What is a GSM modem?

A GSM modem is a hardware device that can provide you connection to a service provider. It requires a SIM card to work. It is mostly used to send out automated or bulk messages.

How sending SMS through a GSM modem works

This Autodetect option will detect your modem, and if it is connected right, the following window should show up with information about your connected modem and SIM card. You can check in this window that every detail is right with the hardware and the SIM card, just to make sure that you are using the proper hardware. Click the Ok button if you finished reading.
