SIM800L GSM GPRS Module

The SIM800L GSM GPRS Module is a compact quad-band cellular communication module that enables SMS messaging, voice
calls, and GPRS data connectivity in embedded projects. Based on the SIMCom SIM800L chip, this module supports 2G GSM networks
and communicates with microcontrollers via a standard AT command UART interface.
Widely used in IoT devices, remote monitoring systems, and GPS trackers, the SIM800L is a proven and affordable solution for adding
cellular connectivity to Arduino, ESP32, and Raspberry Pi projects.

Key Applications🔹
SMS alert and notification systems
IoT remote monitoring and control
GPS tracker cellular data upload
Arduino and ESP32 GSM communication
Remote door and access control systems

Why Choose This Module?🔹
Quad-band GSM/GPRS support (850/900/1800/1900 MHz)
SMS, voice call, and GPRS data capability
AT command UART interface
Low standby current consumption
SIM card holder included
Compact form factor

Technical Specifications🔹
Chip: SIMCom SIM800L
Network: Quad-band GSM/GPRS 2G
Interface: UART (AT commands)
Supply Voltage: 3.4 V – 4.4 V DC
Current: Up to 2 A peak (during transmission)
SIM Type: Micro SIM

What's Included🔹
1 × SIM800L GSM GPRS Module

Pro Tip🔹
Use a dedicated LiPo battery or a high-current DC-DC converter to power the SIM800L — standard Arduino 3.3 V regulators cannot💡
supply the 2 A peak current required during GSM transmission.

Note:⚠️
The SIM800L requires a 2G GSM network. In regions where 2G has been decommissioned, this module will not connect to any network.
Check local network availability before purchasing.
