I think the 3G service is still valid and a great deal, just can't recommend a seller. Two of the three hotspots I bought are still working but only because having one shut down caused me to call in on the other two early.
I agree about 4gas customer service, simply a pleasure to do business with. Their $15 a month 5 gig hotspot with Binge on and music freedom gets wonderful speeds when the signal is good. I used just under 30 gigs last month via the Binge on and Music freedom and the unlimited throttled data once you do hit your limit is usable for anything but video.
