If you are a comcast customer you can get a single line of unlimited data text and calls via Verizon network at half the cost. I don't get it. Verizon can supply a family of four with new phones and unlimited service for approximately 240 dollars per month but have to charge me 119 dollars per month for one line and a new phone to make up for that? Now Verizon is allowing Comcast to sell single line unlimited with new phone for approximately 70 dollars per month for use on their network. Please could someone offer an acceptable explanation of this business model.
