Hot search! Is canceling your phone number equivalent to betraying yourself? The truth is...

A few days ago, the topic "Canceling your mobile phone number is equivalent to betraying yourself" topped the Weibo hot search list, sparking heated discussion.

The topic originated from a popular science video recently released by a police officer named Xu Dudu from the Tongling Public Security Bureau in Anhui Province on his social media account. In the video, Xu Dudu said: "Canceling a mobile phone number is equivalent to selling out yourself. A casual cancellation of a mobile phone number is likely to cause financial losses. When a mobile phone number is no longer needed or you don't want to use it anymore, go to the business hall to cancel it. After a while, the operator will put the mobile phone number back on the market. The next person who uses your mobile phone number can use the mobile phone verification code to log in to your Alipay, WeChat and other software, and the consequences will be disastrous. You might as well take an extra step to unbind all the software bound to this mobile phone number, and make sure to change the mobile phone number reserved for the bank card, so that you can be foolproof."

Q: How long will it take for a cancelled mobile phone number to be put back on the market? Can new users still check the previous usage records of the mobile phone number?

A: The reporter called China Unicom's customer service hotline as a consumer, and the customer service staff said that if a user's mobile phone number is cancelled for more than 90 days, it cannot be retrieved. The cancelled number will indeed be put back into the "number pool", but the time of release is uncertain. In addition, after the mobile phone number is activated by a new user, the new user cannot query the payment details and other related usage records of the previous owner of the number.

China Telecom customer service staff said that according to national regulations, all numbers are recycled, but after a user's mobile phone number is cancelled, there will be a 90-day freeze period. After this period, it may be put back on the market. However, it is not yet certain whether it will be put back on the market in the future.

In addition, the telecom customer service staff said that if you want to check how many numbers you have in your name, you can search for "One ID Check" in the operator's app to check , or you can bring your ID card to the business hall to check, and you can also check the specific mobile phone number at the business hall. If you receive text messages from apps, websites, etc. that you have not registered with during the use of your number, you can call the customer service of the corresponding app, website, etc. for consultation.

China Mobile customer service staff said that there is a possibility that the cancelled mobile phone number will be put back on the market. If you receive a text message from an app or bank that you are not currently using for unknown reasons, please be vigilant and contact the relevant company or bank in time to inquire about your personal information.

Some operators have also launched a unified processing of registered number information on multiple Internet platforms. Taking China Unicom App as an example, you can find the service by typing "One Number Check" in the top search bar. The "One Number Check" service is a mobile phone number information sharing mechanism established by the number service promotion group between the number service platform, operators, Internet and other industry service units, and opened to users, that is, mobile phone number users can query Internet companies and applications that access the number service platform, and can apply to clean up the Internet applications that are not registered by themselves under the number, so as to improve the user experience in Internet application registration services.

Currently, it supports the processing of apps such as Weibo, Douyin, Toutiao, Meituan, Dianping, and Xiaomi.

Q: Is there a way to check the past binding services of a mobile phone number with one click?

A: The Ministry of Industry and Information Technology has launched the "One-card-check" function. Users can check the number of Internet accounts associated with their mobile phone numbers through the Ministry of Industry and Information Technology's official WeChat account "Gongxin Micro News", the Ministry of Industry and Information Technology's Anti-Fraud Task Force WeChat account, the China Academy of Information and Communications Technology WeChat account, and the Alipay "One-card-check" applet .

Q: How to use the “One-card-only search” function?

A: Open WeChat and search for the WeChat public account "Gongxin Weibao". In the "Government Services" column, click "One-card Check". After entering the homepage of the mini program, select "Internet Accounts". Follow the prompts to check the number of Internet accounts associated with your mobile phone number.
