1. Install OpenVPN (Arne Schabe version) in Google Play (or F-droid if you don’t have Google Applications).
  2. Download the server file you need in the controlpanel and save it somewhere on your Android device.
  3. Open the OpenVPN for Android application and import the .ovpn file (this will create a new profile, name it like you want)
  4. (Optionally) Edit the imported profile and set your username and password if you do not want to be asked every time.
  5. You can now connect to that profile. On connection it will show the log while trying to connect.
