I always get this kind of information recently. What happened?

I think the mobile phone number has been leaked. On the internet, no matter what you registered with your mobile phone number, the other company may disclose your mobile phone number in exchange for benefits (or the website is hacked and you can get your information). This is normal. Never pay attention to these harassing things, you don't know which is a virus and which is what. However, even if you block this number, the other party may send you text messages with other numbers, which is relatively risky, in case someone at home can't understand these letters.
