I'm on T-Mobile's home internet. With just the modem chilling in my room, i can get about 200/20. I've bought an external antenna that I'm going to be hooking up to the modem and mounting on top of my house soon. Testing it in my front yard I was able to get 350/25. Latency/Jitter was also significantly better with that antenna. I'm not super rural, but we have literally no other internet options, are on septic/well water, and are about 10 minutes from the nearest store by car.
