Why does my mobile phone always receive spam messages?

I guess you used your mobile phone to surf the Internet and went to some bad websites, or your card was useless in a regular place, so your relevant information was published. When I just surf the Internet with my mobile phone for a month, I often get some similar websites. You'd better change the number or use the information firewall to block it, and then send it to 10086999 for reporting, reporting the number+content, so that the relevant number will not appear.
