Figuring out if AT it’s $85, to start, including DirecTV.
For two people:
— The unlimited plan costs at least $150.
— A 5 GB phone plan costs $100; 15 GB costs $130. Adding TV costs at least $10 a month more to start.
Figuring out family finances is more complicated. A family of four would save money with the unlimited plan if they would have opted for a plan with 20 GB, but spend more if they just wanted to share 15 GB.
