consume. When ACM (see +CACM) reaches ACMmax, calls are prohibited. SIM PIN2 is required to set
the value. If setting fails in an ME error, +CME ERROR: <err> is returned.
The Read command returns the current value of ACMmax.
The ACMmax value (entered or displayed) is in hexadecimal format with 6 digits.
