Individual files can’t exceed 10GB, and you can only upload 50GB per day. Verizon will continue to offer its group unlimited plan for $19.99 per month for up to five people, who each get their own cloud storage account.

Pretty sure they already throttle the connection to 60 kB/s if they know you’re using it as a Hotspot.
I pay extra for the high speed Hotspot plan but I think it only gives me 10 or 20 GB then it throttles again.
