I recently started using a service called Tailscale to provide a VPN connection back into my house. You can enable a setting called an Exit Node, and then when you make the VPN connection, you can choose to use the exit node. The exit node passes the traffic back into your house and then back out to the internet from the PC inside your home. To the world, it looks like you are browsing from your home PC. All of this enables encryption from your phone back to your home network, so if you connect to a sketchy WiFi, they can't snoop on your traffic. Walmart would have no idea what site you are browsing.
It sounds complicated, but it really wasn't. I enabled it all in like 15 minutes, and it was so easy I was like "That's it??" The service is free for X number of devices. I forget how many, but it was more devices than I own, and I'm nerdy.
