FOR IMMEDIATE RELEASE

SMITH MICRO REITERATES 2005 OUTLOOK

Aliso Viejo, Calif., March 3, 2005 — Smith Micro Software, Inc. (NASDAQ: SMSI), a developer and marketer of a wide range of software and service solutions for the wireless market, today reaffirmed its prior outlook for the first quarter of 2005, in which it expects a sequential decline in revenues and profitability, reflecting the variability in the wireless data market which is in the early stages of development.

“As we noted in our 2004 year-end conference call last month,” said William W. Smith, Jr., Smith Micro’s President and Chief Executive Officer, “channel inventories of PC cards and related software have been sufficient to meet short term customer demand while additional orders have been deferred.”

“Although there can be no assurances,” Smith added, “we believe that current inventories will be reduced during the first quarter, and that normal growth will resume during subsequent quarters. We still expect year over year increases in both revenue and profitability in 2005.”
