A wireless communications device (100), after determining it can not locally satisfy a request for network data (201), sends a search query or request for data to a proximal device that has a network cache function (202). The proximal device searches for the requested data (203) and if the data is found, then the data is sent to the requesting wireless communications device from the proximal device (206). The data request is sent over a wide area network (204), for example, the Internet, if the proximal device does not have the requested data stored in a memory on the proximal device (204). The wireless communications device stores the data for subsequent use and, if necessary, subsequent provision to a proximal device.
