The configuration files listed on your profile require a client called OpenVPN (This is specific free software to connect via a VPN).
For Android Devices use "OpenVPN For Android" found in the playstore.
For Mac use Stable https://tunnelblick.net/downloads.html
To get the VPN config file on to your device, youll have to use a web browser and login to your client area at: https://manage.unblockr.net/login
Sign in with your user name and password, then click on the VPN tab, you will then be able to download your unique config files here, or transfer them via USB/ADB.
Note: If your config files names end in .txt you will need to change it to .ovpn before you try to import them into OpenVPN
