I know we have shock free for data, so what's an easy way to check on your airtime usage during the month to see if you are reaching your limit: the usage page in selfserve doesn't seem to distinguish between calls made during unlimited calling periods and calls made during other hours (ie the ones where you could eventually go over your limit). To figure it out you'd have to sit and do a bunch of addition (who has the time?? = not an option). Is it a passive way for the company to profit? Am I missing an easier way? Thanks!
