Hi,
Although the phone number will not be traceable to you. The system
knows your phones IMEI number, which is hardware/firmware bound
to GSM digital phones. They can put 2 and 2 together and find that
the IMEI number usually corresponds to your number.
Unless you can reprogram the IMEI, I wouldn't trust a pre paid card.
I think the IMEI number is also used as part of the encryption key.
or buying the optus card package, aus only, for about $70-00, which
gives
you a simm card and sixty dollars worth of calls.. phone is not
supplied.
hurry though, as the feds want these cards to be name registered, as
they >can
presently be bought with no ID.. great for those untraceable
dealings...
