What hardware is needed to send an SMS from a computer?


I have a Windows 10 desktop computer (with no SIM card) with a program installed that lets me send an SMS message when a certain event fires [...].

The program lets me choose my COM1 interface as the output interface for the message.

What physical hardware would I need to send an SMS from the desktop computer?


Solution

  • A GSM modem. In the '90s I had a mobile phone that could act as one over a serial port.

    Today, to programmatically send SMS, most people will use a web service (such as Amazon SNS or Twilio MessageX) instead of dedicated hardware.
