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.
I mean for most people this should work fine but it seems they have no initial cap. So it is pretty likely it will take days or even weeks for many people to fully transition (or years when you are a data hoarder). Also I think a weekly or monthly limit would be better as it is pretty likely IMO that will occasionally need more than 50GB even as a rather casual user.
