Voici le code (librairie dispo dans la biblio arduino, GSMSIM de Erdem A. Version 1.0.19)

#include <GSMSim.h>

#define RX 8
#define TX 7
#define RESET 2
#define BAUD 9600


GSMSim gsm;

/*
* Also you can this types:
* GSMSim gsm(RX, TX);
* GSMSim gsm(RX, TX, RESET);
* GSMSim gsm(RX, TX, RESET, LED_PIN, LED_FLAG);
*/

void setup() {
 // put your setup code here, to run once:
 Serial.begin(9600);

 Serial.println("GSMSim Library - SMS Example");
 Serial.println("");
 delay(1000);

 gsm.start(); // baud default 9600
 //gsm.start(BAUD);

 Serial.println("Changing to text mode.");
 gsm.smsTextMode(true); // TEXT or PDU mode. TEXT is readable :)

 char* number = "06256743**";
 char* message = "Hi my friend. How are you?"; // message lenght must be <= 160. Only english characters.

 Serial.println("Sending Message --->");
 Serial.println(gsm.smsSend(number, message)); // if success it returns true (1) else false (0)
 delay(2000);

 Serial.println("Listing unread message(s).");
 Serial.println(gsm.smsListUnread()); // if not unread messages have it returns "NO_SMS"

 Serial.println("Read SMS on index no = 1");
 Serial.println(gsm.smsRead(1)); // if no message in that index, it returns IXDEX_NO_ERROR
 
}

void loop() {
 // put your main code here, to run repeatedly:
