Sometimes 100 minutes is enough for the month and sometimes it isn't. I would love if my unused minutes could carry over to the next month (maybe have a maximum number of minutes to be carried over/saved up). Also, I would appreciate a notification sent to my phone when I have used all of my minutes such as "Whoa there! You've used all of your anytime minutes! You will be charged $X.XX for any additional minutes". It would ease the shock of seeing an additional $30 spent in minutes!
