How to listen in on Phone calls with a Police scanner?

Question

Whats the code to prog in a police scanner to listen in on phone/cell phones? THANKS

Answer 1

Modern mobile phones and DECT cordless house phones are secured and digital, so you can't monitor them with a police scanner

This is unlike the old analog mobiles phones which caused Prince Charles some embarrassment in 1993.

There are still cheap, analog cordless house phones... these typically broadcast on 900 MHz.
