Picked up new iPad Pro’s for my wife and myself on AT&T Next. The sales guy offered us a $20 a month unlimited standalone data plan on our same 6 gig iPhone account without adjusting the iPhone 6 gig plan. He said that they just started offering this last week. It made sense for us because we have enough lines making the unlimited for all a bad option. Not sure if anyone knew about this or even cares, but wanted to pass it along.
