An electronic device is provided. The electronic device includes a wireless communication circuit, a memory for storing an EARFCN list, and a processor configured to identify whether the electronic device is in a designated mode, when the electronic device is in the designated mode, perform a scan sequentially on at least some channels from among a plurality of channels included in the EARFCN list, when a first channel satisfying a first condition is identified as a result of the scan, identify whether the first channel corresponds to a second condition by decoding a system information block (SIB) or a master information block (MIB) received through the first channel, when the first channel satisfies the second condition, select a cellular network regarding the first channel, and when the first channel does not satisfy the second condition, stop the scan and perform D2D communication during a designated time.

Electronic device for supporting device-to-device communication and method therefor

A user equipment (UE) is provided. The UE includes a first subscriber identity module (SIM) configured to correspond to a first cellular network, a second SIM configured to correspond to a second cellular network, a wireless communication circuit, and a processor configured to determine a SIM to be used for Internet data communication among the first SIM and the second SIM as the first SIM, perform a connection process for Internet data communication and internet protocol (IP) multimedia subsystem (IMS) communication for a voice call with the first cellular network using first identification information about the first SIM, perform a connection process for the IMS communication with the second cellular network using second identification information about the second SIM, configure a parameter for the UE to support a narrow bandwidth for the second cellular network in UE capability information and transmit the UE capability information to the second cellular network.
