Things to note when changing your mobile phone number
Mobile numbers are an indispensable part of modern life, and they are closely linked to our various accounts and services. However, when we need to change our mobile number, we often encounter some risks and hidden dangers. This article will provide you with comprehensive suggestions and guidelines on how to protect the security of your personal information when changing your mobile phone number.
1. The risk of "secondary release" after the cancellation of the mobile phone number
After the mobile phone number is cancelled, it will go through a 90-day freeze period, after which the operator will put it back on the market for new users to apply for. This process is known as "secondary release". This means that if the original account and service are still using the cancelled mobile phone number, the new user may log in through the SMS verification code. This will not only cause security risks to the original account, but may also lead to a series of property losses.
Therefore, before canceling a mobile phone number, it is important to thoroughly check and unbind all accounts and services related to the number, including but not limited to:
Financial applications such as bank cards and payment accounts
WeChat, QQ, Weibo and other social software
Personal information storage services such as network disks and cloud storage
Various membership accounts and subscription services
At the same time, it is recommended to back up important data such as mobile phone contacts and text messages before canceling the number to avoid the loss of contact information caused by the number change. Finally, it is also necessary to pay attention to the timely destruction of the SIM card to prevent it from being picked up and used by others.
2. Comprehensively inquire about the network account associated with the mobile phone number
Even if you haven't canceled your phone number, you should carefully check all the online accounts associated with the number before changing the number. The "One Card Check 2.0" service launched by the Ministry of Industry and Information Technology can help users quickly query the various Internet accounts associated with their mobile phone numbers.
Through this service, users can not only know the specific account information associated with the number, but also further query the detailed data such as the registration time and the last login time of each account. This helps to detect abnormal logins or unauthorized account bindings in a timely manner.
If there is a discrepancy between the query result and the information you know, you can further apply for "Unbinding and Detailed Query" and contact the customer service of the relevant enterprise for verification and processing. This not only maximizes personal privacy, but also avoids missing important account information when changing numbers.
3. Change the services associated with the mobile phone number in a timely manner
After ensuring that all accounts associated with the old number have been unbound and migrated to the new number, users also need to pay attention to changing the mobile phone number bound to various services in a timely manner. This includes, but is not limited to:
Financial accounts such as bank cards and credit cards
Alipay, WeChat Pay and other mobile payment platforms
Registered accounts on various shopping websites and apps
Social media accounts, such as Weibo, WeChat, QQ, etc
Personal information storage services such as network disks and cloud storage
All kinds of membership cards, subscription services, etc
For some important accounts, such as bank cards, payment accounts, etc., it is recommended that users not only change the bound mobile phone number, but also check the relevant transaction records in time to ensure the security of the account. At the same time, it is also necessary to pay attention to updating the contact information in other services in a timely manner to avoid communication barriers or information omissions caused by number changes.
4. Strengthen information security protections in the use of mobile phones
In addition to taking necessary protective measures when changing mobile phone numbers, users should also pay attention to information security protection at all times during the daily use of mobile phones. These include:
Be cautious about using public devices: Avoid using passwordless WiFi networks or public phone chargers in public places to prevent unencrypted information from being stolen from your phone.
Be cautious of accessing links from unknown sources: Be cautious about online tests, QR codes, SMS links, etc. from unknown sources to avoid being implanted with Trojan viruses.
Turn off the function of leaking information: In the chat software, pay attention to turning off the location sharing, automatic upload of contacts, and other features that may leak personal privacy. Pay attention to information security when posting updates.
Install apps correctly: Especially apps that involve sensitive information such as finance and payment, choose official channels to download, and set complex login passwords to avoid using easy-to-guess passwords such as birthdays and initials.
In general, in the context of today's highly developed information technology, mobile numbers have become an indispensable part of our lives. When changing the number, it is not only necessary to comprehensively sort out the various accounts and services related to the old number, but also to pay attention to the security protection of personal information at all times. Only in this way can we avoid all kinds of potential risks to the greatest extent and protect our privacy and property security.
