Now we know—it's called Xfinity Mobile, which is running on the Verizon Network. That means if you have good Verizon coverage where you live (most people do), you'll have good Xfinity Mobile coverage. Xfinity Mobile will have iPhones and several unnamed Android devices from Samsung and LG. The phone has to include services that force that connection, so they have to be modified for Xfinity Mobile. Xfinity Mobile might be a good deal for a subset of people who already subscribe to all of Comcast's services.
