Why does Unicom's mobile phone number become empty?

Take Chongqing Unicom as an example: there are two situations in which the mobile phone number prompts an empty number.

1. The user has gone through the formal account cancellation procedures, and the mobile phone has gone through the formal account cancellation status. At this time, the mobile phone number will prompt the empty number.

2. If the number is in arrears for 3 months or more, the number will be recycled by Unicom to cancel the account, and the mobile phone number will also prompt the empty number at this time.

Tips: If you need to continue to use this number, you can wait for the number to be resold before applying for it.
