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].

Core Viewpoint - The article discusses the upgrade of the "second number" service in China, allowing users to unlink their previous accounts from over 200 popular apps after acquiring a recycled phone number [1][2]. Group 1: Service Upgrade - The "second number" service has been upgraded to support one-click unbinding for over 200 commonly used internet applications, including WeChat, Douyin, Taobao, Meituan, Alipay, and JD.com [1]. - Users can submit unbinding requests, which are typically processed within five days by internet companies [1]. Group 2: Proactive Measures - Several telecom operators have initiated a "proactive renewal" bulk unbinding service to reduce risks associated with "second numbers" [2]. - China Mobile will push notifications to internet application providers about recycled numbers before they are reissued, ensuring unbinding is completed beforehand [2]. - China Unicom will also bulk解除前任机主与互联网账号的历史绑定关系 for numbers ready to be reissued, ensuring that the recycled numbers are "clean" [2]. Group 3: Limitations of the Service - The "second number" service only applies to unbinding accounts linked to previous users; current users must contact the internet application providers directly for their own unbinding needs [3].

工信部近日通告今年第一季度电信服务质量情况，其中提到要指导基础电信企业和互联网企业联合提供"二次号码焕新"服务，可一键解绑历史互联网账号， 目前已覆盖超200款主流互联网应用。 手机"二次号码"藏风险 专家指出，目前几乎所有的互联网服务都要通过手机号完成身份认证，手机号码已经成为互联网应用识别用户的主要标识之一。但是当手机号码被重新投放 后，如果原机主没有及时解除与各类应用、服务的绑定，新机主可能会通过短信验证码等方式登录原机主账号，引发个人信息泄露和权益受到侵犯等风险。 规范"二次号码"使用 或暴露个人信息 什么叫"二次放号"？为什么要重点关注"二次放号"的一键解绑呢？ 据了解，手机号码在被注销或者停用后，经过大约3个月的"冻结"，会被运营商重新投放市场供新用户使用。这种"二次放号"，本是盘活有限闲置号码资源 的常见做法，却有可能将用户的个人信息暴露于风险之中。 有使用"二次号码"的新用户发现，通过手机验证码，居然可以轻松登录前机主的应用程序账户；还有人时常收到陌生人的快递信息、购物平台的消费记录 等。 及时解绑原手机号互联网应用 保护个人信息 为什么要投用手机"二次号码"？使用"二次号码"需要注意什么？ ...
