Should Sony z3 docomo Japanese Edition Add Area Code? And docomo's cell phone, okay? Is the international version of z3 a Hong Kong version?

Japanese version Z3 can only be used if it is unlocked, without adding area code. Docomo is a Japanese operator. Docomo phones are all from custom machine, and you can use China's sim card only after unlocking them. There will be no quality problems if the machine is not refurbished. International edition, generally referring to Hong Kong edition, refers to other non-custom machine editions except Bank of China and Japanese edition.
