Abstract: The various embodiments herein provide a method and system for operating a multi-subscriber identity module (SIM) mobile device. The method includes identifying a common suitable public land mobile network (PLMN) cell between a first radio frequency (RF) unit and a second RF unit of the mobile device. The first RF unit and the second RF unit of the mobile device are currently camped on different PLMN cells. Further, the method includes enforcing at least one of the first RF unit and the second RF unit to camp on said common suitable PLMN cell and disabling one of the first RF unit and the second RF unit when at least one of the first RF unit and the second RF unit camps on the common suitable PLMN cell.

Abstract: A method and system for operating a multi-Subscriber Identity Module (SIM) mobile device are provided. The method includes determining whether at least one Registered Public Land Mobile Network (RPLMN) among a first RPLMN of a first SIM and a second RPLMN of a second SIM of the multi-SIM mobile device is unavailable to the multi-SIM mobile device when the multi-SIM mobile device triggers a Public Land Mobile Network (PLMN) search, identifying a common PLMN, from a first PLMN set associated with the first SIM and a second PLMN set associated with the second SIM, in response to determining that the at least one RPLMN among the first RPLMN and the second RPLMN is unavailable, and camping on the common PLMN by the first SIM and the second SIM after acquiring camping information of the common PLMN.
