Abstract: An electronic device may include a first subscriber identity module (SIM), a second SIM, a communication circuit, a memory, and a processor. According to an embodiment, the memory may store instructions that when executed, cause the processor to set the first SIM to a SIM associated with a data service, and the second SIM to a SIM irrelevant to the data service to determine first capability information associated with a function supported by the electronic device in connection with the first SIM, and second capability information associated with a function supported by the electronic device in connection with the second SIM. The instructions may also cause the processor to transmit the first and second capability information to the network, and to receive allocation of a resource for wireless communication corresponding to each of the first and second SIM from the network, based on the first and the second capability information.

Abstract: According to an embodiment, an electronic device may comprise memory and at least one processor, comprising processing circuitry. The memory may store at least one instruction that, when executed by at least one processor, individually and/or collectively, causes the electronic device to: perform a call service based on a first network communication corresponding to a first subscriber identification module (SIM) in a state in which a first portion of RF resources of the electronic device is allocated for the first network communication corresponding to the first SIM, and a second portion, at least partially different from the first portion, of the RF resources is allocated for a second network communication corresponding to a second SIM different from the first SIM; identify a service failure in the second network communication corresponding to the second SIM while performing the call service based on the first network communication based on the first SIM; based on the service failure, perform a scan for the second network communication corresponding to the second SIM one or more times; and perform at least one operation for restricting the scan for the second network communication based on a cell for the second network communication not being identified as a result of the scan one or more times.
