CME ERROR 50 when entering PIN during setting up new modem | Telit Cinterion IoT Developer Community

I’m setting up a brand new modem for SMS texting. But when entering the PIN I’m receiving CME ERROR 50.

Can you explain the reason for this error?


The SIM card works fine in a normal phone.


Setup is done using these commands:

AT&F<13> (Set to factory default)

ATE0<13> (Disable Echo)

ATQ0<13> (DCE Transmit result code)

ATV0<13> (Short Result Code Format)

AT+CMEE=1<13> (Enable error result code with numeric values)

AT+CMGF=0<13> (SMS PDU Mode)

AT+CPIN?<13> (Check PIN) => +CPIN: SIM PIN<13><10>0<13>

AT+CPIN=1642<13> (Enter PIN) => +CME ERROR: 50<13>


Trying to use AT+CNMI=2,0,0,0,1 produces the same error.


Result of ATI1:

Cinterion, EHS6, REVISION 03.001, A-REVISION 00.000.42
