Ni kwamba, haya makampuni yame-outsource network department kwa NOKIA SIEMENS NETWORKS (NSN), sasa NSN wao wameamua kuwapa contractors mbalimbali towers zote kwa maintenance............ i.e contractor mmoja wa NSN anafanya maintenance kwenye towers za VODA na Airtel. Kwa hiyo muunganiko ninaouona mimi ni ulke uliofanywa na NSN na wala si VODA NA AIRTEL. By the way VODA na AIRTEL DO NOT CARE WHO THE HELL IS DOING MAINTENANCE TO THEIR TOWERS, ALL THEY CARE IS NETWORK AVAILABILITY OF ABOVE 99.98%
