You may use a web service (eg https://www.whatismyip.com ) that shows your public IP address and your location. If the ip address and location match your OVPN service, then you are using vpn, if not, the vpn does not work or does not work correctly.

Try to ON/OFF VPN client on your A1300 and see the result from whatsmyip.com
With vpn enabled and disabled, public ip addresses must be different.
