I have received a circular through official channels at my work relating to a "scam" whereby a caller requests phone users press#90 or #09. This allegedly allows access to the user's SIM card. Also, that a caller "Xalan" infects sim cards with a virus.
Allegedly, this has been confirmed by Nokia and Motorola.
I have refused to dissemminate this info. further as I believe it is bogus. Can you confirm?
