I have 2 phones on my acct. Mine and my daughters. She has an iphone, with data plan. i have a non smartphone. My question is, if we switch phones, we change sim cards, how do I go about switching that data plan to my sim card/number.
 I dont want to have no data plan, but I dont want att to auto add a 2nd plan either.
 can i do the switch from my acct add features? or shoudl I call a rep (i hate doing that, too slow)
