Recently, mobile phones always receive spam messages, not from 10086, and the number is very long, several times a day.

I guess your card is not in a regular place, or your mobile phone number was published when you were online, and then the people who sent the text messages were an alliance, and your number was on their list. You'd better change the number, or block it with an information firewall, or you can't stop their offensive. Or you can just report those mobile phone numbers, but you are very tired, and you have to send more than N text messages a day. Then you change the mobile phone of NB and filter them all out.
