I live in the mountains and the internet (Comcast Cable) goes out frequently during the winter months. I want to set up a backup internet using cell phone. Is there a phone and data plan that I can buy that will allow me to set up a WiFi network that I connect two laptops and trade. I know there's a little gizmo you can buy that you can connect one laptop to the internet but I need to run two laptops. I'm not a cell phone person at all and just have a basic phone with AT&T. I don't think I'm in an area with 4G coverage if that matters. I think I saw a commercial for this feature but I'm not sure. Any insight would be appreciated.
