My question is simple! How to get maximum (Possible) privacy from ISP in case someone can’t or don’t want to use a vpn ?
Fir example, In some case tor browser is enough for many but they still need from a privacy from isp on other activities on mobile.
The only thing you gain from VPN is that the target server does not know your IP.
HTTPS is safe anyway and as such also the content of what you do.
The only other way you may leak information are DNS queries.
What to do about dns queries? In the privacyguides video i saw when we use a encrypted dns isp only see the ip address. So queries are hidden right ?
Switch DNS to a provider that supports DoH or DoT is about the only thing you can really do.
Without using a VPN or proxy, your ISP is going to be able to do DPI and know what connections you make. There really is no way around that.
