Yes your original point was well made. It just wasn’t clear yet how DNS requests would leak search queries. So more precisely, multiple DNS requests with local cache misses in a short period of time can be used to infer search queries. Like if there are DNS requests for google, amazon, and a botany supplier one after another, then it could be inferred that you searched for something related to shopping and plants.

Thanks for the detailed response!

How would a DNS request leak a search query? Not much more than the domain name is sent in a DNS query. And likely the OS has the search engine in the DNS cache so each search doesn’t require a DNS query.

I had to essentially read the same thing four times before there was any new information in this post. Not sure if that’s a Jerboa thing or what, but probably could have been avoided.

I’ve also used VoIP.ms. Making and receiving calls is possible but requires setting up a SIP client app on your phone. Getting the settings right can be tricky.

Look into fixed wireless or 4G/5G home internet. Fixed wireless is sometimes exactly what you need in spots like that. It is not 4G or 5G, sometimes it is just long range WiFi or other lax spectrum.
