How I use vpn tricks for free internet in android ?

• Step 1:  Download Droid VPN ( important step :p) 

• Step 2: Airtel Sim card (These settings only works with airtel Which I'm going to share) 

• Step 3: Make account on https://droidvpn.com/index.php

• Step 4: Open Settings

                         Under Select Protocol setting select TCP

• Step 5: Under HTTP headers Use this 

                        Host: airtellive.com
                        X-Online-Host: airtellive.com

• Step 6: Save settings then restart Droid VPN. 

                        Now you can use free internet on airtel.
                        You can use these settings for another internet service provider. You need to have a free website or homepage or any IP. Then just put them into HTTP Headers section under settings.
