Sound and Alert System
Sound options on the NEC N331i are minimalistic. The phone does not include a loudspeaker or a 3.5mm audio jack, focusing instead on downloadable polyphonic ringtones and vibration alerts to notify users of calls and messages. This was a common feature of early phones where customization was limited to a selection of downloadable tones without music playback capabilities.
