A mobile device receives via a wireless network an enable message which indicates that a data message has been received and is ready for retrieval. The mobile device then provides an indication which indicates that the data message has been received, and includes a subset of the data message. After providing the indication, the mobile device detects a user-initiated entry into a messaging application. In response to detecting the user-initiated entry, the mobile device examines a setting in a data store which is provided in response to the enable message. If the setting is provided in the data store, the mobile device requests the data message by sending via the wireless network a fetch message and subsequently receives the data message. If the setting is not provided in the data store, the mobile device refrains from sending the fetch message.
