The telephone half of your home land line is as secure as a court warrant can make it. your computer modem, if it uses your land line, operates on the same phone wire but in a different frequency band so your high speed PC traffic goes thru a third party like a LAN, Google, etc. so that part can be seen by others. Your push button Princess is as secure as a home phone can be. Your home cordless signal is not powerful enough to get outside your house walls so it’s ok. But if you have a satellite phone you’re talking to the world. If you happen to live in a neighborhood that is fiber optic-connected your line conversations are also as safe as a search warrant but everything else involves a third party. It’s always that third party exposure that creates the weak link and the exposure. Remember that the phone company guys are not the problem-—they live in the same neighborhood and understand clearly the risk of double crossing a customer.
Thank you all for your great responses! Much appreciated.
