Unicom prepaid the phone bill. How can I return or cancel this card?

If there is a contract, the account cannot be closed during the contract period. If you don't use it, your monthly rent and other expenses will be deducted as usual When your account balance is insufficient, it will lead to downtime arrears. After three months of downtime, China Unicom will generally cancel the account. Moreover, your ID card information will be pulled into Unicom's blacklist, which will affect your preferential business in the future and will result in a certain late payment fee or liquidated damages. It is also possible to receive the arrears notice from Unicom to settle the arrears. If you lose your contract machine, I suggest you report the loss first and reissue it in the business hall. According to the contract, if the machine card is separated, it will affect the return of your contract award. Regarding the handling method of contract award after the contract machine is lost, due to the different policies of each city, you can consult the local manual customer service or local business hall for details.
