I currently have a Family Plan with AT&T with 3 iphones (unlimited data) and 2 non-smart phones. I was excited to hear about AT&T letting customers with unlimited data plans to keep them for the new iphone. However, my question is that the other 2 non-smart phones on my plan are about to become iphone 5s. Planning on ordering 5 of the new phones tonight. But how is that going to effect my plan? Will I be able to keep 3 of the iphones on the unlimited plan and then have the 2 new phones on one of their other data plans? Has anyone had experience doing something similar?
