The telecom card has reserved the disassembly order. Can it still be used?

the telecom card can be used after the disassembly order is reserved. Only the function of this mobile phone number is stopped, but the mobile phone number of Telecom can be used. The scheduled disassembly of the telecom card is the time to make an appointment to cancel the mobile phone card number. After going to the business hall to make an appointment for disassembly, the consumer can't use the telecom card to make an appointment for disassembly after the mobile phone card number. I bring my ID card to the business hall for formal disassembly, and the telecom card can be used after making an appointment for disassembly order.
