How to send sms

futurehelperforcodes:
what blue wire are you talking about ?

That was humor because you ask a question totally without giving us context to answer.

Please fix your previous post and add the [ code ] tag around the code so that it's easier to read.also press CTRL-T in the IDE before copying the code so that is indented properly.

To your pb:

Why are you kinda trying to declare the SendTextMessage in the middle of the loop? And probably added a semicolumn at the end because the compiler was complaining?? Does this make sense to you?

void SendTextMessage();
    {
    mySerial.println("AT+CMGF=1");                //to print number in text mode
    delay(1000);                                     //in miliseconds
    mySerial.println("AT+CMGS=\"+919717889680\"\r");  //for the number to which the message has to be sent
    delay(1000);                                       //in miliseconds
    mySerial.println("The current location is:");       //the message to be sent
    delay(1000);                                         //the delay in miliseconds
    }

Besides Your problem is that you are using a myserial variable that has never been declared. You did not copy very well the example most likely...
