Can a Cell Phone be tracked when it's turned off ?

Yes. The only way to turn off a modern smartphone is to remove all power including the main battery and any reserve power source included in the design to preserve user settings, contacts, favorites, etc. This reserve might be a small coin-sized battery (uncommon) or a non-removable capacitor with enough charge to last for months.

Bottom line, if you don't want to be tracked, leave the phone at home.

Or tie it to a random dog.

then nothing will track it

there are cheaper alternatives, but I know this one works.

A Faraday bag can prevent cell phone tracking.

I bet if you ask Mossad, they would know

but until I personally know of someone who has tested one in an EMI chamber, then I'd never trust these.

I've used the Hammond die cast Al boxes in an EMI chamber so I know they are good to go.

100% yes. See this article supposedly they can track large crowds also

The Unplugged phone has an external switch (the kill switch) that kills all power.

You beat me to it. Now if only Apple would install that for me on the iPhone, I’d be quite happy.

I haven’t even used it yet, but it is there if I need it.

30-45 seconds on high in the microwave and it can't be tracked...

Now this is something I could get behind.

Thanks

So say the people who sell them.

The people who actually DO track phones would only say they work if they didn't.

See the problem here?

The Thyrm Darkvault blocking version got quietly pulled from the market early last year. They still offer the regular version, and then introduced a 2.0 blocking version, but I wonder.

I wouldn’t have thought a cell phone could be tracked when turned ‘off’, I do defer to the experts.

I think if one is worried about such, better to try deception, or leave the phone home, wherever.

With that Brian guy coming up to trial for the Idaho college student murders, he turned his phone off, and/or left it home during the murders. The one article mentioned that itself as suspicious, even though the cell signal didn’t put him at the murder site. He tried some deception technique.

For the most part, not something I get concerned about.

iPhones are fully capable of being used, on or off. “FindMy” the app on iPhones that allows you to track/find your phone has a lot of features. If the phone is turned off, you can turn it on. If the phone is on silent, you can make it play a sound. You can erase all content. This can all be done remotely, even if the phone is powered off. If the battery is dead, it shuts the phone off. When the battery is “dead”, there is still enough of a charge that you can power it on, find its location, erase all content, or play a sound. It’s not a lot a lot of reserve, but there is some there. It’ll even show the last location prior to going truly dead.

So yes, it’s completely traceable when powered off.

All the best spies buy burner phones and pull the batteries and the SIM card when not in use. But, now that eSIMs are coming into use, what's a spy to do??
