Is VPN included with IMac Iphone and Ipad
I read that to help keep my Iphone private and secure I should turn on a VPN in an insecure location. I read about what a VPN is, but still don't know whether it is already on my Iphone and if not how to access one. Is it an App I make my calls through somehow? The article suggested that Bitmask and Disconnect Secure Wireless can provide protection, but even after looking at their web sites I still can't figure out what I am supposed to do. Can anybody help? I would appreciate it. Thank you.
iPhone 4S, iOS 7.0.6
