I have OOKL and use it all the time on my phone or computer. I get a 5Guc signal at home, (T-mobile) and do not get consistent results , downloads range from 560 to 55, uploads on 5G seem to be much slower than if I connect to my wifi Comcast connection.
If I turn my phone hotspot on and connect my computer to the phone, a don't see the same speed as the phone shows, from phone to computer is not that fast.
