Method of accessing network based on access technology and electronic device therefor

An electronic device comprising:

• a first wireless communication circuit configured to provide wireless communication based on a first radio access technology (RAT) associated with a long term evolution (LTE);
• a second wireless communication circuit configured to provide wireless communication based on a second RAT associated with a new radio (NR);
• a subscriber identification module;
• a processor connected with the first wireless communication circuit, the second wireless communication circuit, and the subscriber identification module;
• and
• a memory connected with the processor, wherein the memory stores one or more instructions that, when executed by the processor, cause the electronic device to:
• obtain access technology identifier (ATI) information associated with one public land mobile network (PLMN) from the subscriber identification module, and
• based on the ATI information indicating a next generation radio access network (NG-RAN), perform frequency scanning by using the first wireless communication circuit or the second wireless communication circuit based on an RAT priority.
