Yes, though the $25/month *might* include a $10 bundle discount, I'm not sure.

Edit: The way it works is that, when you start the service, they ship you a white cube thing that contains a cellular modem + wifi router. You just plug that into a wall outlet and it connects to the internet and creates a wifi network for you.

There's also an ethernet output on it, if you want to use your own wifi router instead.
