I am selling this item due to a model change. I purchased it new. It has no noticeable scratches and is in good condition, and it works properly. *The SIM card has been removed. Regarding usage: You can comfortably watch videos on YouTube, etc., without any interruptions. Online games may experience lag depending on the time of day, and web conferences may also experience lag. It may not be suitable for online games or web conferences, but it is a perfect product for those who only watch videos or browse the web. Also, it does not require line installation, so it is recommended for those who move frequently. - Supported networks 4G LTE WiMAX2+ - SIM-free - Weight Approximately 436g - Included items AC adapter (other manufacturer) - External dimensions (mm) Approximately 93 (W) x 178 (H) x 93 (D) mm - UIM card version au Nano IC Card 04 LE U - OS Windows®︎10, 8.1 Mac OS X v10.15, v10.14, v10.13, v10.12, v10.11, v10.10, v10.9 - Wired LAN standards 10BASE-T, 100BASE-TX, 1000BASE-T (Gigabit compatible) / 2 ports - Wireless LAN standards IEEE802.11ac/11n/11a (5GHz band) IEEE802.11n/11g/11b (2.4GHz band) - Maximum simultaneous connections Approximately 40 devices (2.4GHz: 20 devices, 5GHz: 20 devices)
