Is it illegal to intercept short messages?

It is illegal to make pseudo base stations for SMS interceptors.

"Pseudo base station" equipment is a high-tech tool to implement telecom fraud. It is mainly composed of a host computer and a notebook computer. You can search the mobile phone card information within a certain radius, arbitrarily use other people's mobile phone numbers, and forcibly send short messages such as fraud and advertisements to users' mobile phones.

When this kind of equipment is running, the user's cell phone signal is forced to connect to the equipment and cannot connect to the public telecommunication network, thus affecting the normal use of mobile phone users. Whether the mass spam messages sent by pseudo base stations belong to the management of public security departments needs to be judged according to the content of the messages. If the content of short messages involves commercial advertisements, promotions and other behaviors, the behaviors of these enterprises should be managed by the industrial and commercial departments; If the content involves illegal activities such as soliciting prostitutes, swindling and reselling guns, the police will crack down on them according to law.
