A system and method that provides data messages to a passive device. A
passive device, for example watch, is registered together with the
telephone number of a cellular telephone of a subscriber to the data
message service. Since the cellular telephone periodically transmits a
beacon signal, the wireless network knows its cell location. Accordingly,
the system determines the cell location of the cellular telephone and
establishes a communication of the subscribed data to the watch via the
local cellular provider for the same cell location as that of the
subscriber's cellular telephone.
