Send and Receive SMS in .NET using GSM modem

Send and Receive SMS in .NET using GSM modem – To send and receive SMS messages in .NET using a GSM modem, you will need to use a third-party library. Here is an example of how you could use SMS Gateway to send an SMS message in .NET. Install and configure SMS Gateway on your system. Connect your GSM modem to your computer. Add a reference to the SMS Gateway library to your .NET project.

To send and receive SMS in VB.NET using a GSM modem, you need to use the GSMComm library which is a .NET library for communicating with GSM modems. The library provides the necessary classes and methods to send and receive SMS messages from a GSM modem, manage contacts, read and write SMS messages from/to the SIM card, and more. To use the library, you need to first install the GSMComm library from the official website, then add the references to your .NET project. After that, you need to create a new object of the GSMCommMain class with the port name, baud rate, and timeout as parameters. Then, you need to use the MessageBox class to display a message box to the user to select the port name from the drop-down menu. Once the port is selected successfully, you need to press the connect button. If the port is not valid, then an error message will be displayed. Once connected, you can then use the SendMessage method to send an SMS message to a mobile phone. You can also use the ReadMessage method to read an SMS message from a mobile phone.
