You have a few options. One is to contact your provider via phone and ask them for a outline of your current packages, fees, usages, etc. The other option is that most providers allow you to login to your account online to view your current subscription and usage rates, this is very useful as you can see your usages typically in real time. However, one downside to logging in online is that a lot of providers don't update the billing cycle portion online right away so you may have different prices in your online bill pay versus over the phone with a representative.
