A cellular communication device has one or more access modes which allow reading and writing of data, for example to change its settings, for example passwords and even the entire operating system and also permitting access to personal information such as the user's telephone book. To prevent cloning and like illegal access activity, the device is configured by restricting access to such data access modes using a device unique security setting. The setting may be a password, preferably a one-time password, or it may be a unique or dynamic or one time configuration of the codes for the read and write instructions of the data mode. There is also disclosed a server, which manages the security settings such that data mode operates during an active connection between the device and the server, and a secure communication protocol for communicating between the server and the cellular device. |

1. A system comprising:
a plurality of cellular communication devices (CCDs), each CCD associated with a unique identifier (NCUI), configurable settings, and an operating system, each CCD comprising an access restrictor that, in response to a received password, switches the CCD into a data mode in which the CCD allows reading and writing into the settings thereof and updating and changing the operating system thereof; and wherein the CCDs permit the reading and writing into settings thereof and the updating and changing the operating system thereof only in the data mode, a client reprogramming device (CRD) able to communicate with each one of the CCDs; and a remote data server (RDS) connected, over a secured communication link (SCL), to the CRD, wherein the RDS keeps all of the NCUIs of all of the CCDs and is further configured to generate a password for switching a CCD into the data mode, for each one of the CCDs, based on a respective NCUI, and wherein the CRD is configured to: (i) receive the NCUI from a CCD, (ii) transfer a request for a respective password for the received NCUI, over the SCL, to the RDS, (iii) receive the respective password from the RDS over the SCL, and (iv) apply the password to the access restrictor of the CCD, to switch the CCD into the data mode. |
