If you are a new customer or if you are getting a new service hooked up, your bill will be prorated for the remainder of that month you signed up in, plus the fees for the following month’s services. This is due to communication services being billed one month in advance. For example if you sign up for a $20 service on the 15th of the month, your prorated portion for that month is $10, plus you will be paying $20 for the following month, which makes your total bill $30.
