Description

Set command sets the Advice of Charge related accumulated call meter maximum value in SIM card or in the active application in the UICC (GSM or USIM) file EF_ACMmax. ACMmax contains the maximum number of home units allowed to be consumed by the subscriber. When ACM (refer +CACM) reaches ACMmax calls are prohibited (see also 3GPP TS 22.024 [26]). SIM PIN2 is usually required to set the value. If setting fails in an MT error, +CME ERROR: <err> is returned. Refer clause 9.2 for possible <err> values.

Read command returns the current value of ACMmax.

Defined values

<acmmax>: string type; accumulated call meter maximum value similarly coded as <ccm> under +CAOC; value zero disables ACMmax feature

<passwd>: string type; SIM PIN2

Implementation

Optional.
