I am currently on a grandfathered unlimited ATT with good speed performance. The cost for the single line is about the same between ATT & VZN unlimited. Two reasons I'd switch to VZN are tethering and a free trade-in to a 7Plus. I was just about the make the switch, and then I read an article that stated Verizon networks are going to be overloaded with all these new unlimited plans and their actual capacity cannot handle it and speeds will suffer. So, trying to decide if I should just hold tight on AT&T, because at least the speeds should remain as good or better than in the past. Any thoughts?
