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 MC55 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)
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>
