A provisioning system for receiving configuration changes to and queries of settings on a mobile device. The provisioning system may include a router, configuration manager and one or more configuration service providers. The router component is responsible for receiving messages delivered to the mobile device and parsing the messages into requests for information. The configuration manager component is responsible for determining what configuration settings are affected by the message and for processing the requests within the message. The configuration manager component may implement one or more configuration service providers to perform the actual request processing. The configuration manager component may additionally compose a response document to return in the event that a response has been requested in the message.
