I just noticed this thread last night.
Tested, pay for 600/20 @ 88.94/month - got an average of 370/19 over 6 tests (2 different phones and my WIFI laptop)
Got to poking around on the website today, there is a plan that's 100/5 (my AT&T hotspot on phone 1 provides around 175/15 so I figured why pay for 600/20 when I do not need it, and if it's ever too slow I can hotspot.....) which will run my smart thermostat and let me watch Netflix just fine. Going to save 50$/month. Thanks BITOG! My other phone is a Visible prepaid on LTE and I stream just fine with it 24/7, usually at ~50 mbps so why pay for something I don't use? I also live approximately 3-400 yards from the network centralizer so I doubt I'll really see unusable (under 25mbps) even on the base tier.
No idea what we pay for here at work but we have a LOT of stuff running on wifi - at least 40 laptops (wifi) 50-60 pc's connected by cable and maybe 40 other wifi devices (tablets, RF Scanners etc...). My phones see 300/300 and sometimes as high as 500 later at night
