Abstract: The method of the invention for automatic selection of configuration profile to a mobile phone. One or more configuration profiles are predefined in the mobile phone and one configuration profile is defined in a card inserted in the mobile phone. The method has the steps of switching on the mobile phone, comparing the configuration profile of the card with the configuration profile information in the mobile phone, and selecting a configuration profile to the mobile phone as a consequence of the comparison.

Abstract: The roaming of mobile equipment between a home network and foreign network is managed. The roaming behavior is based on the contents of control files saved in the mobile equipment of the subscribers. A list of networks to be used in a priority order in a roaming situation is defined in the control files. The management application checks the current roaming setting for the mobile equipment and the desired roaming behavior for the location that the mobile equipment roamed into. As a result of the comparison, the management application adjusts the roaming setting to be in accordance with the desired roaming behavior.

Abstract: The method relates to the management of roaming of mobile subscribers between a home network and foreign networks. The roaming behavior of a mobile terminal is based on roaming settings in the form of contents of different control files saved in the mobile terminal of the subscribers. A first file contains a list of networks to be used in a priority order in a roaming situation and a second file contains information about the last network the subscriber was registered in. The method starts with roaming of the subscriber from one network to another network, and checking the current roaming setting for the subscriber. If the network that the subscriber roamed into does not correspond to the highest priority network, the subscriber is moved to a preferred network corresponding to the priority order of said list.

Abstract: In the method of the invention for the management of roaming of mobile subscribers, which are roaming between a home network and foreign networks, the roaming behavior is based on the contents of control files saved in the mobile equipment of the subscribers. A list of networks to be used in a priority order in a roaming situation is defined in said control files. When a subscriber is roaming management application, which checks the current roaming setting for the subscriber and the desired roaming behavior for the location that the subscriber roamed into, and as a result of the comparison, when necessary, it adjusts the roaming setting to be in accordance with said desired roaming behavior.
