SIM5350 AT Command Set
This command refers to Advice of Charge supplementary service that enables subscriber to get
information about the cost of calls. With <mode>=0, the execute command returns the current call
meter value from the ME.
This command also includes the possibility to enable an unsolicited event reporting of the CCM
information. The unsolicited result code +CCCM: <ccm> is sent when the CCM value changes, but
not more that every 10 seconds. Deactivation of the unsolicited event reporting is made with the
same command.
