An effective possibility for making collect calls available is provided by a method for registering and connecting a collect call characterized in that a calling mobile station sends a USSD message concerning a desired collect call with another mobile station to an intelligent network service in a communication network. The service in the communication network sends a text message with an inquiry concerning the transfer of costs for the collect call to the other mobile station. It is then determined by the other mobile station whether there is a willingness there to accept transfer of the costs of the collect call, and the other mobile station will call back the calling mobile station if cost transfer is has been accepted.
