delay(5000);
SendMessage();
}

void loop()
{

if (mySerial.available()>0)
textMessage = mySerial.readString();
Serial.print(textMessage);
delay(10);
}

void SendMessage()
{
mySerial.println("AT+CMGF=1"); //Sets the GSM Module in Text Mode
delay(1000); // Delay of 1000 milli seconds or 1 second
mySerial.println("AT+CMGS="+639290584072"\r"); // Replace x with mobile number
delay(1000);
mySerial.println("The system is ready");// The SMS text you want to send
delay(100);
mySerial.println((char)26);// ASCII code of CTRL+Z
delay(1000);
