could my mobile phone be monitered by a third party?

Answer 1

Not easily now but just a few years ago it was too easy. In fact when i used to hang out at Vanderbilt University we had a radio show where we'd tell people how to do it and use the conversations as samples between music..we did it for one night. There was a London DJ who actually took the concept and made music with cell phone samples.

If you're still using old school TDMA technology then yeah..with a police scanner. Otherwise it's hard but not impossible.

CDMA which is used by Sprint and Verizon is most secure. GSM which is used by the rest of the world is secure just not as secure. However all cell phone conversations go from your phone to the tower then a computer that verifies you pay your bill then across regular old telephone lines.

Those lines are in no way shape, form or fashion even REMOTELY secure. When i worked for cell phone companies we heard the rare complaint about hearing other conversations on the line and that was due to "phone bleed" when lines "bleed" electrical interference between each other.

So in order to listen to someone's cell phone conversation it's now best to just tap the lines.
