Hi,

the latest FW version is 0.18. I checked this command with the latest FW and it worked fine.  
Please see the log below.

// check FW version  
AT+CGMR  
SIERRA HL6N,000.18  
OK

// check SIM status  
AT+CPIN?  
+CPIN: READY  
OK

// use the +CRSM command  
AT+CRSM=176,12258,0,0,10  
+CRSM: 144,0,“9868001F912198087939”  
OK

Please use the latest FW version and share the AT logs if problem still persists.

Thanks
