Unity location service not working

I am trying to make a location based app and i cant seem to get it to work. I used the example code here: https://docs.unity3d.com/ScriptReference/LocationService.Start.html but the code does not work, after a while i discovered that the problem was that location service was not enabled. How do i fix this? My code:

PS i am using android

 using UnityEngine;
 using System.Collections;

 public class Location : MonoBehaviour
 {
     IEnumerator Start()
     {
         // First, check if user has location service enabled
         if (!Input.location.isEnabledByUser)
             print("Location service is not enabled!");
             yield break;

         // Start service before querying location
         Input.location.Start();

         // Wait until service initializes
         int maxWait = 20;
         while (Input.location.status == LocationServiceStatus.Initializing && maxWait > 0)
         {
             yield return new WaitForSeconds(1);
             maxWait--;
         }

         // Service didn't initialize in 20 seconds
         if (maxWait < 1)
         {
             print("Timed out");
             yield break;
         }

         // Connection has failed
         if (Input.location.status == LocationServiceStatus.Failed)
         {
             print("Unable to determine device location");
             yield break;
         }
         else
         {
             // Access granted and location value could be retrieved
             print("Location: " + Input.location.lastData.latitude + " " + Input.location.lastData.longitude + " " + Input.location.lastData.altitude + " " + Input.location.lastData.horizontalAccuracy + " " + Input.location.lastData.timestamp);
         }

         // Stop service if there is no need to query location updates continuously
         Input.location.Stop();
     }
 }
