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: 
AT^SCKS=1
Activates the presentation of unsolicited result codes
OK
^SCKS: 1
Tray connected
^SCKS: 0
No SIM card found
