Provisioning is described for use in communications systems. The provisioning includes receiving a message at an inbox of a device. The message includes information of an electronic location of a source device from which to download the appropriate application and device and user-specific information used for configuration of the application. An application is automatically transferred to the device in response to selection of the received message by a user of the device. The application is automatically installed on the device. The application is auto-started, at which time it self-configures using the original message.
