Invoices are generated on a monthly basis. If you select a Monthly Minute Plan you will receive your first invoice when you subscribe to the service. The charges reflect the Monthly Minute Plan charges you selected. Pay-as-You-Go customers and overage charges for Monthly Minute Plan customers are charged at the end of the billing cycle.
You will receive an email notification within the first few days of the next billing cycle advising you that an invoice is available on-line for you to view, pay, and/or print for your records.
