Best mobile VPN 2021: Ensure your privacy anywhere

Virtual Private Networks (VPNs) are great for protecting your internet privacy, but they're not perfect. Some VPNs don't take good care of your "private" information. Mobile VPNs face all these issues and more.
VPNs use encryption technologies, such as IP security (IPSec), Layer 2 Tunneling Protocol (L2TP)/ IPSec, Secure Sockets Layer (SSL), and Transport Layer Security (TLS), and WireGuard to create a virtual encrypted "tunnel" between your computer and a VPN server. While your traffic is in this tunnel, no one can see where you're going or what you're doing. You're invisible.
Well, your traffic should be invisible. But you can't trust all VPN providers. Some fake VPNs snoop on your traffic, while others don't always encrypt your traffic. Still, others log your activities or use your own domain name servers (DNS). When a VPN uses your DNS, then your ISP can still see where you're going. That defeats the entire purpose of a VPN. In particular, if you find a "free" VPN, run -- don't walk -- away from it. They're almost always scams.
