Abstract

An apparatus and method for informing a first mobile wireless subscriber identity module which is signed on to a mobile wireless network about further mobile wireless subscriber identity modules that are likewise signed on to a mobile wireless network includes sending a mobile wireless short message to each of the further mobile wireless subscriber identity modules. Based on the delivery to a mobile wireless subscriber identity module of pertinent delivery information, the further mobile wireless subscriber identity modules that are likewise signed on in a mobile wireless network may be determined. A short message may then be sent to the first mobile wireless subscriber identity module including information about which of the further mobile wireless subscriber identity modules are currently signed on to a mobile wireless network.
