Resetting SIM 808 module using arduino program

I am using a sim 808 module interfaced with arduino uno for sending message when triggered by a pin on arduino but the problem that i am encountering is that i have to manually reset the sim808 module after sending few messages as the module enters the text mode and treats the final message sending command as a text also.So, i am searching a way to edit my code so that module can be automatically reset after sending each message.
I am using AT commands for this gsm communication.

Thanks in advance

#include <SoftwareSerial.h>

SoftwareSerial mySerial(10, 11); // RX, TX
int val = 0;

void setup() {
  // set the data rate for the ARDUINO and SoftwareSerial port
  Serial.begin(9600);
  mySerial.begin(9600);

pinMode(2, INPUT_PULLUP);
  // Open serial communications and wait for port to open:
  Serial.println("Starting the gsm communication");
  
  
  mySerial.println("AT");
  delay(1000);
  //while ()
  mySerial.println("AT+CSCS=\"GSM\"");
  delay(500);
  mySerial.println("AT+CMGF=1");
  delay(500);
  mySerial.println("AT+CMGS=\"mobile number\"");
  delay(500);
  mySerial.println("message");
  
  
}

void loop() { // run over and over
 if (mySerial.available()) { 
    Serial.write(mySerial.read());
  }
  val = digitalRead(2);
  //Serial.println(val);
  if (val==0) {
   
   mySerial.write(0x1A);
  }
  
  
 
}
