I found this ad on Craigslist from a store claiming it can do 2 years of unlimited for a $50 activation and sim card.
I asked why Google Voice is involved and he said it is programmed in the sim. He also mentioned it is a real voice and text. So not sure how this is done.
The information I googled for Global sat prepaid sim is here:

And his Craigslist ad is here:
https://lasvegas.craigslist.org/mob/6077406044.html
I'd be suspicious of anything with "mob" in the address:
True, one must be careful as some of them look legit.

If it sounds too good to be true.......
It might actually be true--people do win the PowerBall Jackpot.

As suggested by arrynrob it is almost certainly bogus.
Cell service is a commodity that resellers buy wholesale. If someone is "providing" it at a price that differs significantly from what established companies charge, then the "offer" it is not what it appears to be.
I thought it was bogus too but I called anyways because he was local and it intrigued me. I thought maybe he found a workaround.
