Thank you Leiko27 for your help. The information you provided is absolutely correct. By following your instructions grimouire will be able to view the call usage details and see the calls placed and received.
I just wanted to make sure that when you sign into your My Verizon account to view the call usage details that you are signing in as the account owner. If you do not sign in as the account owner you will not be able to view the call details. You will know when you have signed in as the account owner because you will be able to see all the lines on the account.
I hope this information has been helpful.
