The write command enables or disables the presentation of URCs to report whether or not the SIM card is con-
nected.
If the ME is powered down or reset (
AT+CFUN or AT^SMSO) the current presentation mode setting <mode> will
not be retained. Therefore the setting
<mode>=1 needs to be restored after power on the MC35i or may be saved
in the user profile (
AT&W).
Parameter Description
0
(&F)
Suppress unsolicited result codes
1 Output unsolicited result codes
0 Card holder tray removed or SIM connection error
1 SIM inserted(refer to note)
2 The SIM interface HW has been deactivated to prevent possible damage (e.g.
if a SIM with invalid or unsupported electrical specifications has been
detected).
The SIM interface can be reactivated only with a restart of the module, e.g. with
"
AT+CFUN= n,1".
Note
• <SimStatus> reflects the status of the SIM and the card holder tray. Therefore if an empty SIM card tray is
inserted, two URCs will be presented, indicating the status 1 followed by 0, i.e. a SIM is inserted into the card
holder tray but no SIM connection could be established.
Example
Now, after inserting an empty card tray the following URCs appear:
<mode>
(num)(&W)(&V)
<SimStatus>
(num)(&V)
