The Arduino GSM Shield allows an Arduino board to connect to the internet, make and receive voice calls, and send and receive SMS messages. It uses the Quectel M10 radio modem and can be controlled via AT commands or the built-in Arduino GSM library.
The shield communicates with the Arduino via software serial on digital pins 2 (M10 TX) and 3 (M10 RX), with the modem's PWRKEY connected to pin 7. A SIM card from a network operator is required to connect to the cellular network. The board uses the 1.0 pinout compatible with the Arduino Uno Rev 3.
Key Features
- Quad-Band GSM/GPRS – Operates on GSM850MHz, GSM900MHz, DCS1800MHz, and PCS1900MHz frequencies
- Voice & SMS – Make and receive voice calls, send and receive SMS messages
- Internet Connectivity – Supports TCP/UDP and HTTP protocols via GPRS

- AT Command Support – Full AT command interface for direct modem control
- Arduino GSM Library – Comprehensive library with built-in methods for easy communication
Ideal For
- Remote monitoring and control of robots or household appliances
- Collecting sensor data (temperature, humidity) where Wi-Fi or XBee range is insufficient
- Building SMS-based alarm and notification systems
- IoT projects requiring cellular connectivity

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- RX
- RX means receive, usually showing data being received by the board. An RX indicator LED can help with troubleshooting USB or serial communication.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- TX
- TX means transmit, usually showing data being sent from the board. A TX indicator LED can help you see when the board is communicating or uploading code.
