AT Commands Reference
4.3.4.3 +CAOC, Advice of Charge
This command enables the subscriber to get information about the cost of calls. If supported, this command also
activates/deactivates unsolicited event reporting of the CCM (Current Call Meter) information.
The unsolicited report +CCCM:<ccm> is sent when the CCM value changes, but not more than once every 10 seconds.
Set Command
The Set command returns the CCM value from the g20, or activates/deactivates unsolicited reports.
Read Command
The Read command returns the current CAOC mode.
Test Command
The Test command returns the supported mode values.
Note
The CCM value depends on the network properties (charge for MO or/and MT calls). There are no +CCCM
unsolicited reports after power-cycle automatically, it should be activated.
There are two states in which the command can be activated:
• In IDLE state - returns the last call cost.
• In a voice/data state - returns the accumulated cost, including the current call.
