A method ( 200 ) and mobile device ( 120, 130 ) for silently fetching data is disclosed. In one arrangement, the method can include the steps of receiving ( 218 ) a silent fetch request from an originating device ( 120 ) over a wireless communication channel ( 300 ) in which the silent fetch request requests information and checking ( 220 ) the authorization of the originating device. If the originating device is an authorized device, the requested information can be fetched ( 222 ) and transmitted ( 224 ) to the originating device. As an example, the requested information can be fetched from a receiving device ( 130 ) or from a network server ( 140 ) with which the receiving device is associated. As another example, the wireless communication channel can be a traffic channel that supports at least push-to-talk communications.
