• Telephone directory download services exist in wireless telecommunications networks such as the GSM network, an abbreviation of the English terms Global System for Mobile communication. For example, a subscriber to the Orange® telecommunication network can modify the directory of their mobile phone through the server of this company's website.
• the user can for example enter new coordinates in his telephone directory, select coordinates from all the coordinates contained in the telephone directory and activate the transfer of the selected telephone coordinates to the directory of his mobile telephone.
• the transfer of the selected telephone contact details between the website server of this company and the user's mobile phone is done via an SMSC short message server and a download platform.
• SMSC is the abbreviation for the English terms Short Message Service Center.
• the SMSC server assembles the selected coordinates in the form of SMS messages, an abbreviation of the English terms Short Message Service and delivers as many SMS to the mobile phone as necessary for the transfer of the coordinates.
• the telephone coordinates thus transferred are stored in place of the telephone coordinates already recorded.
• the directory thus formed in the mobile phone is stored in the SIM card (Subscriber Identity Module) of the mobile phone.

• This service does not partially modify a directory on a mobile phone. The amount of information transferred is therefore not optimal. If only one coordinate among all the coordinates contained in the mobile telephone directory must be modified or created, all the coordinates in the telephone directory must nevertheless be transferred.
• the user of the mobile telephone can modify the telephone directory stored in his mobile telephone by means of the man-machine interface thereof. In this case, the directory stored in the telephone operator's server is not modified and the two directories are then out of sync. Managing the telephone directory through the operator's server then becomes difficult.
