Emport provides the ability to set a data usage threshold so that when the usage in the current billing period exceeds it, a data cap is requested. This facility is commonly used by the customer to request a cap when the SIMs's usage has exceeded its allowance.
When the SIM reaches the cap threshold an email is sent to the customer stating that the SIM has reached its data cap threshold and no further data sessions will be allowed.
The data cap threshold, and the list of email addresses to which the notification is sent, are configured in the SIM Details screen.
In addition, for operators that support it, the customer can request that the data session is terminated when the data cap threshold is exceeded. This is configurable in the SIM Details screen. See SIM Capabilities for the list of operators that support these "hard caps".
Important note: For SIMs where the operator doesn't support hard caps, if the SIM is in an existing data session and exceeds its data cap threshold, data usage will continue until the current session comes to an end.
