The invention relates to a method and an arrangement against fraudulent use in a telecommunications network. The invention is based on the idea that at least one fraud profile identified by an identifier is created and the identifier is included in the subscriber data of some subscribers. Based on this identifier the fraud restriction parameters of the subscriber are retrieved from the subscriber's fraud profile, and these fraud restriction parameters are used in detecting and indicating possible fraudulent use. The fraud restriction parameters include values for different service limits, such as the maximum number of call forwarding re-quests and/or the maximum number of location updates during a certain period, and possibly at least for some features an action parameter related to a service limit and implemented when the service limit is reached.
