A simple way to prevent GPS tracking of cell phones

Alummum foil is also used on TV antennas to better direct the signal and make the signal stronger

 

Yeah, I remember those days when I was a kid.

 

I put my mobile phone in my microwave and I can still ring it. I thought that wasn't supposed to happen.

 

Using snack bags is clever! Aluminized mylar antistatic bags are good too. But silver-plated nylon cloth is best. It's far more durable. And it can easily be hidden under leather or ballistic nylon.

 

Old trick....been wrapping my old dump phone ages under few wraps of aluminium when I don't want to be bothered (much quicker than playing games with off/on)

Of course, for it to work, you have to make sure that it is
A) totally sealed
B) not touching your phone antenna! (my dump phone has internal antenna, not like these newer "smart" phones, so no problem there)

 

Incoming GPS signals are very weak (since they come from a satellite 20,000 miles away). The received signal from a cell tower is thousands of times stronger.
Keep in mind what this means for tracking purposes. Just because the GPS is blocked doesn't mean your position is fully blocked. The system still can record which cell tower you are closest to.

 

But did you turn it on? ....sorry couldn't resist that.
Seriously, I put my old brick in a near perfectly sized tin container, which I've lined with silver paper. Trouble is the lid is plastic though, but I still have that lined as well. Hopefully that works .

 

If you put your phone in there turned on just try ringing it from another phone or landline.

 

Isn't turning off 'Location' a better choice?

 

The turn off Location button is really the "let the user think their location is now private while we track them anyway" button.

 

Right. Sort of like "do not track" in the browser context.
