I used this with a Rakuten Mobile line for two years. In the latter half, it often got disconnected (it worked after logging in again). I haven't been able to determine if the issue was with the device or the SIM, so I'm selling it as junk. There are traces of sticker removal on the part shown in the third photo, but it's barely noticeable. Initialized. No original box. I will protect it with bubble wrap and ship it in a Yu-Packet Plus box.
