What is a VPN?
A VPN creates a secure, encrypted “tunnel” over the internet between your computer, smartphone or tablet and whatever website or app you are trying to access. This is made possible by redirecting your connection via a VPN server in another country, which makes it appear to a website or application that you are just another local visitor.ff92a33d83
