I just signed up and realize data usage starts over each month, but is that the first of the calendar month or is it based on the day the service starts?
It is my understanding that billing dates are about every 3 days. I have often completed installations and the customer's billing was a day or 2 later. That means they could use all their data in those 2 or 3 days and it would reset on their billing date. This has caused confusion and some irate customers when they get a first bill for a month plus 2 or 3 days without any explanation.
