Chief Adviser of the interim government Fakhruddin Ahmed formally inaugurated mobile phone network in Chittagong Hill Tracts on Thursday by talking to his two special assistants at Rangamati Hill District from northeastern Dinajpur, where he went to inaugurate Boro harvest and procurement drive.

"The mobile phone network will contribute to socio-economic development of the people of three hill districts. We have given special attention to the socio-economic development of the people in the hills," officials quoted Ahmed as saying as he talked to his special assistant Raja Debashish Roy, also the chief of the major Chakma tribe.

The network was launched in six weeks since Ahmed promised to bring the rugged hills under the cell phone connectivity during his visit to the region.

Officials said initially the municipal areas of the three hill districts of Rangamati, Khagrachhari and Bandarban would be included under the cell phone network while it would be spread in other parts of the tribal inhibited CHT, which constitutes one tenth of Bangladesh in terms of area.
