Overview

You can also change the billing mode later if it no longer meets your needs. If you change the billing mode of a public NAT gateway from yearly/monthly to pay-per-use, the pay-per-use billing mode takes effect only after the yearly/monthly billing mode expires. If you change the billing mode of a public NAT gateway from pay-per-use to yearly/monthly, the new billing mode will take effect immediately. Private NAT gateway supports only the pay-per-use billing mode (hourly) and the billing mode cannot be changed.
