Calling Features
The x475's phonebook can handle up to 1000 of your contacts, and you can store up to three numbers per entry, plus an email address. In addition to having a discreet vibrating alert, the X475 supports 40-chord polyphonic ringtones, which means you can really jazz up your incoming calls with cool tunes.

Like all T-Mobile phones, the x475 supports voice mail, caller ID, conference calling, call forwarding, call waiting, call hold, built-in paging, and access to T-Mobile's 411 service.

Traditional text messaging, as well as picture and sound messaging are also supported by the phone. T9 text entry, which is a technology that makes it easier for people to enter words and text on handsets, is built into the unit-- a plus for mobile email and text messaging users.

A number of handy software tools are bundled with the x475, including a voice memo recorder, a calculator with currency converter, a to-do list, a calendar and an alarm clock.
