Heya,
VPN is a way to gain access to networks that are otherwise blocked in your geographic or networking location, or a way to not be someone else's product. That's the public commercial utilization at least.
As others mentioned above, get off the big public data networks, the "free" stuff isn't free, you sell "you" as the product to use it free and they use your data and habits to sell, sell, sell. So namely, get off any Google based service and social media.
There are tons of VPNs out there if you're just trying to get access to networks across the globe where there are blocks (like in Asia).
Very best,
