How do I use Voice Messaging?
Voice Messaging allows you to instantly communicate with a contact or group chat. It provides an enriching chat experience, and you can count on it to deliver important and time-sensitive messages. As such, all Voice Messages are downloaded automatically.
Sending a Voice Message
To send a Voice Message, simply hold down on the space key of the keyboard. On full touchscreen phones, tap and hold the text entry box.
To cancel sending the Voice Message, press and hold the end key before the message finishes uploading.
A really cool and innovative feature of Voice Messaging is that when your Voice Message has been played on the recipient's phone, the microphone icon will turn blue.
