My wife works remotely for her job and sits at different places. Her VPN won't work on a lot of the free wifi. The phone works as a hotspot, but is slow. I have read that a dedicated hotspot is better than off your phone. Who is the best hot spot for south College Station mainly. I have always had better luck with AT&T than verizon, but it looks like T-mobile has decent coverage also on the south end and is cheaper than AT&T. Don't want to go cheaper if it doesn't work. Any input on what people prefer?
