An SMS modem is a device that connects computers or other devices to mobile networks, enabling the sending and receiving of text messages in bulk. Similar to a mobile phone but designed for industrial use, it uses SIM cards and cellular networks (like 4G LTE, GSM, or WCDMA) to handle large-scale messaging tasks. It acts as a bridge between your system and mobile carriers, making automated, high-volume SMS communication possible .
