There is abnormal use of your number card. What's the matter with receiving such a message?

If you receive a short message about the abnormal use of your number card, it may be because of the following circumstances:

1. Your mobile phone number has been maliciously attacked: it may be that someone else tried to crack your mobile phone account password, or tried to attack your mobile phone number in other ways, causing the system to issue a warning message.

2. Your mobile phone number was misjudged: It may be that your mobile phone number was misjudged as abnormal use, or the system made a wrong judgment for some reason.

3. Your mobile phone number is abused: If your mobile phone number is abused, such as being used for spam messages and fraud, the system may send a reminder message.

In either case, it is recommended that you immediately contact the relevant operators or customer service for verification. If the mobile phone number is found to be maliciously attacked or abused, measures should be taken as soon as possible to protect personal information and account security.
