"The total number of subscribers to cdmaOne cellular phone services from the DDI Cellular Group and IDO Corp. reached 4 million as of Feb. 7, 2000.
"The cdmaOne is a mobile phone system jointly provided by the two telecom carriers. It was launched by the DDI Cellular Group in a limited area in Japan in July 1998. A nationwide network was completed in April 1999.
"The recent increase in the number of subscribers has been accelerating. The figure reached 1 million on May 26, 2 million on Aug. 24 and 3 million on Nov. 23, 1999. This means that the service gained one million new users every three months. It took only about two months, though, for the service to acquire another 100 million new users since it gained 3 million users in late November.
"Despite an increase in the number of cdmaOne subscribers, the cumulative total number of subscribers collected by the DDI Group companies declined slightly because the number of cancellations of personal digital cellular (PDC)-format mobile phone terminals surpassed the number of new subscribers.
"A DDI spokesperson attributed the cancellations to: 1) a fewer number of subscribers every January than other months and 2) some users refraining from purchasing a DDI cellular phone handset until more variety of models compatible with the PacketOne cdmaOne-based packet communication service, which started on Jan. 7, is available in the market.
