Abstract: An electronic device may include a subscriber identification module, a wireless communication circuit, and a processor, wherein the processor identifies information on a country where the electronic device is located, when the country where the electronic device is located is changed on the basis of the country where the electronic device is located, generates a PLMN list corresponding to the country where the electronic device is located, performs network search based on the PLMN list via the wireless communication circuit and when a cell of a PLMN included in the PLMN list is detected through the network search, performs registration in the detected cell via the wireless communication circuit.

Abstract: A data storage device includes one or more nonvolatile memory devices each including a plurality of unit storage spaces; and an address recommending circuit configured to recommend a unit storage space among the plurality of unit storage spaces to process a write request, wherein the address recommending circuit applies feature data to a neural network to recommend the unit storage space, and wherein the feature data is generated based on request information for the write request, a target address corresponding to the write request, an address of data stored in the plurality of unit storage spaces.
