The device is typically a mobile device and the requested items can be key words making up a search request or can be web site names indicating web sites of interest to the user. In response to the request, data listings having items generating a match with the requested data item are identified and data indicative of a network location corresponding to the or each matched data item are retrieved. In addition data indicative of an amount of data and a resource allocation associated with the set of data accessible via the network location are retrieved and these data, together with a network subscription associated with device and the amount of data, are used to evaluate actual usage of network resources when accessing the set of data. |
