All 9 Series phones are preinstalled with i-appli software required to use DoCoMo's DCMX credit card.

The series includes Japan's first HSDPA-compatible handset, the N902iX HIGH-SPEED. HSDPA is a new high-speed packet-transmission technology for downlinks at up to 3.6Mbps, or 10 times faster than current FOMA handsets.

All models in the 9 Series have music players. Some are also compatible with DoCoMo's Chaku-Uta Full service for downloading full music tracks from i-mode sites, as well as Music Channel for programmed, automatic downloading of music from i-mode sites during the night (N902iX HIGH-SPEED), and Windows Media Audio files (F902iS).

Other features common to many of the new 9 Series handsets include:

• Extensive security - Data Security Service enables phonebooks to be stored on the DoCoMo network.
• Omakase Lock enables users who lost their phone to telephone a 24-hour call center to have the phone's smart card and personal data locked immediately.

• Decorative Deco-mail graphics can be automatically inserted in e-mail signatures and subject lines.
