Or you have a VPN running and restart your phone and forget to turn it back on.

wireguard vpn client always resumes the connection
in my case also the DNS registration connects to me but that is withheld from the general public... the spooks and pigs can know it without any court procedure
if privacy is important you simply need to use a big userbase VPN or tor
i'd care more about privacy of my signals if there was any decently credible VPN system in the world but i am pretty sure most are too small, and i include tor in that
