Abstract: An electronic device and operation method are provided that include a communication circuit, a memory to store mapping data in which identification information of a cellular communication network and information indicating whether the cellular communication network supports a standalone (SA) mode of a first cellular communication supported thereby are mapped, and a communication processor to, while searching for a node through the first cellular communication and/or second cellular communication, receive system information broadcast by the node, determine, based on identification information of a cellular communication network included in the system information and the mapping data, whether a cellular communication network corresponding to the node supports the SA mode of the first cellular communication, and, when it is determined that the cellular communication network does not support the SA mode, stop searching for the node through the first cellular communication and search for the node through the second cellular communication.

Abstract: 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.

Abstract: A silicon layer etchant composition and associated methods, the composition including about 1 wt % to about 20 wt % of an alkylammonium hydroxide; about 1 wt % to about 30 wt % of an amine compound; about 0.01 wt % to about 0.2 wt % of a nonionic surfactant including both a hydrophobic group and a hydrophilic group; and water, all wt % being based on a total weight of the silicon layer etchant composition.
