Connect Arduino GSM/GPRS Shield to a Mobile Cell Network
I bought a SIM900 board, but I can not connect there with the Arduino. To send AT commands on the serial the SIM900 doesn't respond, but the LED indicating that the network is on. I've tried to change the baud rate of 9600 to 19200 in the firmware of the Arduino, but it still fails.

The Arduino GSM Shield 2 allows an Arduino board to connect to the internet, make/receive voice calls and send/receive SMS messages. The most recent revision of the board uses the 1. 0 pinout on rev 3 of the Arduino Uno board. Requires an Arduino board (not included) Operating voltage 5V (supplied from the Arduino Board)
m - How to communicate the Arduino board with SIM900
In this project, we will employ GSM module SIM900 display messages sent to the module on LCD using Arduino UNO. . About GSM Module(SIM900): SimCom SIM900 GSM / GPRS Modem can accept any GSM network operator SIM card and act like a mobile with its own unique phone number. The advantage of using this modem will be that you can use its RS232 port to communicate.
Let'S Play With Arduino: GSM Modem with Arduino UNO
I am using Arduino Uno and trying to connect to a SIM900A GSM module using serial communication. I am not receiving anything from the module at all. No communication with SIM900A using Arduino Uno. Ask Question 0 $\begingroup$ Information about SIM900 can be found here.

Insert a SIM card in the module, connect the antenna and place it over the Arduino Uno. Power up the Arduino Uno connecting it to the PC. You can see a red LED in the Module lights up. Now press the “SIM900 Power” button right under the LED.

Send sms with arduino and sim900 gsm module
t's doing like that when ARDUINO can't communicate with SIM900 over serial. Check the baudrate of the module(by using a serial to USB converter try at 9600 with command check with baud 115200 which is usually default).
Send and Receive Text Messages (SMS) with GSM SIM900
How to interface GSM/GPRS Shield (SIM900A/SIM900/SIM800) To an Arduino Manoj January 9, (USB – to communicate with the PC directly without an ATmega328 on your Uno, Arduino – to communicate with the ATmega328 on your Uno) I want to to connect sim 800 shield and uno board without stacking it on uno board. The connections are
