I double checked their plans and here is my conclusion:
if you opt for the cheapest family plan, you will not be able toI add data and smartphones to it. bummer
if you go with a plan that has the option to add data, you will be looking at around 180+taxes and surcharges. You get unlimited minutes to ANY domestic carrier and 1500 minutes for calling Sprint numbers. (to me this just does't seem logical)
Im paying around 150 now for unlimited data, text and unlimited att to att minutes. Only have around 550 or so (500?) minutes / month but since almost everyone we call uses att, we have loads of rollover minutes...I
wall of text but I hope this helps
