Systems and methods are provided for enabling dual subscriber identity module (SIM) card usage for accessing packet switched services/networks. Each of the dual SIM cards operate in an always on mode and can be used to establish and maintain data connections over which the packet switched services/networks can be engaged. The dual SIM cards can be used in the aggregate or separately according to dynamic selection or fixed/mapped associations between an application requesting to access the packet switched services/networks and one or more of the dual SIM cards.

A method of operating a moving object having a plurality of identity devices is provided. The method includes generating data in the moving object, transmitting first data of a plurality of data to a first node through a first identity device of the moving object and transmitting second data of the plurality of data to a second node through a second identity device of the moving object, receiving the first data from the first node and receiving the second data from the second node, and operating the moving object based on the first data and the second data.

Provided are an electronic device and a control method for providing call continuity in a weak electric field environment. The electronic device according to various embodiments of the present document comprises: a processor; a memory operatively connected to the processor; and a wireless communication circuit operatively connected to the processor and the memory, wherein the processor can control the wireless communication circuit such that the electronic device receives a wireless signal for executing a call with an external electronic device through a first network, check the state of the wireless signal received through the wireless communication circuit, control, on at least a partial basis of a result of checking the checked state of the wireless signal, the wireless communication circuit such that an authentication request for performing the call is transmitted to a second network connected to the electronic device, and control, on at least a partial basis of a result of the authentication request, the wireless communication circuit such that the wireless signal, which is transmitted from the first network, for performing the call with the external electronic device is received through the second network.

A method for optimizing PWS message reception in multi-SIM multi-standby UE and UE thereof are disclosed. In an embodiment, the method includes receiving a scheduling information of SIBs containing a PWS message from a first network entity and the scheduling information of SIBs containing the PWS message from second network entity. The method checks whether a PWS message identifier is present in a primary CBS configuration list of the first SIM and if so, receives the SIBs based on the scheduling information. The method checks whether the PWS message identifier is present in a secondary CBS configuration list of the second SIM, and terminates reception of the SIBs by the second SIM when the PWS message identifier is absent. A CBS notification is sent by the first SIM, containing the PWS message to a CBS controller in the absence of error while receiving the PWS message from the SIBs.

The disclosure relates to 5G or 6G communication systems to support a higher data rate after 4G communication systems, e.g., LTE. The disclosure provides a method performed by a user equipment (UE) in a wireless communication system, the method comprising: receiving, by a modem from an embedded universal integrated circuit card (eUICC), a first message including at least one of information related to whether eUICC functionality is supported and information related to whether multiple enabled profiles (MEPs) are supported; and determining, by the modem, to operate with an MEP function based on at least one of the received information related to whether the eUICC functionality is supported and information related to whether the MEPs are supported. Further, various embodiments of the disclosure provide a method and device for providing a dual-SIM function even in a UE equipped with a single eUICC in a wireless communication system.

A system for high-availability secure communication between a mobile terminal and an application server. The terminal is connected to a communication box having at least three physical communication interfaces, a first interface used for communicating with the terminal. The communication box connected to an access server by first and second links through corresponding first and second physical remote communication interfaces. The application server connected to the access server. The terminal and the application server communicating through the communication box and the access server using one of two previously established links. The communication box is the network gateway of the terminal. The communication box: maintains a local routing table based on the routing performance of at least one physical remote communication interface; maintains a remote routing table on the access server so that the communication box and the access server use the same link at the same time.

An electronic device may include: a first subscriber identity module (SIM); a second SIM; a flexible display having at least a portion which can be folded or unfolded, and including an area corresponding to the first SIM and an area corresponding to the second SIM; a communication circuit; a memory; and a processor operatively coupled, directly or indirectly, to the first SIM, the second SIM, the flexible display, the communication circuit, and the memory. The processor(s) may be configured to: receive, through the communication circuit, a notification related to the first SIM from the outside; provide the notification related to the first SIM to a designated area on the basis of a state of the flexible display when at least a portion of the area corresponding to the first SIM in the flexible display is in a folded state; and display an execution screen of an application corresponding to the notification related to the first SIM on the flexible display when the area corresponding to the first SIM is changed to an unfolded state while the notification related to the first SIM is provided.
