“VPN is useless on mobile, a firewall is better.”

What? A vpn tunnels your traffic to and from an external server so all your isp (or anyone else in the middle) sees is encrypted traffic to your vpn provider. A firewall blocks incoming connections to your device, either silently (black hole/ no response) or loudly (connection refused).

They are two different things, what exactly are you trying to do?

    I am indeed also confused.

    On mobile, firewalls are often created by creating a local virtual VPN that actually works as a firewall. As a result, you can only have one or the other enabled at a time.

    If you’re on your own trusted network, a firewall is probably the better choice. If you’re on an untrusted network, using a VPN to a trusted network is a better choice, and usually you can set up a firewall somewhere along the VPN chain as well.

    Why would you need a firewall on a trusted Network?
