A "pseudo base station" is a pseudo base station. The device is a high-tech instrument, which generally consists of a host computer and a notebook computer. It can search the mobile phone card information centered on it within a certain radius through SMS sender, SMS sender and other related devices. By pretending to be a base station of an operator, you can arbitrarily use other people's mobile phone numbers and forcibly send short messages such as fraud and advertisements to users' mobile phones.
