I wonder if the cell phone needs to be turned on to be tracked?

No it doesnt. The only way to avoid the cell phone tracking, is to remove the battery from the phone. Every Cell phone transmits its identification number and cell location every 20 minutes whether the phone is on or not.

So, take the batteries out when you want privacy in your wherabouts. A, leave them in and send the phone somewhere with a friend when you need an alibi?
