The NEC G9 was introduced in 1997 and had an alphanumeric 4 x 12 character monochrome display. In addition to the basic phone functions, it included a clock with alarm, a range of call timers and 7 ring tones.
An address book feature was supported in which telephone numbers and associated names could be stored within the SIM card memory only. It could also support the sending and receiving of SMS text messages.
