Bill there are several ways to do this. I'm using a Pepwave Max BR1 cell router that will also pick up wifi with an additional $100 license. One big advantage is that I have an additional firewall when connected to an open wifi. My Pepwave has 2 sim slots for failover if needed + lan and wan ports. I'm using a MIMO antenna on the roof and get 2-3 bars where our phones won't see any signal. Not using a booster. I've never been throttled even when using over 300Gb/month from streaming. It even worked well in Alaska but not in Canada on our ATT plan.
At the lot we just bought in Colorado I can get a 3G ATT signal which is ok for email and light surfing. I also have DSL with a router in the shed and have the Pepwave connected to it and am getting 10Mb down so it's enough to stream.
The issue is finding a cell plan with unthrottled unlimited service. ATT has an iPad plan that I think is still available, Verizon has their Visible plan which I've heard is unlimited. Both of these can possibly be used in a cell router like above. There are also resellers on ebay and others with grandfathered plans.
