Is it illegal to send messages by SMS?

It is not illegal to send messages to others by SMS.

Whether texting is illegal or not depends on the specific situation. If the circumstances are serious, it is a violation of the public security administration punishment law, and the sender of the short message will be investigated for legal responsibility according to law, depending on the damage caused by the content of the short message to the receiver. If the short message content has caused serious physical and mental problems to the short message receiver, it needs to be solved through legal channels.

First, whether the short message content is illegal depends on the degree of harm to the short message receiver. If the circumstances are minor and have not caused serious harm to the message receiver, as a party, you can choose to call the police and ask the public security organ to give a warning. If the abusive content of SMS has caused serious physical and mental harm to the parties, sending abusive and threatening content many times after warning interferes with the normal life of the parties. If it involves insulting and slandering content, the sender will be investigated for responsibility according to law and bear corresponding responsibilities.

Second, don't delete abusive messages in a fit of pique, but you must keep the evidence. According to the constitution of our country, citizens have the right to personal dignity. If you are abused by SMS for many times, you must seek legal solutions and seek justice from the other party through legal means. Although there is no need for a lawyer to go to court, litigation is a complicated procedure. If there is no special reason, it is best to ask a professional legal person to solve it.
