Hi all. I have been using Vodafone and I have recently bought an iPhone. I think I will change my service provider to at&t. I wanted to know some kind of reviews about at&t before I actually get the network. What kind of plans do they have? What are the calling rates in different sections of the call distances with respect to the countries and the network limitations? What about the signal quality and the things like MNP and app support? Please mention all this in your reply!
