This is an au Speed Wi-Fi HOME L02 Wi-Fi router. I purchased this unused, second-hand, and used it a bit with WiMAX 2+. However, I ended up switching to a cradle-connected mobile router, so I haven't used this one much, and it's in very clean condition. I have confirmed that it works with au-compatible low-cost SIMs before listing it. I forgot to reset it, so please reset it before using it. Due to the size, I will ship it in a clear plastic bag inside the product box. If you prefer it shipped in a separate cardboard box, it will increase the size, so it will be an additional 200 yen. Thank you.
