A terminal having one or more domains to which access is controlled by the presence of a removable attachment, particularly a smart card such as a SIM card or UICC. Authorisation data or information relating to such data may be stored on the removable storage device and used as part of a verification test. If the verification test generates a positive verification result, the removable storage device provides an indication of whether the user is authorised to access the one or more domains. Access to the one or more domains is thus controlled such that domains can only be activated when a SIM or other removable storage device is present. The present invention also relates to a removable attachment for use with such a terminal, and a method of providing functions trusted by a third party in the terminal, particularly a terminal for use with a cellular or mobile telecommunications network. |
