What happens when I cancel?

Your plan runs to the end of the paid period, then the account returns to Free with your prepaid balance untouched.

Your plan stays active until the end of the period you’ve already paid for, then the account returns to Free pay-as-you-go. You can resume anytime before then and nothing changes. Your prepaid balance is untouched. (An operator-provisioned Enterprise/comped plan ends immediately instead, with no scheduled end date.)
