Uses cellular data in places where you cant connect through fibre/DSL/regular modem's and provides an excellent and reliable signal to connect to. Uo to 300mb/second as per the blurb. I used mine on a farm and then connected a router to the ZTE Hotspot to transmit 50GB of data a month for the whole family to connect to through a plan with Rogers. I paid $180 for this hotspot new and its in excellent condition, so enjoy!.
