1.8 Million lines GSM network, MSS adopted ZTEs

WCDMA R4 CN based on V3 platforms, finished at the

end of 2005.

1 Million lines WCDMA, covering the capital, Tripoli andthe other 13 main cities, can serve 90% of the population

in Libya.

Fast growth of subscriber: The number of subscribers

broke through 300,000 at the end of 2006.

Network ScaleNetwork Scale

R4 architecture; GSM and WCDMA hybrid network;

support 2G/3G handover and roaming

Both Pre-paid and Post-paid services are available

Thousands of dual mode mobile subscribers can

smoothly migrate to 3G network

Within 3 months, finished the construction and
