USA Today is making that up. There's an unlimited calling, unlimited texting, 300 MB data plan but
- 1) it's only for basic phones (not smartphones)
- 2) it costs $70 per month (not $80)
VZW's PDF (http://solutions.vzwshop.com/shareeverything/pdf/verizon_share_everything_plan_details.pdf) excludes smartphones from the "Share Everything Plans for Basic Phones" and "Data-Only Plans," therefore the minimum charge per month is $90 -- $40 for the device, $50 for 1 GB data. I'd argue the minimum is $100, since (if you keep reading) it's worded like a family plan with a two-device minimum, and the cheapest 2nd device is a tablet @ $10.
What isn't clear is if there will be single-line pricing, though the wording ("Select one smartphone and up to nine more devices", emphasis mine) implies that it'll exist. Most of the multi-line scenarios I can think of, however, are running $10-$30/mo higher with SE, with the biggest hit to basic phone non-texting customers. In my case, it's $110 now (2 basic phones, 1 smartphone w/unlimited data, no texting) vs. $150+ on SE (1 smartphone, 2 basic phones, 1 GB data, which I would definitely use in a month) so that's a ~33% increase.
