Free VPN, Yes It’s For WiFi Hotspot & Mobile!
A virtual private network (VPN) extends a private network across a public network, enables individual internet users to send and receive data across public networks as if their devices were directly connected to the private network.
So that users may secure their transactions with a VPN, to circumvent geo-restrictions, or to connect to servers for the purpose of protecting personal identity.
Apps running across the VPN may therefore benefit from the functionality and management of the private network.
