Home Router Mobile Router FS040W Home Kit with Charging Dock No noticeable scratches or stains, operation confirmed. The following is an explanation from the internet: This is a set model of the FS040W main unit and the optional FS040W dedicated home kit. You can use it as a mobile router when you are outside and as a home router at home. The FS040W is equipped with a large-capacity 3,060mAh battery, allowing for up to 20 hours of continuous communication when you are out and about. The FS040W is SIM-lock free, so it supports many communication companies, including the four major domestic carriers. You can choose the communication company that suits you and enjoy the internet at a great value. Please check the manufacturer's product website (+F (Plus F) website) for specific SIMs that have been confirmed to work. APN can be set automatically. You can access it without a password, so there is no need for troublesome settings. (Automatic settings may not be possible depending on the SIM you are using) When you suddenly need power, such as when your smartphone battery runs out while you are out, you can supply power from the FS040W to other devices in "battery power supply mode".
