Issues with the Arduino GPRS module with RC522?

Hi,

I was trying the new GPRS module and it works but I am having an error when I want to post to Xampp.

Please find attached the code and the error from serial monitor.

#include <SoftwareSerial.h>
#include <String.h>
#include <SPI.h>
#include <MFRC522.h>

#define SS_PIN 10
#define RST_PIN 9

SoftwareSerial mySerial(7, 8);               //your pins to serial communication
MFRC522 mfrc522(SS_PIN, RST_PIN);  // Create MFRC522 instance.
String result;
int valor;

String token = "608c1cdaa6f94e98cd34541ef6c43aee";      //your token to post a value
//String result = "96307f50";      //ID of your variable

void setup()
{
  mySerial.begin(9600);                                                            //the GPRS baud rate
  Serial.begin(9600); 
  SPI.begin();      // Init SPI bus
  mfrc522.PCD_Init(); // Init MFRC522 card
  delay(500);//the serial communication baud rate
  Serial.println("Starting");
  delay(2000);
}

void loop()
{
  // Look for new cards
  if ( ! mfrc522.PICC_IsNewCardPresent()) {
    return;
  }

  // Select one of the cards
  if ( ! mfrc522.PICC_ReadCardSerial()) {
    return;
  }
  
  // Show some details of the PICC (that is: the tag/card)
  Serial.print(F("tag_id="));
  dump_byte_array(mfrc522.uid.uidByte, mfrc522.uid.size);
  Serial.println();  
}

// Helper routine to dump a byte array as hex values to Serial
void dump_byte_array(byte *buffer, byte bufferSize) {

  for (byte i = 0; i < bufferSize; i++) {
    result += String(buffer[i], HEX);
    Serial.print(String(buffer[i] < 0x10 ? " 0" : " "));
    Serial.print(String(buffer[i], HEX));
  }
  Serial.println(); 
  mfrc522.PICC_HaltA(); // Stop reading 
                                                 
  Serial.println("Sending to xampp Value="+ result);
  save_value(String(result));                                                      //call the save_value function
  
  if (mySerial.available())
    Serial.write(mySerial.read());
}
//this function is to send the sensor data to Ubidots, you can see the new value in Ubidots after running this function

void save_value(String result)
{
  int num;
  String le;
  String data;

  delay(1000);
  ShowSerialData();
}

void ShowSerialData()
{
  while(mySerial.available()!=0)
  Serial.write(mySerial.read());
}

and i’m getting the error,
