Billing Details

Billing Rule

Billing Period


Billing item: traffic

Payment: post payment

Billing method: You are billed based on traffic tiers. The traffic usage is accumulated in each calendar month.

Conversion rule: 1 GB = 1024 MB

You are billed on an hourly basis. The usage in an hour is usually billed four hours later.

Example: Fees generated from 18:00 to 19:00 are deducted at about 23:30 (subject to the system).

You are billed by the traffic used per hour.

  • Bandwidth usage = Traffic used per day (GB)/(Peak bandwidth (Mbit/s) x 10.54). The number 10.54 indicates that a bandwidth of 1 Mbit/s at 100% usage generates a daily traffic of approximately 10.54 GB, that is, 1 Mbit/s x 100% ÷ 8 bits per byte x 60 seconds x 60 minutes x 24 hours ÷ 1024 MB per GB = 10.54 GB
  • Fees for bills generated from 23:00 to 00:00 will be deducted at about 15:20 on the following day.


Traffic-based billing has .

Example: The traffic consumed by company A from January 1 to January 10 is 10,000 GB (about 9.77 TB), and the traffic consumed from 00:00 to 01:00 on January 11 is 300 GB. By 01:00:00 on January 11, the total consumed traffic is 10,300 GB (about 10.06 TB). Of the 300 GB used from 00:00 to 01:00 on January 10, 240 GB is billed at the 0 TB to 10 TB tier with a unit price of M1/GB. The remaining 60 GB is billed at the 10 TB to 50 TB tier with a unit price of M2/GB. In short, for the period from 00:00 to 01:00 on January 11, you would be billed 240 GB x M1/GB + 60 GB x M2/GB.

Bill Run Time

The system generates a bill for fee deduction 4 hours after a billing cycle ends. The bill for a month will be usually generated on the third day of the next month. The actual bill generation time may vary slightly from month to month.
