Abstract
The invention relates to a telecommunication method and a system suitable for same for establishing a connection with a mobile station, for example a GSM mobile telephone, of a subscriber located in a visited public land mobile network. According to said method the calling mobile subscriber in the visited public land mobile network prepares a short message, for example an unstructured supplementary service data message with the desired destination number and sends said message, which is then transmitted to a callback computer which establishes a connection between the calling mobile subscriber and the desired destination number. A connection to a called mobile subscriber in a visited public land mobile network is established by a callback computer whose number is assigned to the called mobile subscriber in the home location register. Before a connection is established the remaining credit and airtime of the mobile subscriber is verified in a prepaid module connected to the callback computer, on the basis of prepaid amounts or with the aid of at least one schedule of telephone tariffs and on the basis of a location of said subscribers stored in the home location register of the home public land mobile network.
