Vibrate

When mobile phone users don't want their phones to make a noise when they ring, they tend to set them to 'vibrate'. Instead of making a ringing sound upon an incoming call, the mobile simply vibrates as an alert. Most mobile phones contain a mechanical device that enables this to happen.

Video calling

Video calling is a two-way feature which enables people with 3G (Third Generation) phones to see the person they are speaking to when they make a call.

Vocoder

A vocoder, or voice encoder, is a device that encodes and decodes the sound of the voice so that it can be transmitted.

Voice dialling

Voice dialling enables you to speak the name of somebody whose number is saved into your phone and then the phone will automatically call them.

VOIP (Voice over internet protocol)

Voice over internet protocol is a technology which enables telephone signals to be carried (and therefore conversations to happen) via the internet.
