nRF9151 DK UICC failure / no SIM VCC after previous SoftSIM usage

Question

I’m facing a UICC failure issue on multiple nRF9151 DKs. 
 Symptoms: 
 
 AT+CPIN? returns ERROR 
 %XSIM: 0,9 
 SIM VCC is not present (no 1.8 V observed) 
 Nordic stock examples that previously worked now also fail 
 Same physical SIM works correctly on a custom nRF9151 board that has never used SoftSIM 
 
 Commands/results: 
 AT%XVBAT
%XVBAT: 5035
OK

AT+CPIN?
ERROR

AT%XSIM?
%XSIM: 0,9
OK

AT+CFUN?
+CFUN: 1
OK 
 What I already tried: 
 
 Full chip erase/recover 
 Reflashed modem firmware 
 Tested with Nordic sample applications 
 Power cycle/reset 
 Different SIM cards 
 Verified SIM works on another board 
 
 Important detail: All affected DKs had previously been used for SoftSIM/eSIM experiments. 
 At this point I’m trying to determine: 
 
 Whether %XSIM: 0,9 specifically indicates a hardware-level UICC failure 
 Whether the modem suppresses SIM VCC if it detects an electrical fault on SIMIO/CLK/RST 
 Whether anyone has seen permanent UICC damage after SoftSIM experiments or SIM line contention 
 Whether there are additional modem/UICC recovery procedures beyond full erase + modem FW reflash 
 
 Would appreciate any guidance on: 
 
 interpreting %XSIM: 0,9 
 checking the SIM power path 
 confirming whether this is likely permanent hardware damage 
 
 Thanks,
