Description
Chip: SIM800L
Voltage: 3.7-4.2V
Support networks: global quad-band network
Module size: 2.5cmx2.3cm
TTL serial port for serial port, you can link directly to the microcontroller. No need MAX232 Power module automatically boot, homing network Onboard signal lights all the way . It flashes slowly when there is a signal, it flashes quickly when there is no signal
Features:
- Quad-band 850/900/1800/1900MHz
- Connect onto any global GSM network with any 2G SIM
- Make and receive voice calls using a headset or an external speaker such as this and an electret microphone such as this.
- Send and receive SMS messages.
- Send and receive GPRS data (TCP/IP, HTTP, etc.).
- Find GSM (GPRS) location - this is not GPS.
- AT command interface with "auto baud" detection.

Note
My experience is that the SIM800L below 3.8V doesn't really work.
For further information visit: datasheet
So your job is to provide at least 3.8V to the module (ideally 4V), a power supply which outputs at least 2A.
There is a red status LED which tells you what operation the SIM800L is in.
64 MS ON - 800MS OFF - SIM800L is not registered to the network.
64 MS ON - 3000MS OFF - SIM800L is registered to the network.
64 MS ON - 300MS OFF - SIM800l is in GPRS mode
If the SIM800L keeps restarting after about 8-10 blinks, it may be due to lack of efficient power supply.
If you don't get OK after AT, check wiring! If you have a multimeter, check continuity of the wires.
Check the connections of the wires and solder joints! The module will only work when blinking.
