Is it illegal to deactivate the cancellation number of telecom cards? What should I do?

This situation is not illegal. The solution is as follows:

1. If the operator closes down, he can only go to the local direct business hall to consult about restoring the machine. If the machine can be restored, he needs to sign anti-fraud notice and live video authentication.

2. If the network is disconnected locally, you need to consult the local public security bureau and other relevant departments, and submit relevant information as required to unblock it. This situation can not be solved by ordinary operators.
