Sending data to TELNET app with ESP8266 and arduino uno

I started to test the ESP8266 module, i wrote in the serial port this commands: AT, AT+RST, AT+CWMODE=1(station mode), AT+CWLAP, AT+CWJAP=“My network name”,“password”, AT+CIPMUX=1, AT+CIPSERVER=1,80, AT+CIPSEND=0,“numer of char of my string”, “MyMessage”, AT+CIPCLOSE=0 and it work, its sends the message to my phone.
Now I try to do some function that sends automatically those commands, but when i get to the sending message part it gives me an error.
I post my code below:

#include <SoftwareSerial.h>
SoftwareSerial ESPserial(9, 10); // RX | TX

void setup()

{

Serial.begin(9600); // communication with the host computer

// Start the software serial for communication with the ESP8266
ESPserial.begin(9600);
delay(1000);
Serial.println("");
Serial.println(“Remember to to set Both NL & CR in the serial monitor.”);
Serial.println(“Ready”);
Serial.println("");
trimiteDate(“AT+IPR=9600”,1000);
trimiteDate(“AT”,1000);
trimiteDate(“AT+RST”,1000);
trimiteDate(“AT+CWMODE=1”,1000);
trimiteDate(“AT+CWLAP”,1000);
trimiteDate(“AT+CWJAP=“DIGI_d61430”,“ddcc29eb””,1000);
trimiteDate(“AT+CIFSR”,1000);

trimiteDate(“AT+CIPMUX=1”,1000);
trimiteDate(“AT+CIPSERVER=1,80”,1000);
scrie(“Sir de caractere”,1000);

}

void loop()

{
// listen for communication from the ESP8266 and then write it to the serial monitor
if ( ESPserial.available() ) { Serial.write( ESPserial.read() ); }
// listen for user input and send it to the ESP8266
if ( Serial.available() ) { ESPserial.write( Serial.read() ); }
}

void trimiteDate(String comanda, const int timp ){
ESPserial.println(comanda);

while ( ESPserial.available() ) { Serial.write( ESPserial.read() ); }
while ( Serial.available() ) { ESPserial.write( Serial.read() );}
delay(timp);
}

void scrie(String sir, const int timp){
int lungimeSir = sir.length();
String startTransmisie = “AT+CIPSEND=1,”;
String stopTransmisie = “AT+CIPCLOSE=0”;
String sirDate = startTransmisie + lungimeSir;
trimiteDate(sirDate,1000);

  ESPserial.println(sir);

  trimiteDate(stopTransmisie,1000);
  delay(timp);

}
