I really like the per device usage that shows throughout the current month (see attached). What I would like to see is the same list selectable per month for historical usage. Even better if this is on the phone app. Otherwise I have to try to log on the day before the billing period and copy down the numbers. If I don't then I'm stuck going through all the usage history and adding up the minutes for a particular person.
I need this because some of the people on the bill pay me for their portion of the service.
What would be even better is if you could calculate the portion of the bill that each device incurred. For instance if we were in a $25 dollar minutes bracket, divide that by the total minutes used to get cost per minute, then multiply by the minutes for that user. Do that for minutes, texts, and data, add on the $6 per device fee, add on a portion of the tax and your done. You could even do this in real time throughout the month similar to what is done now, but to me the historical usage & cost is most important.
