My card is broken. How can I find out why my card is broken?

Contact the operator's customer service to find out the cause of card damage. Specifically, you can check the reasons for your card break through the following steps:

1. First, confirm whether the shutdown is caused by card break. Before this, your mobile phone number may have received a text message or voice prompt to inform you that your mobile phone number has been included in the list of broken cards.

2. If it is confirmed that the card is broken, you can call the operator's customer service phone for consultation. According to China's relevant regulations, illegal mobile phone cards mainly include unregistered mobile phone numbers, forged ID cards and multiple mobile phone numbers. If your number is blacklisted, it will be suspended and you need to contact the operator for verification.

3. When consulting customer service, you need to provide your own identity certificate and mobile phone number for the operator to verify. In case of downtime due to non-real-name registration, it is necessary to go through real-name authentication and other procedures in accordance with local policies and regulations before resuming use. In short, if your mobile phone card is included in the list of broken cards, you can contact the operator's customer service to understand your specific situation and deal with it according to the corresponding policies and regulations.
