My INSEEGO m2000 will connect to Sprints 5G where I am at on the FMCA plan. But the 5G is about the same if not slower than the 4G where I am. If I take my mifi about 2 miles down the road it will get a stronger 5G signal and will go Much faster. I know the plan says 4G but not sure why I can use the Sprints 5G..
