The LTE-compatible Wi-Fi router WN-CS300FR provides a stable connection. I used it for about 9 months with a micro SIM card for Rakuten fixed-line service, but I am selling it due to a change in service. It comes with the box, adapter, and instruction manual. The settings password is on a sticker on the back of the unit. It is a beautiful item with no dirt or scratches, but since this is subjective, I marked it as "no dirt." - Model Name: WN-CS300FR - Type: Wi-Fi Router - Communication Method: LTE Thank you for looking.
