Description
🔍 Product Overview
The SIM800L V2.0 module is a compact, integrated GSM/GPRS transceiver supporting quad-band networks (850/900/1800/1900 MHz). Designed for use in microcontroller-based systems, it offers voice calls, SMS messaging and data transmission over GPRS. With a built-in voltage regulator and TTL-level serial interface, it simplifies wireless connectivity in embedded and IoT projects.
🚀 Why It’s Ideal for Your Projects
-
Worldwide network support — Works across 2G GSM networks globally thanks to quad-band compatibility, making it ideal for international IoT and mobile applications.
