Happy to see a privacy-focused carrier, and it has better policies than any other carrier out there. But founder is formerly from Palantir and there’s a lot of VC money behind it (not inherently a problem, just flagging).
Thoughts?
The way anti-fingerprinting techniques work is by making you as much of a background digital character as possible. A privacy conscious user spoofing location and network traffic data on AT&T, Verizon, or T-Mobile is going to be far less likely to be singled out compared to customers on some bespoke cell network.
You should try to fake your traffic on a standard phone network (Using something like GrapheneOS with more granular control) to simply appear like another faceless data point rather than a "paranoid privacy user who bought this subscription for the privacy people", because that traffic will raise eyebrows much quicker.
