my code is //Code for Dialling a number

char phone_no[]=”9895040519”;

void setup()

{

Serial.begin(9600); //Open Serial Connection at baudrate 9600

delay(2000);

Serial.println(“AT”); // Wake up GSM

Serial.print(“ATD”); //Dial the phone number using ATD command

Serial.print(phone_no);

Serial.println(“;”); // Semicolon is a must at the end

delay(10000);

Serial.println(“ATH”); // After a delay of 5 secs Hang the call

}

void loop()

{

// empty loop.If you enter the above code here,the call will be made FOR EVER repeatedly.

//Take Caution while coding under loop.At some condition you’ve to terminate the Call

}

You probably 'cut and pasted' from a web page so you have 'extended' characters.

Save in notepad (or similar) first, then copy it into the IDE.

now error has cleared but there is no voice call is generated.
I want to call to the number 9895040XXX from 8589001XXX( which is inserted in the gsm module

Try country code, followed by area / operator code, followed by subscriber code.
