IWant unlock my iphone carier

You must ask your current carrier to remove their sim lock.

Whatever carrier locked the phone is the only carrier that can release the lock. Unfortunately, if what your signature says is true, you are out of luck. If you are really talking about an iPhone 6 and are really locked to a Japanese carrier, you will not be able to get it unlocked. The Japanese government requires SIM lock release only for devices introduced to the market after a certain date. For iPhones, the oldest phone that can be unlocked in Japan is the iPhone 6s.
