GSM interfacing with Blynk

Need Help With My Project
1

I am working on project for which i need to track the location of my vehicle here is the code below. I am using NEO 6M GPS module and SIM 800 A module.
Issues
1.) Connection to GPRS failed.
2.)sometimes i also get the error Cannot init.
3.) wasn’t online yet on android phone

#define BLYNK_PRINT Serial
#define TINY_GSM_MODEM_SIM800

#include<TinyGsmClient.h>
#include<BlynkSimpleSIM800.h>

#include <SoftwareSerial.h>
#include<TinyGPS++.h>

SoftwareSerial gsm(8,9);
TinyGPSPlus gps ;

char apn[]=" ";//
char auth[]=" ";//project authentication key
char user[]="";//blank
char pass[]="";//blank

WidgetMap myMap(V0);

TinyGsm modem(gsm);

unsigned int move_index=1;
void setup()
{
  Serial.begin(9600);
  gsm.begin(115200);
  Blynk.begin(auth,modem,apn,user,pass);
}

void loop()
{
    Blynk.run();  
    while(Serial.available())
    {
        gps.encode(Serial.read());
        if (gps.location.isUpdated())
        {  
          delay(1000);
          gsm.println("AT+CMGF=1");
          delay(1000);
          gsm.println("AT+CMGS=\"**********\"\r");
          delay(1000);
          gsm.println("lattitude=");
          gsm.println((gps.location.lat()),6);
          gsm.println("longitude=");
          gsm.println((gps.location.lng()),6);
          gsm.println("Speed=");
          gsm.println(gps.speed.mps(),1);
          delay(1000);
          gsm.println((char)26);
          delay(1000);
          Blynk.virtualWrite(V1,String((gps.location.lat()),6));
          delay(10);
          Blynk.virtualWrite(V2,String((gps.location.lng()),6));
          delay(10);
          myMap.location(move_index,gps.location.lat(),gps.location.lng(),"value");
          delay(60000);
         }
      }
  }

You need to move the code out of void loop for starters:
