foremost innovator among 4G^LTE wireless service providers, MetroPCS

offer its RCS services under the GSMA-licensed joyn brand. Based on the GSMA

Included in all 4G^LTE rate plans and RCS-enabled smartphones, joyn by
MetroPCS will bring everyday mobile-to-mobile communication to life. Today,
mobile users have a fragmented experience requiring the use of multiple,
separate applications and logins in order to use enriched services and share
content. joyn offers a simple and personal way to connect with friends and
family in real time, by showing how contacts can be reached and which
multimedia capabilities in chat, content transfer or video share are available
for each contact – all with just one click from the user's address book.

"MetroPCS' goal has been to innovate for the purpose of delivering an
exceptional quality of experience to our customers and to consumers who demand
value and the ability to do more with their mobile service," said Roger
Linquist, CEO and Chairman of MetroPCS. "As the first 4G LTE carrier in the
world to offer RCS, we are excited to join the global community of operators
implementing the RCS standard and we are proud of our team and partners who
were critical in building this capability that will evolve and expand over the
next year."
