they give the idea that you'll benefit from carryover data every month if you are under your data allowance. This is FALSE.
No, this is TRUE. If you are under your data allowance for the month, the unused portion of your data allowance will roll over to the following month if you are on the new Verizon Plan.
Data which has ALREADY rolled over IS NOT part of your data allowance and therefore will not be rolled over again.
Your data allowance will be used before any rolled over data.
The fact remains if you have a data allowance of 10 GB and only use 8 GB, 2 GB WILL ROLL OVER to the following month.
