non-Verizon pay as you go Hotspot?

I will check out FreedomPop. It looks like they charge you $40 for a device then so much for certain amounts of data. I guess I should have been more specific: What I'd like to find is a non-verizon phone and hotspot. We need a phone that works in Leakey Tx (near Garner SP) whre verizon has zero service, and I'd like it to also be able to work as a hot spot so my DW can connect her tablet to the internet in and around Houston. Kind of killing two birds with one stone. if yiou kniw what I mean. Thx Dave
