Systems and techniques are provided for delivering image content and other caller-specific data in real-time with an incoming voice call for a mobile device configured to receive voice calls and data through separate channels of the mobile communication network. In response to receiving a call request from an originating device for a voice call to a recipient mobile device, it is determined whether a database in the mobile communication network includes a caller-specific image associated with a caller at an originating mobile device. When the database is determined to include the caller-specific image, the image is sent via a network data connection to the recipient mobile device for display as part of an incoming call notification at the device. The voice call from the originating mobile device is allowed to proceed to the recipient mobile device, only after the caller-specific image is sent to the recipient mobile device.
