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.
