PRESS RELEASE                                                   January 18, 2006

Sony Ericsson reports record shipments, sales and profits

Highlights:

   - Record year due to strong 2H 2005
   - 3 million Walkman(R) phones shipped since launch
   - Further strengthened portfolio with 3G and entry level handsets

The consolidated financial summary for Sony Ericsson Mobile Communications AB
(Sony Ericsson) for the fourth quarter ended December 31, 2005 and full-year
2005 are as follows:


                                  Q4 2004   Q3 2005   Q4 2005   2004   2005
                                                         
Numbers of units shipped (million)   12.6      13.8      16.1   42.3   51.2

Sales (EURO m.)                     2,005     2,055     2,310  6,525  7,268

Income before taxes (EURO m.)         140       151       206    486    514

Net income (EURO m.)                   55       104       144    316    356



Units shipped in the quarter reached 16.1 million, a 28% increase compared to
the same period last year and a 17% increase sequentially, in-line with the
sequential growth in the market. Sales for the quarter were Euro 2,310 million,
representing a year-on-year increase of 15%. Income before taxes was Euro 206
million and net income was Euro 144 million, which represents a year-on-year
increase of Euro 66 million and Euro 89 million respectively.

The fourth quarter witnessed very strong sequential market growth which Sony
Ericsson matched, resulting in a record quarter in terms of volumes, sales and
net income for the company. The second half of 2005 was particularly strong due
to the success of hit model phones in both the imaging and music product
categories. A highlight of Sony Ericsson's year was the global success of
Walkman branded music phones such as the W800, W600, W550 and the W900, which
have established Sony Ericsson at the forefront of expanding consumer choice in
how people enjoy digital music on the move. Since the first Walkman phone was
launched in volume in August, Sony Ericsson has shipped 3 million Walkman
branded units.

"This was another solid quarter for Sony Ericsson, and has enabled us to finish
the year with great momentum. We are now seeing the benefit of our earlier
investments in R&D which have enabled us to expand the product line-up and
successfully appeal to new consumers with products like the Walkman phone
series. At the same time, investment in developing the Sony Ericsson brand
during 2005 is increasingly supporting our position in the market place," said
Miles Flint, President of Sony Ericsson. "In the fourth quarter we continued to
announce exciting new products at a variety of price points; from high-end 3G
products like the new W900 3G Walkman phone to attractive mid-tier clamshell
phones like the Z520 model to lower-priced essential phone models such as the
J230, J210 and Z300 that will appeal to consumers who want a simple and stylish
handset."

During the fourth quarter Sony Ericsson announced an approximately $14 million
investment to purchase a controlling 64.5% stake in Beijing Suohong Electronics
Co, Ltd (BSE) from Sony China, in order to strengthen its in-house manufacturing
processes. Sony Ericsson's majority ownership in BSE will be consolidated into
Sony Ericsson from the first quarter of 2006.

Walkman(R) is the registered trademark of the Sony Corporation.
