In a method for downloading software from a mobile network operator to a mobile phone user, the downloaded software can be new network services or user specified applications software or user specified information, written as Java classes capable of running on a Java Virtual Machine. All the Java classes can be continuously broadcast at a relatively modest data rate. In an enhanced mode a list of services available for downloading is broadcast over the network more frequently then the actual services themselves. The user then selects which service he wants, and only that one is downloaded. Payment can be 100 on a subscription or pay-per-use basis. The method could also be adapted to work with one of the new digital broadcasting platforms such as DAB or DVB as a means for delivering the Java classes.
