Hi everyone, Recently I purchased a new AT&T account and 2 iphones , so far I am happy with the iphones. I have 3 lines in my FamilyTalk plan. In my Original order, I requested 2 iphones along with data plan (I had to). Anyways, my wife mostly uses wifi, she has a pretty good wifi accessibility, that's why she never tried 3G till yesterday. Once we tried it we got an error that shows "Cannot activate cellular data network". I logged into my account to see what's going on, even though her line and my line show we have iphone, only my account does have $30 data plan but not hers. She is OK with not having 3G plan, I am also OK with that for being pay less , but will AT&T charge me for the data plan in the future for the not paid months?? Should I contact them to get this fixed?
