... so right after I added topups on my accounts


So disabling auto top-up will cost $5, but at least you can use all the allotments now.

Good Article

Didn't disabling auto-top-up on GSM SIMs only limit the last 20mb, rather than the 100mb on the Sprint devices?

I wonder if this means Sprint has changed it's data reporting, since the possibility of unintended overages has been 'a thing' on Sprint MVNOs-- or whether FreedomPop has just decided to absorb that risk.

Sounds like a policy change to just absorb the risk due to customer complaints.
