I'm trying to reach the department that deals with cell phones but it is not an option on the recorded voice. How can I get information from cell phones

You need to call COSTCO, request customer service. The customer service center will assist you with questions or transfer you directly to the representative handling cell phones. Please note that the Costco business center does not have a cell phone center.

Electronics should be an option.

They don't do cell phones here.

Maybe press 0 for the operator.

Press an option for admin/management, then ask to transfer or give you a direct call number. Good luck.
