Abstract: An electronic device and an electronic device operating method are provided. The electronic device includes a digitally compensated crystal oscillator (DCXO) generating a reference clock for generating a signal having a reference frequency, a transceiver for supporting auto frequency control (AFC) performed so that the signal has a frequency of designated range, memory storing one or more computer programs; and one or more processors communicatively coupled to the DCXO, the transceiver, and the memory, wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to control the transceiver to search for a base station included in a network to which the electronic device is to be connected by changing the frequency of the signal within the designated range, enter, based on a failure of the search for the base station, a mode for changing the designated range, change the size of the designated range, and search for the base station again based on a signal having a frequency of the changed range.
