An accelerated access system for a computing device, in which the computing device is connected to a first data network, such as the Internet, via a second data network such as a wireless telecommunication network. The system comprising a server for downloading data from the first data network before that data has been requested by a user of the computing device and a cache for storing the downloaded data. For example, during browsing of the Internet by a user of the computing device the server downloads data linked to an Internet site being displayed by the computing device for storage in the cache. Then when a user subsequently requests the data stored in the cache it appears on the screen of the computing device faster than it would take to access it from the Internet. The system is located between the first data network and the second data network so that not all of the data downloaded by the server and only requests for data made by a user of the computing device are transmitted over the second data network.
