VPN's are a great thing. As you probably know, with "free WiFi" you're information is actually available to hackers because the network is not secure. Thats why a VPN is a great thing. Connect to WiFi then connect to a VPN and you're all set and ready to go. I actually subscribe to VPN Unlimited myself and it works amazingly, although I mostly only use it when I'm traveling to China. And yes it is one of the few VPN's that do work well against their firewall.
You can pick up your lifetime subscription to VPN Unlimited from the Android Headlines Deals Store today.
