Our Invention Intelligent-SIM: multiple company mobile number installed in single SIM is a method and apparatus for a Multiple IMSI Multiple/Single MSISDN (MIMM/MISM) on Multiple SIMs service for a single mobile communications network operator. The invention is also a system includes a Signaling Gateway that includes a MIMM/MISM application and a set of subscriber identity modules (SIMs) for a subscriber, wherein the set of SIMs is registered to the subscriber. The invention is the set of SIMs comprises multiple SIMs, each of which is useable in one or more mobile communication devices, and each of which comprises a different international mobile subscriber identity (IMSI) and also include configuring the set of SIMs and the network such that the subscriber presents a uniform appearance to entities communicating with the subscriber regardless of which SIM is used for the communication, wherein the subscriber can simultaneously carry on a voice call on one SIM and carry on a data session on another SIM. The invented Techniques are relating to operating multi-SIM mobile devices and a UE comprises at least first and second SIMs where the first SIM is configured to communications via a home network or one or roaming networks and the second SIM is configurable for communications via local networks other than the home network. The invented technique also UE is configured the more the one number installed the single SIM to execute a first protocol stack for communications using the first SIM via a home network or a roaming network. The invented technique is the UE is further configured to search for available networks for the second SIM using the first protocol stack and select an available local network for the second SIM using the first protocol stack. This may reduce power consumption and improve communication quality during the search, in some embodiments. FIG. 1 illustrates an example user equipment (UE) according to some embodiments.
