How to send massages on two numbers using GSM & Arduino board..
which code should i try for this..??

I am using this code for sending a massage from GSM Module & Arduino UNO. But i want to send same massages on multiple numbers..What changes should i made in my code..

const int buttonPin = 8;
const int buttonPin1 = 7;
const int buttonPin2 = 9;
const int buttonPin3 = 10;
bool i = false;
bool j = false;
bool k = false;
bool l = false;

void setup()
{
Serial.begin(9600);

pinMode(buttonPin, INPUT);
pinMode(buttonPin1, INPUT);
pinMode(buttonPin2, INPUT);
pinMode(buttonPin3, INPUT);

digitalWrite(buttonPin, LOW);
digitalWrite(buttonPin1, LOW);
digitalWrite(buttonPin2, LOW);
digitalWrite(buttonPin3, LOW);

delay(1000);
}
void loop()

{
sensor1();
sensor2();
}
void sensor1()
{
if (digitalRead(buttonPin1)== LOW && digitalRead(buttonPin) == HIGH && i == false)

{
Serial.println("OK");
delay(1000);
Serial.print("AT+CMGF=1\r\n");
delay(500);
Serial.print("AT+CMGS="");
Serial.print("+91...................");
Serial.print(""\r\n");
delay(2000);
Serial.print("Main Gate is Closed");
Serial.write(0x1A);
delay(1000);
i = true;
j = false;

}

if (digitalRead(buttonPin)== LOW && digitalRead(buttonPin1) == HIGH && j == false)
{
Serial.println("OK");
delay(1000);
Serial.print("AT+CMGF=1\r\n");
delay(500);
Serial.print("AT+CMGS="");
Serial.print("+91........................");
Serial.print(""\r\n");
delay(2000);
Serial.print("Main Gate is open");
Serial.write(0x1A);
delay(1000);
j = true;
i = false;
}
}
void sensor2()
{
if (digitalRead(buttonPin2) == HIGH && digitalRead(buttonPin3)==LOW && k == false)
{
Serial.println("OK");
delay(1000);
Serial.print("AT+CMGF=1\r\n");
delay(500);
Serial.print("AT+CMGS="");
Serial.print("+91....................");
Serial.print(""\r\n");
delay(2000);
Serial.print("Store room is Closed");
Serial.write(0x1A);
delay(1000);
k = true;
l = false;
}
if (digitalRead(buttonPin3) == HIGH &&digitalRead(buttonPin2)== LOW && l == false)
{
Serial.println("OK");
delay(1000);
Serial.print("AT+CMGF=1\r\n");
delay(500);
Serial.print("AT+CMGS="");
Serial.print("+91....................");
Serial.print(""\r\n");
delay(2000);
Serial.print("Store room is Open");
Serial.write(0x1A);
delay(1000);
l = true;
k = false;
}
