The iOS version is 12.4, so basic operations are smooth. Jailbreaking is also easy. I have been using it in a jailbroken state. Also, since I've had a glass film on it since I bought it, the screen is in good condition, I think. The carrier is au. The battery condition is not good, as it's been over a decade. The rear camera does not work. The rear LED light does not light up. Due to the above defects, this is being sold as junk. It will be given to you after being initialized.
