We have multiple devices on our family plan and it's not uncommon for 600GB+ to be used in a month. I often travel around the country on work and use 2 jetpacks for 20GB(10 each) of 4G LTE hotspot speeds for my laptop.
Now my concern is at the beginning of the month speeds aren't too terrible, but when one is getting close to or past 10GB it gets very very slow (10-70kbps) I will power it off and turn on my 2nd jetpack with 0GB used and speeds will not increase at all.
This leads me to believe that even though I have been blatantly told by numerous people that it doesn't matter if the family plan has 1000GB of data used, each device will have full 4G LTE hotspot speeds until 10GB... It's actually being throttled based on the family data used.
Which is why the first device will slow down before 10GB have even been used and the 2nd device that hasn't been used at all will provide no better speeds.
Can I get clarification on this?
PS- I have already been in contact with support troubleshooting both devices with no answers as to why the speeds are as they are. I can't think of any other conclusion.
