Hey,
I live out in the middle of rural nowhere in the NE us. I used a Mofi 4g router and am able to get 80mbit down 60mbit up, I pay 35$/mo using AT&T. You can use external antennas and its great but the default upgraded paddle style ones are great for me, even going through a wall. AT&T has a hidden unlimited wifi plan if you use an ‘ipad’ sim card, which means spoofing an IMEI when u sign up. I get better latency than my copper 6mbit/0.3mbit connection for gaming.
