Our services are prepaid, so you are billed on the 1st of each month for the duration of that month.
E.g. Your April invoice is issued on the April 1st, and covers until April 30th. Your May invoice is issued on May 1st and covers until May 31st, and so on
When you sign up, your bill is prorated
E.g. If your services are activated on March 20th, you are only billed for the period March 20th - March 31st. Your next bill will be April 1st, the bill after that on May 1st, and so on.
