I can't find a tool that shows my total bandwidth/data useage per month for FIOS. I've asked Professor Google and searched the forums, but only found one answer from someone who said that there's no need for such a tool. Obviously that's NOT the case since there are multiple users with the same question on the VZ forums and many other internet forums. Thanks in advance.
Verzon doesn't have hard data caps.
They have terms that say if you are an excessive user (usually found to be in the terrabytes of usage), you may be cut off from service.
But that isn't an issue for most home users.
