Launched on April 1, subscribers of the CDMA2000 1x service numbered 334,100 by April 30, 695,700 by May 31 and topped the one million mark in under three months after the launch.

The CDMA2000 1x service has a wireless Internet environment and allows downstream data transmission at speeds of up to 144kbps and upstream data transmission at 64kbps with the Internet connection service EZweb and various other providers.

The service area covers 43 municipalities in Japan, and KDDI plans to extend this to cover 90% of the population of Japan by the end of 2002.

Handsets that are compatible with CDMA2000 1x include the GPS Keitai (A3000) series, which have a highly-accurate location information system that uses signals from global positioning system (GPS) satellites, the camera-equipped GPS Keitai (A3012CA) and the inter-changeable GPS Keitai (A3014S), as well as six other models in the simple and user-friendly A1000 series.

According to a June 2002 report from the CDMA Development Group, the total number of CDMA2000 1x and CDMA2000 1x /EV-DO subscribers has exceeded 10 million.

CDMA2000 1x services are currently being offered by 15 companies in seven countries in Asia, North America and Europe, including Japan, South Korea, the U.S., Canada, Puerto Rico, Brazil and Romania. The CDMA2000 1x/EV-DO service, capable of 2.4Mbps high-speed data transmission, is now being marketed in South Korea. As more companies roll out both of these services they are expected to attract more more and more subscribers around the world.
