Hi. I currently have the iPhone $69.99/mo plan with AT&T Wireless. My wife, who is with Sprint now, is considering switching over to AT&T as well, but she does not plan on buying an iPhone. In fact, all she wants is the basic plan (phone calls) + 200 texts (i.e. no data). That being the case, can I switch to their FamilyTalk plan and simply add her as the second line? I am going to visit an AT&T store tomorrow to ask, but it would be great if someone can give me some heads-up on it. TIA!
