This is a device I used with Fuji Wi-Fi! It's a pocket Wi-Fi, the H01. It has a 2500mAh battery. The body only. Please insert your own SIM card to use. The product condition is relatively good, I think. I was using it as a substitute for a fixed-line connection, so it's a used item. The battery lasts for about a day. Up to 10 devices can be connected simultaneously. - Model Name: H01 - Version: K1_TSV3.1.005.001.240116 - IMEI: 864300040263007 - Data Terminal Type: 4G Wireless Data Terminal - Capacity: 2500mAh Thank you for looking.
