I have added a $5 add on to my monthly bill, however, I notice that I am being charged $7+. Does anyone know why?
When I try to check my usage on my current bill, it is never available at this time. If it is not available, how do I get charged for usage.
Sounds like proration. You get charged from the days you activated the add-on until your cycle date and then the full month like normal, so it's usually higher on the first bill. Same thing happens if you change plans.
