Again, wish I could paste the screen shot taken. What I'm seeing is AT&T's comparison of data plans with what I already have and what they would recommend. Under "View or Change Rate Plan", I go to "Choose a New Rate Plan" and click on "View All Plans". This is where the pop-up chart is that lists 1GB for $86.25. I have two cell phones under a Mobile Share Plan.
Lost in all of this was my point of the rate plan doubling, which was answered by one of the first replies. Thanks.
