Insert SIM card fault

Troubleshooting flow

The hardware of the SIM interface from UEMCLite (D2200) 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”.
