What should I do if I am insulted by mass texting?

In general, a regular group text message will have four words at the end: "Reply n to unsubscribe". First, in reply to these words, you can refuse to accept any short messages sent by this channel. Secondly, it seems that the letter number belongs to which segment of 106 information: 10655 Unicom, 10657 Mobile, 10659 Telecom, and the last two digits are the city code, that is, the city where the channel you use is located. There is also 1069, which is a triple play short message channel. Then you can call and complain or something. If the information received is from the mobile phone number, it can only be said that the other party sent the information in an improper way (issuing cards), and you can complain about this number. I hope it works for you.
