Ever more convinced it's been a good idea to route all my phone traffic through WireGuard.

Though it interests me why mobile networks feel they are able to do this whereas landline ISPs don't tend to in such great numbers. At least, as far as I am aware, Deutsche Telekom aren't adding headers to bare HTTP requests etc.

I'm wondering if it's actually worth caving and having my home traffic tunneled to some provider more reputable.
