I'm pretty inconsistent with my use of data. There are some months that I use it up quickly and have to conserve as the billing period runs out. There are others (like this one) where I use only a portion. It would be great if Verizon would push any unused data for each month into a "safeguard" account to cover me when I potentially go over. Is there anything like this in existence? If so, how do I get it? If not, how can I get Verizon to put something like this together?
