* Each line gets their own 5.
* You can change each of your 5 up to once a month anytime.
* People in your 5 can be on any network (cell or land-line)
* You get unlimited minutes to anyone in your 5
* You can add in-network mobile to mobile for $9.99 on the family plan ($6.99 I think on an individual plan)
hmm... I think that's all I know.
