Insert SIM card fault

Troubleshooting flow
The hardware of the SIM interface from UEMC/Litti (D2901) to the SIM connector (X2700) can be tested without
a SIM card. When the power is switched on the phone first check for a 1.8V SIM card and then a 3V SIM card.
The phone will try this four times, where after it will display "Insert SIM card".
