Management of SMS Messages with GSM Modem and C # Language in WPF

In this project a system with graphical interface in Windows Presentation Foundation was proposed and realized, which was written in C # programming language, in which the sending of text messages using the available GSM (Global System Mobile) networks is allowed, with GSM modems of different compatible brands that connect to these GSM networks, in order to carry out the process of sending text messages, without keeping record of it in the sending team, with a process in the simplest way possible, that allows to have a greater agility to increasethe productivity, all this from a Windows environment in which the text message must be entered and the telephone number to which the message will be sent and the result of this operation will be shown on the screen, in addition to allow the system to be portable, since it does not save configuration information.
