TinyGPS++ for NEO6m GPS and SIM800L using Arduino Nano

Hello, I need help in building a device that in one press of a button, it will give a gps coordinates through SIM800L software serial. I am currently use software serial for SIM800L and hardware serial on pins 0 and 1 Tx and Rx for the NEO6m GPS module. I can get the coordinates of latitude and longitude, however, everytime I try to send the coordinates through the sim, sometimes the values goes back to NMEA sentences, sometimes not. Here is my code:

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

HardwareSerial& gpsSerial = Serial;

int SIM_Tx_Pin = A1;
int SIM_Rx_Pin = A0;

int Emergency_Button = 12;
int Button_Power = 10;
int Reset_Val_Pin = 11;

float latitude;
float longitude;

int Prev_Val = 0;
String Locked_Location;

String SMS = "";

SoftwareSerial SIM_Serial(SIM_Tx_Pin, SIM_Rx_Pin);
TinyGPSPlus gps;

void setup() {

  Serial.begin(9600);

  gpsSerial.begin(9600);
  SIM_Serial.begin(9600);

  pinMode(Button_Power, OUTPUT);
  pinMode(Emergency_Button, INPUT_PULLUP);
  pinMode(Reset_Val_Pin, INPUT_PULLUP);
}

void loop() {
  digitalWrite(Button_Power, LOW);
  int Button_Value = digitalRead(Emergency_Button);
  int Reset_Val = digitalRead(Reset_Val_Pin);

  if (Button_Value == 0 && Prev_Val == 0) {
    Send_SMS_1();
    //Prev_Val = 1;
  }
  if (Reset_Val == 0) {
    Prev_Val = 0;
  }

  GPS_Run();
}

void displayInfo() {
  if (gps.location.isValid()) {

    latitude = gps.location.lat();
    longitude = gps.location.lng();

    Serial.print("Latitude: ");
    Serial.print(gps.location.lat(), 6);
    Serial.print(", Longitude: ");
    Serial.println(gps.location.lng(), 6);

    SMS = "Latitude: " + String(latitude, 6) + ", Longitude: " + String(longitude, 6);

  } else {
    Serial.println("Location: Not Available");
  }
  delay(1000);
}

void GPS_Run() {
  while (gpsSerial.available() > 0) {
    char c = gpsSerial.read();
    if (gps.encode(c)) {
      if (gps.location.isValid()) {
        displayInfo();  // Display the GPS information if valid
      }
    }
  }

  if (millis() > 5000 && gps.charsProcessed() < 10) {
    Serial.println("No GPS detected");
  }
  delay(10);
}

void Send_SMS_1() {
  SIM_Serial.println("AT");  //Once the handshake test is successful, it will back to OK
  updateSerial();
  SIM_Serial.println("AT+CMGF=1");  // Configuring TEXT mode
  updateSerial();
  SIM_Serial.println("AT+CMGS=\"+63**********\"");  //change ZZ with country code and xxxxxxxxxxx with phone number to sms
  updateSerial();

  //SIM_Serial.println("Emergency response needed at coordinates: [latitude/longitude]" + String(latitude, 6) + " " + String(longitude, 6) + ", Assistance required immediately.");
  if (SMS.length() < 38) {
    SIM_Serial.println(SMS);  // Send the constructed SMS message
    updateSerial();
    SIM_Serial.write(26);  // Ctrl+Z to terminate the SMS
  } else {
    Serial.println("SMS is too long, not sent.");  // Inform if SMS is too long
  }
}


void updateSerial() {
  delay(100);
  while (Serial.available()) {
    SIM_Serial.write(Serial.read());  //Forward what Serial received to Software Serial Port
  }
  while (SIM_Serial.available()) {
    Serial.write(SIM_Serial.read());  //Forward what Software Serial received to Serial Port
  }
}
