All Cellular Carriers will comply with government subpoenas for your cell phone call, text, location, IP/DNS information.
It's almost impossible to escape this level of data intrusion since your IEMI is handset specific and registers with the Cellular Carrier.
What we get with GrapheneOS is to unplug ourselves from the world of subpoena free data harvesting and profiling.
Personally I use Verizon Prepaid with my name, credit card, etc... I "think" all major Cellular Carriers require a subpoena for the government to receive your cellular information, but could be mistaken.
I personally can't afford a crate of "burner" Pixel phones and "burner" sims to continually cycle through so I'm stuff at this level of privacy. Reality is that other than that unpaid parking ticket in Cornwall 12 years ago, I'm not likely to get sucked into a "drag net". If you're dealing drugs, then you can likely afford the crate of pixels to burn.
