Do you know who was bombed by text messages? Can you call the police?

Of course. According to the Law of People's Republic of China (PRC) on Public Security Administration Punishment, SMS bombing is an act of disturbing public order, which is illegal. When calling the police, you can provide relevant evidence, such as the screenshot of the received message, the sending time of the message, the sender's number and other information, to assist the public security organ in investigation and handling. So, if you know who bombed by SMS, you can call the local public security organ.
