Cell-site simulators (CSS)—also known as IMSI Catchers and Stingrays—are a tool that law enforcement and governments use to track the location of phones, intercept or disrupt communications, spy on foreign governments, or even install malware. Cell-site simulators are also used by criminals to send...
Never going to be enough, use a VPN, and only use end to end encryption for calls…
Or use a VOIP service like google voice for the calls, at least force your monitors to get a warrant to google, make them do some leg work
None of these will fight a stingray
I’m confused. How would this not defeat a stingray? They would know your phone is there. But they wouldn’t see who you’re talking to, they wouldn’t hear your phone call, they wouldn’t see your encrypted messages. They wouldn’t see the traffic on your phone. What’s left?
Your IMEI, your carrier IP, your packet timing, any DNS your phone leaks, the IP of your VPN endpoint, your transmitter chipset, your likely OS kernel, any unreleased zero-days known to them (and maybe an exploit for them), and also a way to ack TCP packets it never intends to forward in order to sever your connection while letting your device keep taking for as long as possible, which might buy them a little extra time before you realize they’ve captured your session and cut you off.
Everything you said is true, but that is a reduced surface area versus the scenario where you’re sending your traffic naked over the wire. Including your voice traffic. Using a VPN while attached to a stingray is strictly a smaller risk surface.

Even that isn’t enough. The wireless modules of normal phones have direct access to system memory and, by law, have proprietary firmware. Some exploits have been found over the years. This needs to be isolated to avoid backdoors/bugs.
Not saying you’re wrong, but I’d love to read the sources to your claims.
By law? Which law?
