I like to add that I am mainly interested in technical explanations of 
the phenomena, i.e. whether
it is indeed true, and how, that the SIM card in my mobile phone got 
manipulated, and personally
deem it not favorable, nor essential, realistic, etc. to conjecture in 
our group on the motivations
behind such manipulations, if these indeed happened,

BTW, it's a chance coincidence that I just saw elsewhere a post saying 
that the poster got a call
but heard no voices of the caller but only certain environmental noises, 
i.e. likely to be also a
call automatically done by a mobile phone of somebody else.
