Does an ISP provided WireGuard tunnel hide my traffic from my ISP?

Hi guys,

I posted this over at r/VPN first but the mods removed it for some reason. Wasn’t sure where else to post it sorry?

As per the title just wondering if the WireGuard tunnel provided by my ISP (Neptune) hides traffic from them?

I also have a paid VPN app that I’d subscribed to previously, but signed up to a new ISP that has two free VPN tunnels included. So I’m also wondering what the pros/cons are of the ISP tunnel versus the app on my phone, I don’t really understand how the ISP tunnel works.

Thank you.
