T-Mobile rolling out HSPA+ to 100 Metropolitan Areas in 2010

T-Mobile delivers home broadband-like experiences on-the-go when
surfing the Web, accessing multimedia features, sharing content and

LAS VEGAS and BELLEVUE, Wash. — March 23, 2010 — Today at
International CTIA Wireless 2010, T-Mobile USA, Inc., showcased the
nation’s fastest 3G wireless network on its latest mobile broadband
devices. The company unveiled plans to upgrade its national high-speed
3G service to the High Speed Packet Access Plus (HSPA+) technology,
which will deliver customers data speeds faster than the current 3G
network technology1 . By the end of 2010, T-Mobile expects to have
HSPA+ deployed across the breadth of its 3G footprint, covering more
than 100 metropolitan areas and 185 million people.

T-Mobile hosted live demonstrations of the home broadband-like HSPA+
data speeds on a variety of products including the new Dell™ Inspiron™
Mini 10 with T-Mobile® webConnect™ — T-Mobile’s first netbook — which
launches March 24 online and in T-Mobile stores in select markets.2

“Consumers want a mobile broadband experience that’s easy and as good
as their connection at home on the best wireless devices available,”
said Neville Ray, senior vice president of engineering and operations
for T-Mobile USA. “This year T-Mobile will upgrade its national 3G
network to HSPA+ which will support faster speeds and give customers a
superior wireless data experience when they access their mobile social
network, stream videos or share content. T-Mobile’s network is primed
to deliver the speeds that today’s data users crave.”

T-Mobile successfully launched its HSPA+ network service in
Philadelphia last fall providing customers access to one of the
fastest and most modern wireless networks in the U.S. T-Mobile now has
made HSPA+ commercially available in new markets including major areas
of New York City, New Jersey, Long Island and suburban Washington,
D.C., with deployment in Los Angeles coming very soon.

The company will continue to aggressively expand the availability of
HSPA+ in additional 3G markets, putting the necessary backhaul
capacity in place to support the very fast speeds. Today, its 3G
high-speed data network covers more than 206 million people.

T-Mobile’s HSPA+ network is outperforming competing 3G wireless
networks with speeds up to three times faster. Blazing fast actual
peak download speeds3 were demonstrated today in Las Vegas using both
new and current mobile broadband devices, including the T-Mobile
webConnect Rocket™ USB Laptop Stick, the first HSPA+ capable device
from a national U.S .wireless carrier; the Dell Inspiron Mini 10; the
HTC HD2; the Motorola CLIQ XT™ and the T-Mobile myTouch® 3G.

“The webConnect Rocket and Dell Inspiron Mini 10 are the latest mobile
broadband products that deliver real customer benefits with faster
speeds available today,” said Cole Brodman, chief technology and
innovation officer for T-Mobile USA. “And the great thing about
T-Mobile’s 3G network evolution is its backward compatibility — most
of our 3G smartphones will deliver a better mobile Web experience.
Customers don’t have to spend money on a device upgrade, which is a
rarity in consumer electronics.”
