What should I do if my mobile phone number is useless for more than 3 months?

The mobile phone number has expired and cannot be retrieved.

The mobile phone number has expired, that is, this number has been cancelled, and it cannot be replenished during resale.

When the arrears begin, the mobile phone number will be deactivated, and when dialing, it will prompt that the number has expired. At this time, the account has not been cancelled, and the arrears can be recovered.

After the number has expired for 3 months (6 months in some areas), the arrears are still unpaid. If you move, you will take back this number, which is equivalent to canceling the original number and reselling it.

Of course, an empty number means that no one has used it yet. You can try to communicate with mobile and buy the number again, provided that the arrears have been paid.

"Outdated" Chinese vocabulary. It often means that the food has passed the safe consumption period. Or refers to articles that have exceeded their safe service life. This may also mean that contracts and commitments have exceeded the set time.
