GSM modem

A GSM modem is a device that enables electronic equipment, like computers or microcontrollers, to connect to mobile phone networks. It uses the GSM (Global System for Mobile Communications) technology to send and receive data, such as text messages or internet signals, much like a mobile phone does. Essentially, it acts as a bridge between a machine and a cellphone network, allowing automated communication without a phone. GSM modems are widely used in applications like remote monitoring, alert systems, and automated data collection, providing reliable wireless connectivity for various devices.
