SIM 300 GSM MODEM

The SIM 300 GSM Modem is a compact quad band GSM GPRS communication module designed to add cellular connectivity to embedded systems and microcontroller projects. It enables SMS voice calls GPRS data and remote communication using standard AT commands through a simple serial UART interface.

Based on the entity reference SIM300 GSM GPRS module from the entity reference SIMCom this modem provides reliable mobile network connectivity and is widely used in industrial automation tracking systems and IoT applications. It can be directly interfaced with Arduino Raspberry Pi STM32 and other controllers.
