Dan just got a new iPhone and he and his son has shared data. How does that affect when he uses his phone as a personal hotspot? Leo says that when he uses a personal hotspot, it brings no more to the party, he's just paying more for the priviledge of hotspotting. Dan can use a free service like FreedomPop, but it's for a very limited amount of data. Then he'd start paying. Wi-Fi hotspots, though, will cost him nothing. So if he's at a Starbucks, he can connect to that and it won't count against his data at all. But he can just watch his data and only pay when he goes past the 10GB threshold. It's just easier that way.
