How included usage works: your included replies and voice minutes are added to your wallet as credit at the start of every billing month, priced at $0.01 per reply and $0.10 per voice minute. On the entry tier that is $17 of monthly credit (500 replies at $0.01 plus 120 minutes at $0.10). Anything beyond your included usage is deducted from your wallet at the same rates.
