Anyone have experience with this service? It's marketed, I gather, as an alternative to satellite internet and it's only available in certain areas. Internet service is provided via hardware on a cell tower rather than through a satellite. Download speeds are supposedly 10-25 Mbps, low to high, and the monthly data cap is 250 GB. Compared to satellite, this seems like a superior service for half the price. I'd appreciate to hear from anyone who has some experience with the AT&T option.
