My China Unicom mobile phone card received a text message saying that it has entered the locking period, and all the phone charges I charged have been refunded. Is this card expired?

"Mobile phone number accounts generally have not been paid for a long time, or if the account is in arrears, the account will enter a recharge period. The recharge period is 90 days. If no payment is made during this period, the account will enter a locking period.

The lock-in period is 30 days. During this period, self-service payment is not supported. You need to bring your ID and card to China Unicom's own main business hall to consult for unlocking and payment. If the lock-in period exceeds 30 days and the payment is not processed, The number will enter the deletion period, which is equivalent to the account cancellation status and cannot be restored to normal use.
