number of home units for both the current and preceding calls.
Read command reports the current value of the SIM ACM in the format:
+CACM: <acm>
where:
<acm> ‐ accumulated call meter in home units, string type: three bytes of the ACM value in hexadecimal format
(for example “00001E” indicates decimal value 30)
Note: The value <acm> is in home units; price per unit and currency are defined with command +CPUC

Accumulated Call Meter Maximum +CAMM
Set command sets the Advice of Charge related Accumulated Call Meter Maximum Value stored in SIM (ACMmax).
This value represents the maximum number of home units allowed to be consumed by the subscriber. When ACM
reaches <acmmax> value further calls are prohibited.
Read command reports the ACMmax value stored in SIM in the format:
+CAMM : <acmm>
where:
<acmm> ‐ ACMmax value in home units, string type: three bytes of the ACMmax value in hexadecimal format (for
example “00001E” indicates decimal value 30)
Test command returns the OK result code.
