MetroPCS Introduces ChatLINK(TM)

The First PTT Product That Can Connect Friends and Family
Regardless of Their Wireless Service or Landline Provider
RICHARDSON, Texas--(Business Wire)--
MetroPCS Communications, Inc. (NYSE: PCS), the nation's leading
provider of affordable unlimited wireless communications service for
one flat rate, today introduced ChatLINK(TM), a new Push-To-Talk
feature that enables customers to quickly link up and chat with their
friends and family across different networks at the same time.
MetroPCS is the first wireless carrier to offer this type of service
between users of different wireless carrier and landline networks.

ChatLINK(TM) allows MetroPCS subscribers to create a network of up
to 10 individuals and connect with them in walkie-talkie like
discussions at the press of a button. Similar to instant messaging,
subscribers are able to add contacts and view their availability with
a series of presence icons indicating that they are online, offline,
silent, or in do not disturb modes.

"ChatLINK(TM) is a social networking tool. It allows our
subscribers to talk to groups of friends and family at the press of a
button and they can invite any friend to join with any phone," said
Roger Linquist, president and CEO, MetroPCS Communications, Inc.
"ChatLINK(TM) is another example of our commitment to providing
innovative and fun, affordable and unlimited wireless services to our
subscribers and giving them options to expand their unlimited plan."

A ChatLINK(TM) session begins when a subscriber sends an
invitation to an individual or group to join a session. When the
recipient receives the invitation they simply follow the instructions
to join the session and press any key to begin speaking. Subscribers
can invite any domestic phone number to a ChatLINK(TM) session.
MetroPCS' allows subscribers unlimited use of ChatLINK(TM) for $5 a
month, a significant value over other carriers. ChatLINK(TM) is
available in both English and Spanish interfaces.

wireless communications service for a flat rate with no signed
