Telecom cards will stop when they are overdue for a certain period of time. If the payment is not made after a certain period of time, the telecom card will be automatically cancelled. According to the regulations of China Telecom, after the cancellation of the telecom card, it can't be used for calling, surfing the Internet and other services, and a new card is needed.

If you need to restore the cancelled telecom card, you need to pay the arrears first, and then apply to the telecom customer service for restoring the card number. The cancellation of telecom card arrears will bring some inconvenience to users, so it is necessary to pay the arrears in time to avoid the cancellation of the card number.
