Ah ok, I think it's just that the SIM is responding with a blank name:

[src/mm-port-serial-at.c:459] debug_log(): (ttyMux1): --> 
'AT+CRSM=176,28486,0,0,17<CR>'
[src/mm-port-serial-at.c:459] debug_log(): (ttyMux1): <-- '<CR><LF>+CRSM: 
144,0,"FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF"<CR><LF>'
[src/mm-port-serial-at.c:459] debug_log(): (ttyMux1): <-- '<CR><LF>OK<CR><LF>'

So simply hasn't been set by the operator/supplier I guess
