You can use public instances of the new version free of charge. This topic provides examples on how to calculate the fees for device connections and messages when you use IoT Platform public instances of the old version.

Note This topic is for reference only. To obtain actual fees, view your bills.

For more information about the billing methods of IoT Platform, see Billing overview.

Example 1

10,000 devices go online twice a day. The devices remain online for 2 hours at the first time and 6 hours at the second time. The devices are online for a total of 8 hours a day. During the online period, each device sends a message of up to 0.5 KB per minute. The current month has 30 days.

The fees for the current month are calculated based on the following billable items:

  • Messaging fee

    Number of messages: 60 × 8 × 30 × 10,000 = 144,000,000

    Messaging fee: 100 × 0.5 + 44 × 0.4 = USD 67.6. Note: For the first 100 million messages, you are charged USD 0.5 per million messages. For the excess 44 million messages, you are charged USD 0.4 per million messages.

  • Device connection duration fee

    Device connection duration: 60 × 8 × 30 × 10,000 = 144,000,000 minutes

    Device connection duration fee: 144 × 0.3 = USD 43.2. Note: You are charged USD 0.3 per million minutes.

  • Total monthly fee: 67.1 + 43.2 = USD 110.8

Example 2

10,000 devices go online twice a day. The devices remain online for 2 hours at the first time and 6 hours at the second time. The devices are online for a total of 8 hours a day. During the online period, each device sends a message of up to 0.5 KB per minute. Each device receives a message of 0.4 KB per minute. The current month has 30 days.

The fees for the current month are calculated based on the following billable items:

  • Messaging fee

    Number of messages sent in the current month: 60 × 8 × 30 × 10,000 = 144,000,000

    Number of messages received in the current month: 60 × 8 × 30 × 10,000 = 144,000,000

    Total number of messages: 144,000,000 + 144,000,000 = 288,000,000

    Messaging fee: 100 × 0.5 + 188 × 0.4 = USD 125.2. Note: For the first 100 million messages, you are charged USD 0.5 per million messages. For the excess 188 million messages, you are charged USD 0.4 per million messages.

  • Device connection duration fee

    Device connection duration: 60 × 8 × 30 × 10,000 = 144,000,000 minutes

    Device connection duration fee: 144 × 0.3 = USD 43.2. Note: You are charged USD 0.3 per million minutes.

  • Total monthly fee: 125.2 + 43.2 = USD 168.4

Example 3

10,000 devices go online twice a day. The devices remain online for 2 hours at the first time and 6 hours at the second time. The devices are online for a total of 8 hours a day. During the online period, each device sends a message of 0.6 KB per minute. Each device receives a message of 0.4 KB per minute. The current month has 30 days.

The fees for the current month are calculated based on the following billable items:

  • Messaging fee

    Number of messages sent in the current month: 60 × 8 × 30 × 10,000 × 2 = 288,000,000

    Note Each message that is sent has a size of 0.6 KB, which is greater than 512 bytes. Therefore, IoT Platform calculates each message as two messages. For more information about how IoT Platform calculates messages, see Billing methods.

    Number of messages received in the current month: 60 × 8 × 30 × 10,000 = 144,000,000

    Total number of messages: 288,000,000 + 144,000,000 = 432,000,000

    Messaging fee: 100 × 0.5 + 332 × 0.4 = USD 182.8. Note: For the first 100 million messages, you are charged USD 0.5 per million messages. For the excess 332 million messages, you are charged USD 0.4 per million messages.

  • Device connection duration fee

    Device connection duration: 60 × 8 × 30 × 10,000 = 144,000,000 minutes

    Device connection duration fee: 144 × 0.3 = USD 43.2. Note: You are charged USD 0.3 per million minutes.

  • Total monthly fee: 182.3 + 43.2 = USD 226
