Ok, I've looked on AT&T's website and am trying to understand the plan pricing. We're planning on two iPhones, ok, so $30 each monthly data plan, required, I understand that. Now how about the texting plans? If I pay $30 a month for an unlimited family plan, does that cover both phones? Or do I have to pay another $30/month for each phone for that? Is there any way to block texting on an iPhone? So we can't send or receive any texts? Thanks.
