SIM900 GSM/GPRS Shield for Arduino — add cellular SMS, voice calls and GPRS internet connectivity to your Arduino project in minutes. Supports quad-band 850/900/1800/1900 MHz. Just insert a SIM card and you're ready to go.

 

The GSM/GPRS Shield SIM900 (MPN: SIM900) is the fastest and most straightforward way to give your Arduino project full cellular capability. Built around the industry-proven SIM900 modem chip, this shield lets you send and receive SMS, make and receive voice calls, and connect to the internet over GPRS — opening the door to a wide range of IoT applications without complex wiring or external modules.

Κey Features

  • Quad-Band GSM/GPRS: Operates on 850 / 900 / 1800 / 1900 MHz bands → works with virtually every GSM carrier worldwide
  • SMS Support: Send and receive text messages via AT commands → ideal for remote alerts and monitoring systems
  • Voice Calls: Make and receive voice calls → enables interactive voice-response or alarm-call projects
  • GPRS Internet: Connect to the internet over GPRS → enables HTTP requests, cloud data logging and IoT device communication
  • Arduino Shield Form Factor: Plugs directly onto standard Arduino headers → no breadboard or soldering required for basic use
  • SIM900 Modem Core: Mature, well-documented chip with extensive community library support → faster prototyping and easier debugging

Compatibility

  • Arduino UNO / Mega / Leonardo: Designed as a direct-stack shield; communicates via hardware or software serial UART
  • Note for 3.3 V boards (ESP32, Raspberry Pi): The shield is designed for 5 V Arduino logic; use a level-shifter if interfacing with 3.3 V systems

Typical Applications

  • Remote sensor monitoring with SMS alerts (e.g., temperature, flood, intrusion)
  • GPS tracker projects that report location via SMS or GPRS
  • IoT data loggers that push readings to a cloud server over GPRS
  • Home automation systems controllable by text message
  • Emergency call or panic-button devices for personal safety projects

FAQ

Q: Do I need a special SIM card?
A: Any standard nano/micro/mini GSM SIM card from a local carrier that supports 2G/GPRS will work. Make sure data roaming or the GPRS service is activated on the card.

Q: Which Arduino library should I use?
A: The most popular choice is the GPRS Shield or TinyGSM library, both of which support the SIM900 chip and are available through the Arduino Library Manager.
