I was using this with a Japan Communications (Docomo line) SIM card. The SIM lock has been unlocked. There are no problems with basic functions such as powering on, screen display, and touch operation. However, the screen is cracked due to a drop, and there are paint剥げ and stains, so the appearance is not good. Also, there is a sticker on the back that a family member directly applied, and it has not been removed. Please check the photos for the condition. Due to the above reasons, I am selling this as junk. Please purchase only if you understand the condition.
