Abstract
A mobile telecommunications apparatus () is initialised with settings for use with one of a plurality of different operator networks. The apparatus, such as a mobile telephone handset has a micro-controller () with an associated non-volatile memory () that is pre-loaded with data comprising a plurality of variant packs (VP) for controlling the settings of the apparatus for use with individual networks. The handset also receives a subscriber identity device (SIM) that carries network identity data corresponding to the network to be used by the subscriber. The micro-controller () performs an initialisation procedure when the SIM is fitted to a receptor (), to select at least one of the variant packs (VP) in dependence upon the network identity data from the SIM, and to set the settings of the apparatus in accordance with the data from the selected variant packs. The non-selected packs are not revealed to the subscriber.
