How to use Serial more than 2? ESP32

Projects Libraries
1

Hello guys, I am using Gsm and fingerprint on my device. So I have been using Serial1 and Serial 2 and I need to add gps device therefore I need one more Serial. How can I use Gps device?
Project Subject: I want to do send gps data to the server from gsm every 5 seconds while the fingerprint is waiting. If finger comes I check on the server for match then continue to send gps data.

Thanks for answers..

 while (p != FPM_OK) {
    p = finger.getImage(); //finger check

    Serial.println(count);
    if (count == 500) { 
      gps.encode(SerialGPS.read());
      gpssocket.beginMessage(TYPE_TEXT);
      char sz[32];
      sprintf(sz, "%02d/%02d/%02d ", gps.date.month(), gps.date.day(), gps.date.year());
      char tz[32];
      sprintf(tz, "%02d:%02d:%02d ", gps.time.hour(), gps.time.minute(), gps.time.second());
    
      String date=String(sz)+String(tz);
      if (gps.location.isUpdated()) 
      {//Gsm Socket
        gpssocket.print("[{gps:true,loc_lati:" + String(gps.location.lat(), 6) + ",loc_long:" + String(gps.location.lng(), 6) + ",lastLocationDate:\""+date+"\"}]");
        Serial.println("[{gps:true,loc_lati:" + String(gps.location.lat(), 6) + ",loc_long:" + String(gps.location.lng(), 6) + ",lastLocationDate:\""+date+"\"}]");
      }

      int messageSize = gpssocket.parseMessage();
      if (messageSize > 0) {
        Serial.println("Received a message:");
        Serial.println(gpssocket.readString());
      }
      count = 0;
      gpssocket.endMessage();
    }
    count++;

  }

Answer:

You can use SoftwareSerial like Arduino ;

#include <SoftwareSerial.h>
TinyGPSPlus gps;
SoftwareSerial ss(19,21);
ss.begin(9600);
