SIM800L Module is a miniature cellular GSM / GPRS breakout board that allows GPRS transmission, sending and receiving messages, and making and receiving calls. This module supports quad-band GSM/GPRS network, which is available for GPRS and SMS data remote transmission. 

Having a small footprint, quad-band frequency support and low price make it perfect for any project that requires long-range connectivity. The device uses a serial communication method, so it communicates with almost every controller via the UART port. After giving voltage supply module boots up, search for the cellular network, and login automatically. 


  • Quad-band (850/900/1800/1900MHz) supports
  • Searches for network and login automatically
  • Can connect any global GSM network with 2G sim
  • Miniature size
  • AT command interface with auto baud detection
  • Lead-out buzzer and vibration motor control port
  • Scan and receive FM radio broadcast, send and receive SMS and call


  • Supply voltage: 3.8V to 4.2V (4V recommended)
  • Power consumption: 
    • Sleep mode: <2mA
    • Ideal mode: <7mA
    • GSM transmission (average): 350mA
    • GSM transmission (peak): 2000mA
  • Interface: UART (max 2.8V, serial interface)
  • Command support: 3G PP TS 27. 007, 27. 005 and SIMCOM enhanced AT commands
  • Sim Card slot: microSIM
  • Supported frequency: Quad-band (850/900/1800/1900MHz)
  • Temperature range: -40℃ to 85℃ 


  • This module is power-hungry and consumes 2A (peak)
  • The maximum recommended voltage in UART in this module is 2.8V. More than this will kill the module
  • If the power supply can not cater the required current well, the module will shut down.reset in the middle of the action

LED and indication

  • Fast blinking: no network coverage or searching
  • Slow blinking: logged in
  • Not blinking: check the power
