GSM Module V3.0

Projects Programming
1

Hello, I am using GSM_Module_V3.0 to send an SMS.
I connected the shield with Arduino Uno. I Tried so many codes. But none seems to work.
I also plugged the Arduino with a power supply. I used the GSM library and its examples. It didn't work.
Does anyone know how to make it work ????

I used this code,,,,

code

byte gsmDriverPin[3] = {
  3,4,5};//The default digital driver pins for the GSM and GPS mode
//If you want to change the digital driver pins
//or you have a conflict with D3~D5 on Arduino board,
//you can remove the J10~J12 jumpers to reconnect other driver pins for the module!
void setup()
{    
  //Init the driver pins for GSM function
  for(int i = 0 ; i < 3; i++){
    pinMode(gsmDriverPin[i],OUTPUT);
  }
  digitalWrite(5,HIGH);//Output GSM Timing 
  delay(1500);
  digitalWrite(5,LOW);  
  digitalWrite(3,LOW);//Enable the GSM mode
  digitalWrite(4,HIGH);//Disable the GPS mode
  delay(2000);
  Serial.begin(9600); //set the baud rate
  delay(5000);//call ready
  delay(5000);
  delay(5000);
}
 
void loop()
{  
  Serial.println("AT"); //Send AT command  
  delay(2000);
  Serial.println("AT");   
  delay(2000);
  //Send message
  Serial.println("AT+CMGF=1");
  delay(1000);
  Serial.println("AT+CMGS=\"15800449871\"");//Change the receiver phone number
  delay(1000);
  Serial.print("HELLO");//the message you want to send
  delay(1000);
  Serial.write(26);
  while(1);
}

Hello,,
Nothing has worked.

check out this link:

I have read it but nothing has worked.
How can I know that the SIM card I am using doesn't support this device.
