Make sure that the two pins labeled as power key are shorted, it is required for the modem to turn ON.When the modem turns ON the power and the stat LEDs also turn ON and the network LED starts blinking.

Connect the Tx and Rx pins of arduino pins to Rx and Tx pins of GSM Modem.

If you are using DB9 connector for interfacing you need MAX232 circuitary for converting RS232 output of DB9 to TTL levels.

Run this code only after SIM800 Module has powered and connected to a Network.

We are sharing the Arduino code because the Arduino ecosystem is beginner friendly and easy to use.

And there is less likely to get any error even if you copy paste the code that we provide.

Would you please help me Actually I want to make a little project.
