Message Notifications
When you receive a message, your phone notifies you with text on the display, a notification tone or vibration, and by flashing the Boost logo backlight slowly.
You can access the message or dismiss the notification.
If you dismiss the notification, the message is not deleted. It can be accessed through the message center.
If you are not on a phone call when you receive a message, your phone sounds a notification tone every 30 seconds until you access the message or dismiss the alert.
If you are on a call when you receive a message, your phone may sound a notification tone during the call or after you end the call, depending on how you set your notification options.
