In the present, as long as you use the mobile phone, the calling card is absolutely indispensable, although there is wifi, there is a WeChat phone, but once you leave the wifi, the mobile phone without the card is the "walking dead".
However, for many reasons, I don't want the current mobile phone card, or some of the arrears are too much, thinking of waiting for the mobile phone to stop for three months to automatically cancel the number.
In fact, some operators will automatically cancel after three months of overdue downtime of mobile phone numbers, but not all mobile phone numbers will be automatically logged off, and some numbers will not be logged off after downtime, but have been billed.
The mobile phone card is not cancelled due to the fee, which is very affecting the personal credit report and privacy security.
After the mobile phone is automatically cancelled, it will be recycled by the operator again until it is used by the next user, and then the problem comes.
When your previous number is activated and used by others again, the various website accounts or social accounts that you have registered with the number may be logged in by others, resulting in the possibility of privacy leakage.
Therefore, the safest way is to go to the business hall to handle the number cancellation, if you do not have time to run the business hall to handle, you can now operate on WeChat, just one operation can be.
Pay attention to the WeChat public account "Ministry of Industry and Information Technology 12300", and select "User Appeal" - "Submit Appeal" at the bottom.
Then follow the instructions to complete the operation and wait for the carrier to call.
Finally, it should be noted that when canceling an account, remember to unbind the relevant account binding!
