Indosat Selects Altobridge's Wireless Community Solution

Altobridge lite-site(TM) - The Solution of Choice for Pan-Indonesian Roll-out

KERRY TECHNOLOGY PARK, Ireland, February 9, 2011 - PT Indosat Tbk - the second largest mobile operator in Indonesia, has
selected Altobridge, a leading provider of mobile telecommunications
solutions, as its supplier of choice to bring mobile connectivity to remote
communities across Indonesia.

Deployment of the Altobridge lite-sites(TM) is already underway amongst
previously unconnected communities in West Sulawesi. The low-cost,
solar-powered Altobridge solution will bring voice, SMS and mobile data
connectivity, for the first time, to communities and enterprises across
Indonesia.

Steve Hobbs, Indosat Director and Chief Technology Officer, said,
"Bringing mobile connectivity to thousands of unconnected communities in
Indonesia is part of our vision to provide products and services, which
enhance the quality of life of the communities we operate in.

"We chose the Altobridge lite-site(TM) because it enables us to optimize
our capital budget, while, operationally, it minimizes our backhaul costs
and, equally important, it is power efficient and ideally suited for solar."

Aoife Sexton, President Remote Community Solutions at Altobridge, said,
"We specialize in delivering a low capital cost and low operational cost
wireless network solution for the world's unconnected communities and
enterprises. We are delighted to have been chosen by Indosat in this hugely
important growth economy."
