>Touch on this setting and you should see a listing of available notification sounds in your phone to select from.

Select notification sound and SAVE


Keep in mind , if you select a long sound file, ( a ringing tone)  it will continue until you actually look at the message on your phone.


*Note: Currently iOS devices do not allow you to change the notification sounds, this is currently due to app restriction within the iOS platform.
