I would use a prepay and keep the battery out when not in use. Various cases have been prosecuted with tower location on certain numbers associated (time, location). So you have a throw away beside your personal phone;they could potentially associated both phones being together over the course of time and use that against you.
I think, from a very good source....that the government can turn on our phone and listen when not in use. They use it to fight the war on terrorism so I would think they could use it against us. Be careful out there, just don't assume you are safe because your phone is not registered to you. Obviously, it cost money for this type of surveillance and the local Po Po doesn't have that kind of access to funds or tech.
Ya know...here we go again..People that are ignorant to what law enforcement REALLY does should just sto spreading what they THINK is FACT
let me tell you..just like I said earlier..it aint costing LE not a damn thing to them to tap any phone..it's NEVER been expensive to tap a land line..It's even EASIER with cell phones..
You think govt. isn't allowed to buy unblocked wide-band frequency scanners?!! hmmm
you should know it's probably more like they give verizon or whoever 50 bucks and verizon throws them your last years worth of convo's on a dvd
the stuff IS NOT TOO EXPENSIVE and you dorks need to read up on tech before you go spouting oiff like you think you know..too expensive my ass
