Mass production from Microelectronica facility to include 1-gigabyte mSIM MegaSIM® series high-capacity SIM cards by year’s end

SUNNYVALE, Calif., Sept. 27, 2006, msystems (NASDAQ: FLSH), a leader in smart personal storage, today announced the availability of high-capacity mSIM MegaSIM cards through its Microelectronica subsidiary.

In addition to the currently available 128-megabyte, 256-megabyte and 512-megabyte msystems MegaSIM SIM cards, 1-gigabyte MegaSIM products, planned for commercial availability by the end of the year, will be mass produced at the Company’s Microelectronica facility in Spain.

“Leveraging the know-how and manufacturing capabilities acquired through Microelectronica, we are able to deliver our first commercial, high-capacity SIM cards manufactured and offered by msystems,” said Simone Cavallo, general manager of the Mobile Network Operators division at msystems. “Our 1-gigabyte card represents a breakthrough in SIM card technology. This unique achievement further strengthens our leadership and innovative position in the high capacity SIM market. With the wide range of SIM card capacity choices available from msystems and its Microelectronica subsidiary, mobile network operators can now begin to implement new business models and capitalize on new revenue streams.”

The unique features of MegaSIM enable the creation of new revenue opportunities for mobile network operators (MNOs) and the delivery of increased value to subscribers through new services, content and applications. For example, storing downloaded data directly onto the SIM card, MNOs can control content distribution with built-in DRM support associated with the customer’s unique subscriber ID. MegaSIM is well suited for DRM related solutions and provides a high level of flexibility to the subscriber. The new 1-gigabyte SIM card will allow users to securely store thousands of songs or hundreds of high resolution photos, as well as personal productivity data and other content of their choice.
