What is the name of the device that receives the short message?

SMS cats, like the mobile phones we use, need the support of SIM cards. When you need to send and receive short messages, you can insert a mobile phone card that we usually use in the short message cat, plug in the power supply, and connect with the computer through the data cable (USB or serial port or network port), so that the function of sending and receiving short messages can be realized in the application management software of the computer.
