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 c ard

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)
