I believe that any smart card is ultimately cloneable, if you have the original.
Credit cards use them now, and I guess you are at the same risk with them as
any other smart card, if you lose it. My previous comment stands - don't let
anybody else get hold of your SIM card and/or phone.

The frequencies (from my uni days as I now work as a Unix sysadmin and am not
anything to do with the radio network) are in the Gigahertz ranges. They are
also line of site only. I don't know about health implications, but sticking
anything in the beam will disrupt the path - tree branches are a common problem
when planners underestimate the speed at which some trees grow.
These words are mine, and NOT those of my employer!
