How do I use WhatsApp using VPN on Windows Phone?

Since Windows Phone does not support many popular VPN protocols, especially OpenVPN, a good solution would be to create a VPN connection on your PC and share it through Wifi. Follow the given steps for Windows :

• Download the OpenVPN GUI software from here : https://openvpn.net/index.php/op...
• Go to http://www.vpnbook.com/freevpn  and download an appropriate certificate bundle
• Extract the required config file(s) to C:\Program Files\OpenVPN\config (assuming you installed OpenVPN in default directory)
• If you use a proxy server (suppose you use proxy 192.168.4.1 : 1080 with basic authentication) to connect to the internet, add the following line anywhere before the 'ca' markup tags (<ca></ca>) : 

http-proxy 192.168.4.1 1080 stdin basic

• Now start the VPN server by right clicking the notification icon and selecting the proper config. You should be asked for  OpenVPN credentials (which can be found from vpnbook.com ) and proxy credentials (if any) and
• Once successfully connected, reset all proxy settings (if any) to default no-proxy
• Now share TAP adapter through your wifi hotspot software (e.g. Connectify / netsh) and you are ready to browse WhatsApp on your Windows Phone (make sure proxy settings is set to no-proxy)

Notes:

• If you want to save your authentication settings instead of being prompted for it every time, create a file (e.g login.conf  in the config directory ) with username and password on separate lines. In the OpenVPN config file, modify this line:   

  auth-user-pass login.conf

• If you are using netsh to share your wifi (Windows), open Network and Sharing settings, select the VPN connection (one with 'access type : internet' ) -> properties -> sharing -> select 'Local Area Connection* 4'
• If you face problems connecting, check if the vpnbook password has changed (it changes frequently) , or try another ovpn-config file
