# Unity3D mobile 4G internet web request is very slow

I have a windows VPS server and i have installed an Apache server on it. in my server I only have a simple text file that contains some few words.

My problem is that when I'm trying to sending a web request to my server by (4G sim card internet service ) for accessing to getting data from the text file , It works very slow .

Something about 30 or 50 secound ! but after first request if I try again there is no problem ! It works very fast !!! It seems This slowdown will only occur in the first connection .

But in other hand if I use WI-FI internet , there is no problem and every time I try to get data it works fast.

MY problem is only with sim card internet !

This is part of my code :

    IEnumerator Get_Data()
{
UnityWebRequest www = UnityWebRequest.Get(servers_Address + "file.txt?t=" + UnityEngine.Random.value);

yield return www.Send();
