Method and apparatus for searching networks

An electronic device comprising:

• a wireless communication circuit;
• a memory;
• and
• a processor connected with the wireless communication circuit and the memory, the processor being configured to:
• perform a first network scan to search at least one of a plurality of accessed frequency bands stored in the memory as accessed network information,
• perform a second network scan to sequentially search a plurality of predetermined frequency bands for country information from a mobile country code (MCC), in response to the first network scan failing,
• perform a third network scan to search a plurality of frequency bands related to the country information, in response to the country information being identified based on a result of the second network scan, and
• perform a fourth network to scan all frequency bands supported by the wireless communication circuit, in response to the country information not being identified by the second network scan,
• wherein the plurality of predetermined frequency bands are arranged according to a size of global coverage for each of the plurality of predetermined frequency bands.
