators to recycle idle numbers [4]. - The "second number renewal" service, launched in May, allows users to unlink historical internet accounts from their new numbers, covering over 200 mainstream applications [5][12]. Group 2: Operational Challenges - The current "renewal" service primarily involves a one-way request from operators to internet platforms, leading to a lack of transparency and understanding of the processing results for users [7][9]. - Issues such as unstandardized processes and data interoperability hinder the effectiveness of the "second number renewal" service, raising questions about accountability among telecom operators and internet platforms [8][9]. Group 3: Recommendations for Improvement - Telecom operators should establish a rapid response mechanism to enhance service efficiency and transparency, ensuring users can track the progress of their requests [10][11]. - Internet platforms are encouraged to take responsibility for timely responses and efficient processing of unlinking requests, improving communication with telecom operators to streamline the process [11][12]. - Users should be empowered to authorize operators and platforms to handle unlinking matters, creating clear boundaries of responsibility to protect data and ensure compliance [12][13].
