The service is the first mobile phone service to be offered between Japan and South Korea and allows users to send and receive e-mail and still pictures as JPEG files between CDMA2000 1x-compatible cell phones sold by SK Telecom and the camera-equipped GPS Kentia operated by KDDI.

This service allows users to send each other pictures taken at live international sporting events held in Japan and Korea and to enjoy many other forms of communication. In this way, the service is expected to deepen interactions between Japan and Korea.

SK Telecom launched CDMA2000 1x services in September 2000 and in September 2001 started 'photo mail', in which images are sent by e-mail.
SK Telecom and KDDI have a global roaming agreement that allows users of au's GLOBAL PASSPORT to use their mobile phones in Korea without requiring any special registration. On May 22, SK Telecom began selling a mobile phone that can be used in Japan and also started full-scale roaming services.
