Also, i am using this code:

#include <SoftwareSerial.h> //Libreria para permitir comunicacion serial en otros pines

SoftwareSerial cell(2,3); // Puerto serie para comunicacion con el modulo GSM

unsigned char CR=13; // caracter de retorno de linea

void setup()

{

cell.begin(9600); // Iniciamos el cellular shield

delay(35000); // Delay de 35 segundos para inicializacion del modulo GSM

cell.println(“AT+CMGF=1”);// Preparamos el modulo GSM para envio de SMS

}

void loop()

{

// Numero de telefono entre comillas AT+CMGS=“Numero”

delay(1500);

cell.write(“AT+CMGS="4271157958"”);//comando at para introducir el num

cell.write(CR);

delay(1500);

cell.write(“Prueba1 exitosa”);//texto del SMS

cell.write(CR);

delay(500);

cell.write(0x1A); // ASCII equivalente al Ctrl-Z, final de SMS

delay(15000); // Tiempo de “descanso” del modulo

while(true)

delay(1); // Bucle infinito para no enviar infinitos SMS.

}

Could you help me to solve this problem, please?](Photo Storage)](Photo Storage)](Photo Storage)](Photo Storage)](Photo Storage)](Photo Storage)

What problem? You haven’t stated it yet.

Forget about sending a sms for the moment. Just send AT to it (with carriage return and linefeed folowing), and you should get OK back. If that works then you have a connection with it and can proceed to more complicated commands.

I can’t understand the comments in the code because of the language. Italian? So I don’t know what it is trying to do.
