Ok, so after some more experiments:

ofonod[3057]: drivers/atmodem/sms.c:construct_ack_pdu()
> AT+CNMI=1,2,2,1,0
< OK
ofonod[3057]: src/network.c:__ofono_netreg_add_status_watch() 0x538bf0

Modem does not like our CNMA acknowledgement. AFAICT, we are sending

AT+CNMA=1,2
0000^Z

If I attempt to do AT+CNMA=1, AT+CNMA=0 or just plain At=CNMA, it does
not like that, either, but with +CMS ERROR: 500.

Is "0000" correct thing to send for message acknowledge?

Best regards,
