I'm saying this modem is broken in more than one way, yes. I tried
CNMI=3D1,1, but that did not work too well:

ofonod[2935]: drivers/atmodem/sim.c:at_crsm_read_cb() crsm_read_cb:
90, 00, 30
> AT+CNMI=3D1,1
< OK
ofonod[2935]: src/network.c:__ofono_netreg_add_status_watch() 0x53bbf0
...
ofonod[2935]: src/modem.c:get_modem_property() modem 0x53b000 property
SystemPath
ofonod[2935]: plugins/upower.c:battery_props_changed()
< +CMTI: "ME",-1
ofonod[2935]: Unable to parse CMTI notification
< +CIEV: 7,1

I'm getting the +CMTI: "ME",-1 indication in other cases, too :-(.

Invalid SMTI indication, AFAICT :-(. Let me play some more...

Thanks for the pointer.
