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.
