I use my Verizon phone as a hotspot for our laptops. They don't have 4g out here either and the options are the same as yours - stinko.
We don't use the computers all that much but I am pleased with the hotspot for what it is. We always have service and it is fairly quick.
When I tell people that we don't have Internet as it isn't available out here they look at me like I am from the moon. My how times have changed. I never would have dreamed that not having Internet service would put me back in the days of the WPA.
