MKR NB 1500 SIM Card Issue

I am trying to get a MKR NB 1500 work with a LTE-M SIM card, but SARA module is having issue interfacing with SIM card. The SIM does not have PIN.

Looks like the SARA module is working. With SerialSARAPassthrough sketch loaded, I get replies to AT command specific to radio modem:

AT+GMM 
SARA-R410M-02B
 
AT+CGSN
352xxxxxxxxxxxx

(intentionally masked)

AT+GSN
352xxxxxxxxxxxx

(intentionally masked)

AT+CPAS
+CPAS: 0
 
AT+CFUN?
+CFUN: 1
 
AT+CIND?
+CIND: 5,0,0,0,0,0,0,0,0,0,0,2
 
OK
AT+URAT?
+URAT: 7

However when issuing SIM related AT commands they give “SIM failure/SIM not inserted/SIM PIN required” errors, like so

AT+CIMI
+CME ERROR: SIM failure
 
AT+CCID
+CME ERROR: SIM failure
 
AT+COPS?
+CME ERROR: SIM failure
 
AT+CREG?
+CME ERROR: SIM failure
 
AT+CNUM
+CME ERROR: SIM PIN required
 
AT+CPIN?
+CME ERROR: SIM not inserted

I traced the pins on the SIM card holder and I find something funny - I am getting 0V on SIM VCC.

Anybody experience similar issue?
