I was paying $140ish a month with Verizon (included hot spot, which was an extra $30 a month), now I pay $60.
My family was grandfathered in to the unlimited unthrottled Verizon plan, and while it still existed I was using a "dumb phone" without a data plan. After the unlimited plan was no longer on the market, I got a smartphone, and that somehow kicked the other 7 lines on my family plan off the unlimited plan that they were grandfathered into.
In short, hey, can I pay you to use one of those spare lines?
I presume there are some legal reason why they haven't done so yet?
