Can someone explain to me how to do this? On the AT&T website when I try to add a line it says it's going to be way more then $10 a month. Please help!!! Thanks!!!
Yes, it's more than $10 a month because it's an iPhone. After you get it and at&t does the device swap, they'll remove data/put a dumbphone on the new line at which point it'll be $10/mo unless you're on the mobile share plan.
