I have found that tinfoil has many uses like duct tape in solving everyday problems like yours. Just wrap your cellphone in several layers of tinfoil and they won't be able to track you, really! Trust me. ;-)
“even with the phone turned off”
If that is the case, I’m guessing that the battery would die out if it stayed off for very long so I seriously doubt it. Many hikers only turn their phone on periodically to save the battery.
When my cellphone is off but the battery is in and it’s near a radio that’s on or near my laptop and the sound is on I hear four or five beeps every so often.
That is correct.
Years ago a friend of mine had problems with his phone. While talking to tech support they asked him to turn the phone off to apply an update.
He said, “Do you need me to turn it back on?”
“Nope.”
Unless you pull the battery you can be logged. All part of the E911 law to make us safer, ya’know.
It depends upon how you define ‘Off’.
If you are completely ‘Off’; your phone has to re-register and find towers, effectively re-boot and re-initialize. Typically, when a phone is turned ‘off’ it’s really set to a sleep mode. So, when you drive, the phone isn’t really burning a whole lot of power; but it is picking up new cell towers and dropping other cell towers as they move out of range.
If you want total radio silence; you have to remove the battery - or turn the phone completely OFF - such that it has to reboot when you re-power it on again.

And once the biometric patch tattoo thingie is worked out, you won't even be able to take the battery out.
It’s my understanding that the phone cannot be tracked if the battery is removed. But......they could place a very small battery in the phone, on the circuit board that couldn’t be removed. Believe me, if they want to track you via this device or any other, like GPS or computers in your car, they can.
Maybe you can check with some fancy RF equipment, or even a radio which the cell phone interferes with when checking in. I know some GSM phones can make speakers buzz when they are very close and are checking into the tower.
In the movie Spartan, Val Kilmer’s character actually did specifically take out the battery from the cellphone...twice in the movie. The movie/script was based on the founder of Delta Force so there might be truth to it.
If you don’t want your phone to be used as a tracking AND listening device, remove the battery.
The specific line in the book is:
“Users broadcast their location whenever their phone is turned on - and the phones can be manipulated to do such broadcasting even when the phone is off.”
A key word is “manipulated” which I would take could mean a possible default setting in the phone, a command signal from the service provider, etc.
The author has a strong engineering, cybersecurity and public policy background so I don’t dismiss the comment although there was no footnote associated with the statement.
I always keep a few of those cellophane-foil potato chip bags with me and toss my phone in there when I’m not using it.
You could drop that sucker in a mini-potato chip bag (those thing METAL types) and be fine, I think.
Here’s an experiment that will convince you of the value of a Farraday Cage:
Put phone A in a microwave, door open. Call the phone, observe ring.
Close the door of the OFF microwave:
Call the phone. It does not ring.
Those are the effects of a (small) Farraday Cage.
Use throwaways from WalMart and your concerns about being tracked are over.
Just make sure you really do throw them away every so often.
If you keep it in a bucket of water you will not be tracked.
Don’t know how much of this should be public info. My friend works for the Secret Service, and according to him the phone must be on before it can be tracked.

I'm an electronics engineer, and I have a spectrum analyzer (measures transmit power, even short pulses). By making a call, I established the frequency range and power that it operated on. I also established a controlled radio environment where no signals except the cell phone's would register on the analyzer. Then, I turned off the cell phone and continued monitoring it.
No transmission for a half hour now.
As soon as I turned it back on, it started transmitting again.
They can't track ya if ya don't transmit.
Or if they can't hear ya -- y'all with the Faraday Cage ideas are on the right track. Just wrap it in good ol' aluminum foil.
an article came out in 2006 that the FBI could use cell phones even phones that were turned off as a wiretap

you can track any cell phone at http://www.gpsspying.com/
Let them track you...it keeps them busy not tracking the rest of us.
