Overview

Enterprise Router supports only pay-per-use billing. It is a postpaid billing mode. You pay as you go and just pay for what you use. You are billed for the duration that each attachment is used and the traffic that flows from each attachment to an enterprise router. The duration is calculated by the second but billed every hour. This allows you to adjust resource usage easily. You neither need to prepare for resources in advance, nor end up with excessive or insufficient preset resources. For details, see Enterprise Router Pricing.
