To keep costs down, Speak Out does not offer online account management, or access to billing. It's easy to find how much time you have used. You can activate the call timer function on your phone. Also, all you have to do is call *777 (it's a free call) and it will tell you how much is left on your account.
When I went up north, I made a call, and knew how long the call was (due to the call timer on my phone.) I also called the *777 number before and after the call to make sure I was being deducted the right amount.
