Abstract: In a method for backing up personal data of a wireless communications network subscriber, the data is saved in a mobile communications device and backed up in a server of the network. A first subset of data is prepared from a set to be saved by a SIM card and is transmitted to the server for backing up. In an asynchronous backup mode, after the transmission of a subset of data to be backed up on the server, the backup is delayed for a certain period of time in order to free the mobile device for the user, and the backup is resumed at the end of this period.

Abstract: In a method for saving personal data for a subscriber to a wireless communications network, the data is being memorized in a mobile communication station and saved in a network server by means of a first communication channel and in a first saving mode. A determination is made whether the mobile device may establish a second communication channel and/or has an other mode of saving. If so, communication is opened on the second channel and/or according to the other mode, and the data is saved by means of the second communication channel and/or the other mode.
