Have had the FMCA Sprint/TMobile hotspot plan for only a month. Bought this because of the 'unlimited, unthrottled' aspect. Figures it wouldn't last long as our luck is not that great. We're in SW Phoenix now. Experienced throttling (they can call it whatever they want, but it's still throttling) a couple of times after we hit 50Gb. Seemed to last at least an hour and mostly at night. Once we got discouraged with the crappy streaming, we switched to our phones hotspots. Next day, it seemed normal. Our plan renews on the 20th, so all is good now. But since we're not moving and we won't probably change towers, I'm not expecting this process to improve back to the old process.
Have tried resetting the router (LinkZone 2) and that seemed to work the first few times......but since the button is on the inside, it's not handy. We turn the hotspot off when not in use now.
