The method involves transmitting a telephone number (NA) from a user terminal (T1) to a server connected to a network (RR1). The number (NA) is compared with telephone numbers of mobile terminals connected to the network, to read an operator indicator (IO) related to the number (NA). The indicator is transmitted to the terminal in which it is stored and provided to a user to know whether the number (NA) belongs to the network. Independent claims are also included for the following: (1) a system for displaying/providing an operator indicator in a user terminal (2) a portable storage medium with microcontroller for displaying/providing an operator indicator in a user terminal (3) a computer program to be implemented in a portable storage medium with a microcontroller connected to a user terminal, for displaying/providing an operator indicator in the terminal. |
