How much data value (MBytes) spend for an uploading with GSM client ?

I use the GSM shiled and with GSMClinet I upload data to a server. Can I find how mach data value (MBytes) uploading for each time that the uploading is done? Below is the part of script that is used for the uploading..

Thenx!

if (client.connect(server,port))
    {
      Serial.println("Client connects and upload data!");
      delay(100);
      
      client.print( "GET /water_quality_values/ARDUINOstorage.php?");
      client.print("node_id=");
      client.print(nodeID);
      client.print("&a=");
      client.print(temp);
      client.print("&b=");
      client.print(ConE);
      client.print("&c=");
      client.print(ConT);
      client.print("&d=");
      client.print(pH);
      client.print("&e=");
      client.print(ORP);
      
      client.println( " HTTP/1.1");
      client.println( "Host: your_server_web" );
      client.println( "Content-Type: application/x-www-form-urlencoded" );
      client.println( "Connection: close" );
      client.println();
      client.stop(); 
  
    }

You cannot see how much data have you spent. You can ask this question to your operator.
