Problem of gy-neo6mv2 GPS module uploading on Arduino D1 WiFi esp8266

It didn't display any data on Arduino D1 WiFi esp8266, I also used the same pins RX 4 and TX 3, 3.3V, GND on Arduino UNO and it worked. Why not on Arduino D1 WiFi esp8266.

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

SoftwareSerial mySerial(3,4); // tx rx
//#define GPS_UART_RX_PIN 4
//#define GPS_UART_TX_PIN 3

TinyGPSPlus gps; // create gps object

void setup(){
Serial.begin(9600); // connect serial
Serial.println("The GPS Received Signal:");
mySerial.begin(9600); // connect gps sensor

}
 
void loop(){
    while(mySerial.available()){ // check for gps data
    if(gps.encode(mySerial.read()))// encode gps data
    { 
    
    //Latitude
    Serial.print("Latitude: ");
    Serial.println(gps.location.lat(),6);
    
    //Longitude
    Serial.print("Longitude: ");
    Serial.println(gps.location.lng(),6); 

    //Altitude
    Serial.print("Altitude: "); 
    Serial.println(gps.altitude.feet());

    //Speed
    Serial.print("Speed: "); 
    Serial.println(gps.speed.mph());

    // Number of satellites connected
    Serial.print("Number of Sats connected: "); 
    Serial.println(gps.satellites.value());

    delay(2000);
    
   }
  }
  
}
