World's First Rich Communication Suite-Based Service Now Live in South Korea

KT, SK Telecom and LG Telecom join forces to provide new enhanced services for
customers incorporating GSMA's Rich Communication Suite key features

LONDON, June 30 /PRNewswire/ -- The GSMA today announced that the world's
first interoperable enhanced communication service incorporating key elements
of the GSMA's Rich Communication Suite (RCS) specifications is now a live
commercial service in South Korea. The GSMA's RCS initiative is supported by
some of the world's leading handset vendors, core network vendors and mobile
operators including KT, and SK Telecom, who joined the initiative to provide
an interoperable service solution in South Korea.

The services offered by the three South Korean operators include KT's 'show
moov', SK Telecom's 'Mobile Messenger' and LG Telecom's 'OZ messenger', and
commercialise key features of RCS such as phonebook driven buddy lists,
presence capability that includes taglines and status, and voice calls and
messaging.

KT's 'show moov' client application is available for mobile and PC platforms,
so users can access RCS services from mobile and fixed terminals, which is a
key feature of the RCS specifications developed by the GSMA. Also, SK Telecom
and KT are actively collaborating with fixed line services. For instance, KT
'show moov' is integrated with one of Korea's major portal's e-mail, search
services and SK Telecom' s mobile messenger is linked with one of Korea's most
popular messenger 'Nate On Messenger'.

"We are delighted that three leading mobile operators in South Korea, KT, LG
Telecom and SK Telecom, have together launched the world's first commercial
service incorporating key elements of the GSMA's Rich Communication Suite,"
said Michael O'Hara, CMO at the GSMA. "We live in a world where users want to
access and share information at any time, any place and from any device, and
the GSMA's RCS initiative provides operators with the ability to launch a
variety of new and enhanced communication services that fulfils this need."

The GSMA's RCS initiative will provide an exciting, feature-rich portfolio of
communication services that operators will be able to offer their customers.
RCS unleashes the communities hidden in a user's phone book and with one
simple click, the 'always on' user can share lifestyle experiences and
emotions using rich content such as images and video amongst their closest
'buddies'.

Developed by the collaborative efforts of leading mobile operators, vendors
and telecommunication companies, RCS service features for the end user include
an 'Enhanced Address Book' with presence and capability indications, 'Rich
Call' facilities to exchange different types of content during a call and
'Rich Messaging' that expands on traditional instant messaging.

SK Telecom and KT are active participants in the GSMA's RCS initiative and
their newly announced, interoperable commercial services in South Korea will
provide significant opportunities for feedback, which will assist the creation
of new 'use cases' as the RCS specification focus moves into the PC to mobile
domain.

Further announcements on RCS trials and launched commercial services are
expected around the world in the coming year.
