Define Pin RX, TX Without SoftwareSerial Arduino - arduino

Question

Hi I did 2 diferent codes, then after verifying that they work i try to combine them and I got a problem. I used GSM.h to controle my GSM module, and to controle the GPS I used the SoftwareSerial.h.
I tryed to combine these to codes and this 2 libraries conflit with each other.
Can some one help me?
This is my code
//GSM
#include <GSM.h>
#define PINNUMBER "3805"
GSM gsmAccess; // include a 'true' parameter for debug enabled
GSM_SMS sms;
//N de telefone de envio
char remoteNumber[20]= "914181875";
//Conteudo do SMS
char txtMsg[200]="Tester";
int val = 0;
//GPS
//#include <SoftwareSerial.h>
#include <TinyGPS.h>
TinyGPS gps;
SoftwareSerial ss(4, 3);
static void print_float(float val, float invalid, int len, int prec);
int button = 7;
void setup()
{
// initialize serial communications
pinMode(button, INPUT);
Serial.begin(9600);
Serial.println("SMS Messages Sender");
// connection state
boolean notConnected = true;
// Start GSM shield
// If your SIM has PIN, pass it as a parameter of begin() in quotes
while(notConnected)
{
if(gsmAccess.begin(PINNUMBER)==GSM_READY)
notConnected = false;
else
{
Serial.println("Not connected");
delay(1000);
}
}
Serial.println("GSM initialized");
}
void loop()
{
val = digitalRead(button);
if (val == HIGH){
sendSMS();
}
}
void sendSMS(){
Serial.print("Message to mobile number: ");
Serial.println(remoteNumber);
// sms text
Serial.println("SENDING");
Serial.println();
Serial.println("Message:");
Serial.println(txtMsg);
// send the message
sms.beginSMS(remoteNumber);
sms.print(txtMsg);
sms.endSMS();
Serial.println("\nCOMPLETE!\n");
}

I would try using the AltSoftSerial library instead of SoftwareSerial:
https://github.com/PaulStoffregen/AltSoftSerial
The disadvantage of this library is it requires you to use specific pins for serial communication with your GPS hardware, which are different from the pins you're currently using:
// AltSoftSerial always uses these pins:
//
// Board Transmit Receive PWM Unusable
// ----- -------- ------- ------------
// Teensy 3.0 & 3.1 21 20 22
// Teensy 2.0 9 10 (none)
// Teensy++ 2.0 25 4 26, 27
// Arduino Uno 9 8 10
// Arduino Leonardo 5 13 (none)
// Arduino Mega 46 48 44, 45
// Wiring-S 5 6 4
// Sanguino 13 14 12
I don't have the hardware to test but the following code does compile:
//GSM
#include <GSM.h>
#define PINNUMBER "3805"
GSM gsmAccess; // include a 'true' parameter for debug enabled
GSM_SMS sms;
//N de telefone de envio
char remoteNumber[20]= "914181875";
//Conteudo do SMS
char txtMsg[200]="Tester";
int val = 0;
//GPS
#include <AltSoftSerial.h>
AltSoftSerial ss;
#include <TinyGPS.h>
TinyGPS gps;
static void print_float(float val, float invalid, int len, int prec);
int button = 7;
void setup()
{
// initialize serial communications
pinMode(button, INPUT);
Serial.begin(9600);
Serial.println("SMS Messages Sender");
// connection state
boolean notConnected = true;
// Start GSM shield
// If your SIM has PIN, pass it as a parameter of begin() in quotes
while(notConnected)
{
if(gsmAccess.begin(PINNUMBER)==GSM_READY)
notConnected = false;
else
{
Serial.println("Not connected");
delay(1000);
}
}
Serial.println("GSM initialized");
}
void loop()
{
val = digitalRead(button);
if (val == HIGH){
sendSMS();
}
}
void sendSMS(){
Serial.print("Message to mobile number: ");
Serial.println(remoteNumber);
// sms text
Serial.println("SENDING");
Serial.println();
Serial.println("Message:");
Serial.println(txtMsg);
// send the message
sms.beginSMS(remoteNumber);
sms.print(txtMsg);
sms.endSMS();
Serial.println("\nCOMPLETE!\n");
}
