A VPN (a virtual private network) is a service that encrypts your internet connection and routes it through a server in another location. This makes it appear like you're accessing the internet from that server, masking your actual location and IP address. VPNs are useful for accessing region-locked content, like Netflix or BBC iPlayer, and maintaining privacy online. Many VPN providers offer free VPN apps for Android and iOS, so it's easy to get started. Download an app, log in with your credentials, and connect to a server. Some VPNs are faster than others, so it's worth shopping around to find the best one for your needs. Excellent free options include Windscribe and TunnelBear. Norton Secure VPN is perfect if you want a solid paid option.
