FMCA Tech Connect from Sprint/T-mobile (Sprint side) I observed no lmits when I had it. Now speeds varied from around 5 Mbps to over 100 depending on where i Was (only one spot hit 100) At the time Sprint and T-mobile had JUST announced the merger and towers were still one or the other... With the merger of towers now rumored to be complete. I don't know how that will affect the speed.
50/month and one time 50 setup... I was happy.
Only issue is occasionally I had to shut off. and turn back on (not restart) the device A few times I just did a restart. one time I had to power off then back on.
