Hi All!
Thank you for reading and answering my post in advance.
My question is old voice flip phones could only be traced to the transmitting
tower. But I understand now that GPS is built in and is active whether you
activate it or not. So there is the potential to track you within three meters
Having worked for McCaw Cellular aka Cellular One aka AT&T Wireless
Services, I remember them doing this in the 90's. Even if your cell phone
doesn't have GPS capabilities, the phone companies could track you using
what's called triangulation. It's not as accurate as GPS, but it's close
enough.

I don't know about the t
Actually triangulation is used in GPS also. It is a very old tried and
true method.

Very true. Some difference are:
1. GPS is triangulation from satellites rather then cell towers
2. GPS was designed explicitly to provide location inform

Depends what you mean by "passive".

One might expect quite a bit that isn't true. Off is

If it's off enough to make an airline happy, it's not reporting anything,
even *if* it's passively tracking

The 3g / 4g transmitters and receivers operate through the same ping that
allows you to get a phone connection.
If you think soimeone might be tracking you to improve thier services and
sales of them then you'd be right.
If you have an android phone or a phone with google installed go to:

You're assuming that the GPS receiver in the device ha

Me neither.
This is also a knowable answer that any high-school level electronics
student can answer:
1. Monitor the current draw from the device's battery when the unit is
powered off. If you never see more an micro amps
