Teleporting a GameObject in Unity 3D space is not difficult. Here’s some simple C# code that will help you do this.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Teleport : MonoBehaviour {

public GameObject ui;
public GameObject objToTP;
public Transform tpLoc;

void Start()
{
ui.SetActive (false);
}

void OnTriggerStay (Collider other)
{
ui.SetActive(true);
if (other.gameObject.tag == "Player")
{
objToTP.transform.position = tpLoc.transform.position;
}

}
void OnTriggerExit()
{
ui.SetActive (false);
}
}
