This is an old iPhone, just the device itself. Version: 13.3.1 IMEI: KDDI ◯ Capacity: 64GB Internet access via Wi-Fi was confirmed to be working without issues. With its large capacity, it's perfect as a sub-device. Please understand that apps that don't support this version may not work. I played YouTube for about 3 hours, and there were no audio or video problems. Since I was using it as a sub-device, I haven't checked phone calls using a SIM card at all. Please understand that there is no warranty. In the past, when I sold a smartphone, there was a cancellation request because of screen burn that wasn't visible in the photos. The issue was resolved without problems with the help of Mercari's administration, but this is a used item, not a new one. Please consider that there may be screen burn, scratches, etc., that are difficult to see, and purchase accordingly. Please understand that I cannot provide any support for any defects. Please read the comments and purchase, understanding that this is a used item and returns and refunds are not accepted. Also suitable for collections.
