What should I do if my mobile phone receives a lot of registration text messages? Will there be any danger?

Generally, there will be a sentence in the registration text message: "If it is not done by you, please ignore it. If you want to unsubscribe, balabala". My general habit is to unsubscribe immediately if it is not what I need. This will reduce the number of spam messages.

If you notice that this text message is always sent from a similar number, you can use the system or similar software to block the number or keyword (there is a certain risk, it is recommended to check the spam text messages regularly to see if there are no non-harassing text messages)

I have received a large number of similar text messages warning that your personal information may have been leaked. You should be careful not to leave your true information on unnecessary occasions and places.

Some personal experience, very Official, hope this helps
