GSM Shield with SMS and GSMclient problem

Projects Networking, Protocols, and Devices
1

I use the official GSM Shield with Mega2560 board.
I try to use in the same sketch SMS reception and connection to a webserver using GSM_client.
The SMS reception and connection to a webserver work well when they are not in the same sketch but not together.
I don't know if it's possible to use both in the same sketch?
Thank you for your help.

My code more simple :

#include <SD.h>
#include <Wire.h>
#include <GSM.h>

// PIN Number
#define PINNUMBER "1234"

// APN data
#define GPRS_APN "free" // replace your GPRS APN
#define GPRS_LOGIN "" // replace with your GPRS login
#define GPRS_PASSWORD "" // replace with your GPRS password

GSMClient client;
GPRS gprs;

GSM_SMS sms;

IPAddress server(???,???,???,???);

int i;
int port = ???;

Serial.println(F("connecting au reseau free..."));
// connection state
boolean notConnected = true;
previous = millis();

// After starting the modem with GSM.begin()
// attach the shield to the GPRS network with the APN, login and password

while(notConnected)

Is there anyone who have experienced with arduino GSM module?
