Used for one month. Selling because I stopped using the e-sim. It worked normally with both SIM and e-SIM. The battery was used once during an update. The dedicated USB cable is unused. I think it's in good condition, but it's been used, so there may be small scratches. Please refrain from purchasing if you are concerned about this. * Brand: FUJISOFT * Model Name: +F FS045W * Frequency Band Class: Dual Band * Wireless Communication Standard: 802.11a, 802.11ac, 802.11b, 802.11g, 802.11n * This is a SIM-free 4G mobile Wi-Fi router that supports eSIM.
