Ah. Four zeros somehow looked too simple to me.

Heh :-). Well, there are two phones with reasonable Linux support:
N900 and Droid 4. N900 can't do voice calls of reasonable
quality. That leaves Droid 4... so I'd really like it to work.

Afaict.. In PDU mode we need either +CNMA, which is broken, or CMTI,
which reports '+CMTI: "ME",-1' which I assume is broken, too.

Is there chance that '+CMTI: "ME",-1' can be understood as '+CMTI:
"ME",1' ?

Best regards,
