What Is The VPN For iPhone and why should you turn it on? It basically provides the encrypted tunneling of your data and hides the details of your activity surfing the Web. The VPN on the iPhone also conceals your actual IP address and helps you to remain unidentified and get around geoblocking, gaining access to international content. Be it commuting, working outside the office or on a public internet connection, the VPN at iPhone provides complete protection to make all your browsing activity untraceable and secured. Being the digital privacy cloak, it is essentially a must-have device to anyone who cares about communication security and online freedom in mobility.
