It has fluctuated over time, but has almost always been over the minimum limits (25/3) IMO. It is also vastly more reliable than our only WISP option in the area.
What I have seen is that the cell will start to fill up, speeds slow down a little (still better than our WISP and other Satellite providers), then the cell closes. More satellites launch, speeds go up, and the cell opens again. It's my experience, so take it with a grain of salt. I've had it since the original beta / before 100% coverage.
Most of the complaints I see are from people with existing cable options. It is not as good as cable/fiber, but a complete game changer for those of us who have had flakey connections.
