Message expiration
Ensure your account has enough messages for your products and devices before they expire. Expired messages can disrupt device communication.
What is a message validity period?
IoT Platform uses messages to communicate between the cloud and devices. Each message package has a validity period. After this period ends, the messages in the package expire and can no longer be used for device reporting.
When you first purchase a device activation code, the included messages are valid for three years.
Additional message packages purchased for active devices are valid for one year.
Effects of message expiration
After messages expire, devices can no longer report messages. This prevents device status synchronization.
This can pose a threat to your device automation. To avoid disrupting your business, purchase an additional message package before your current messages expire. For more information, see Message billing.
