Abstract

The present invention consists of a method of authorizing access to a cellular mobile radio network from a simplified mobile telephone, simplified in particular in that it does not include a reader adapted to receive a subscriber identification module. According to the invention, access to the network is made possible in particular by a service initialization phase during which a subscriber to the network supplies to the network data representing a serial number specific to the simplified mobile telephone, for example its IMEI number, and data characteristic of each telephone number that can be called from the simplified mobile telephone, all of the data being stored in a data base of a server of the network in a private directory associated with the simplified mobile telephone.
