Hutchison Telecom has cut the cost of using its CDMA (code division multiple access) network to levels that make it among the cheapest in Hong Kong. The move reflects increasing competition within the industry and Hutchison's desire to keep using the network as its engine of subscriber growth. Hutchison Telecom managing director Dennis Lui said the CDMA network, known as Xin Gan Xin, had about 230,000 subscribers at present. 'We are aiming for 400,000 by the end of the year,' he said. The network's lowest monthly tariff is now $120 per month for 120 minutes of free air-time. Previously, it charged $190 for 100 free minutes. The move brings Hutchison's lowest CDMA tariff into line with the People's Telephone PCS (personal communications services) network. Its base lowest charge is $1 per minute, with no monthly tariff. Next cheapest is Mandarin's Sunday network charge with $138 for 100 minutes on its PCS network. All the networks use different tariff patterns at higher levels of usage. After an introductory offer on its Everyday PCS network of $68 for unlimited use, Hutchison is putting up the cost of using that network to $120 per month for 120 minutes. The introductory offer finishes at the end of this month. The PCS operation has 33,000 subscribers. Subscriber growth in Hutchison's most established operation, its GSM (global system for mobile communications) network, has slowed considerably. Mr Lui said it had more than 360,000 subscribers.
