This is an Aterm mobile router, the NEC MR05LN, made in Japan. I was using it with a Rakuten Mobile SIM, but I'm selling it because I moved to a property with internet. The battery had expanded, so I disposed of it and it is not included. Please purchase a separate battery. - Brand: Aterm - Model: NEC - Type: Mobile Router Please purchase only if you understand that this is a used item.
