Who saves money by switching to AT&T's shared data plan? The numbers don't remotely add up for me: Before: $60 700 family minutes $30 unlimited family messaging $50 my data, 5 GB with mobile hotspot $25 my wife's grandfathered data, 2GB $30 son #1's iPhone data, 3 GB $10 x 3 = $30, three family handsets, one being a dumbphone $225. 700 family minutes, $10 GB total data, Three iPhones and a dumbphone. Or... $120, 10GB Mobile Share $30 x 3 = $90, three iPhones $30, dumbphone $240. What do I get for that extra $15? Unlimited family minutes (we don't come close to using 700) Facetime over LTE Mobile Hotspot for everyone The ability to add an iPad to the account for $10 Not worth it for us. I would have liked to save some money by sharing data, not pay more. Is there a scenario where folks save money, or isn't that the angle for AT&T?
