AC75 AT Command Set

14.5 AT^SCKS

s

<SimStatus>(num)(&V)

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".

If the Remote SIM Access feature is activated (refer to AT^SRSA) and a SIM card error occurs while accessing the remote SIM, the AC75 switches to its local SIM, if any. If the SIM card error occurs while local SIM access, use of the remote SIM is still possible.

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.

If Remote SIM Access switches back from remote to local SIM, SCKS indicates the status 1 regardless of the real SIM status. If no SIM is inserted this is followed by a second SCKS URC indicating 0.

Example

AT^SCKS=1

Now, after inserting an empty card tray the following URCs appear:

^SCKS:
