It stopped working after being water damaged. This is a completely junk item. However, it sometimes starts up if you plug in the power cable and hold down the power button. When checking the battery status, it displays "reading failed." See the image. It stops starting up when restarted. Please purchase only if you understand this. The carrier appears to be SoftBank, but it has only been used in a WiFi environment, so it's unconfirmed. SIM lock is not unlocked.
