PRESS RELEASE                                                  October 17, 2005

Hit Models Boost Sony Ericsson Performance

Highlights:

             - Solid growth & market share gain
             - Increased R&D investment generating expanded portfolio
             - Strong demand across portfolio

The consolidated financial summary for Sony Ericsson Mobile Communications AB
(Sony Ericsson) for the third quarter ended September 30, 2005 is as follows:





                                   Q3 2004    Q2 2005     Q3 2005
                                                    


Numbers of units shipped (million)    10.7       11.8        13.8

Sales (EURO m.)                      1,678      1,614       2,055

Income before taxes (EURO m.)          136         87         151

Net income (EURO m.)                    90         75         104




Units shipped in the quarter reached 13.8 million, a 29% increase compared to
the same period last year and a 17% increase sequentially, substantially higher
than sequential market growth. Sales for the quarter were Euro 2,055 million,
representing a year-on-year increase of 22%. Income before taxes was Euro 151
million and net income was Euro 104 million, which represents a year-on-year
increase of Euro 15 million and Euro 14 million respectively. The company
continued to increase investment in marketing and R&D to support the expansion
of the portfolio going forward.

Sony Ericsson began to reap the rewards of earlier increased investment in R&D,
expanding the product portfolio with hit models like the K750, the award-winning
2 megapixel, auto-focus camera phone, the first WalkmanTM phone, the W800, which
has been exceptionally successful, and the K600 series, which has brought Sony
Ericsson UMTS handsets into the mid-tier price category. The company grew faster
than the market during the quarter with the popularity of higher-end phones
having a positive effect and raising the profile of more affordable, volume
models like the T290, J210 and K300. Average Selling Price (ASP) rose during the
quarter reflecting the proportion of higher-end products entering the product
mix.

The global handset market continued to grow faster than expected, and Sony
Ericsson is upgrading its global market outlook for 2005 to over 760 million
units.

"This has been a good quarter for Sony Ericsson, proving that our strategy of
expanding the product portfolio upward into best-in-class imaging, music and 3G
products while increasing the number of more affordable and attractively
designed volume models is paying off. We are increasingly benefiting from the
opportunities created by the joint-venture, and with three new Walkman(R) phones
shipping in the fourth quarter (W550, W600, W900), we are optimistic that Sony
Ericsson can set the standard in music as well as imaging going forward," said
Miles Flint, President of Sony Ericsson.
