This is just the NCP-HG100 home gateway unit. It was used with a Rakuten Mobile line. I am selling it due to a change in environment. It was working without any problems until recently and was operating stably. There were some initial issues with stable operation, and modifications have been made to stabilize it (USB 2.0 conversion, band locking). The AC adapter is not included as I was using my own. An adapter of around 12V 1A should work without any problems. Given the above, I would appreciate it if those who understand its use would consider purchasing it.
