Initial Charge:
Your first charge will occur at the end of your trial period. The trial period lasts for 7 days from the day you sign up or until you have used all your free trial minutes, whichever comes first.
Monthly Billing Cycle:
After your initial charge, you will be automatically billed on a monthly basis. Your billing date will be the same day of the month as your first charge.
Example:
If you transition to a paid plan on August 8th, your next payment will be on September 8th.
